Formerly + the lines were stacked on top of each other. Normally this wasn't too much of an issue + unless you wanted semi-transparent colours. Because the lines were stacked on top of + each other the colors wouldn't be exactly right. This has now changed so you CAN now use + semi-transparent colors. + + As a result the order in which the lines are drawn has been changed, so whilst the data + will remain the same, the "stacking" order if the datasets may change. Also, if you use + an array of shadow colors, they may need reversing. + o [MISC] The download archive now works "out-of-the-box" with IE9. Formerly the DOCTYPE wasn't the first line + in the files so it choked.

This is the index + in the individual array for a particular line. If you're not using multiple lines in your chart, this won't affect + you. + + 17th July 2011 + ============== + o [BAR] Added chart.colors.reverse for reversing the order in which colors are used (stacked bar charts only) + o [FUNNEL] Added a .getSegment(e) method - which greatly simplifies retrieving the segment that has + been clicked on (or the mouse is over etc). + o [LINE] Added chart.key.interactive - this allows you click on a key item and it will be highlighted on the chart + o [TOOLTIPS] Small fix to snap effect when you have multiple charts one one page, both with tooltips + o [TOOLTIPS] The default CSS has been altered for tooltips. This affects all chart types.

Instead of just one radius value, there are now two + radius values - the start and end values. This change was necessary to facilitate stacked Rose charts. + Subsequent values have "moved up one" in the array (ie what was index 3 is now 4, what was 4 is now 5 + and what was 5 is now 6) + o [SCATTER] The chart.tooltips.coords.adjust property has been removed + + 21st June 2011 + ============== + o [DONUT] Added chart.variant.donut.color for the center hole + o [HBAR] The default colors have changed + o [HBAR] Added sequential color support to grouped and stacked HBars + + 18th June 2011 + ============== + o [HBAR] Added chart.colors.sequential for regular hbars (not stacked or grouped) + o [HBAR] Converted to .getBar(e) method for tooltips + o [LINE] Added triangle and filledtriangle tickmark types + o [ODO] Added chart.green.solid and documented + o [ODO] Added chart.yellow.solid and documented + o [ODO] Added chart.red.solid and documented + o [ODO] Documented chart.green.color + o [ODO] Documented chart.yellow.color + o [ODO] Documented chart.red.color + o [PIE] Added chart.variant.donut.color - this controls the color of the hole + o [ROSE] Implemented stacked Rose chart (see below) + o [ROSE] Added chart.colors.sequential (which, if you upgrade, you need to set to true to maintain BC) + o [ROSE] When using tooltips, the highlight will now appear "over" the axis labels. This makes the + highlighted segment more identifiable. + o [ROSE] Tooltips can now be a single function, or an array of functions as well as an array of strings + o [ROSE] Added chart.variant - the value can be either null (for a normal or stacked Rose chart) or "non-equi-angular" for a + Rose chart that has unequal segment sizes. See an example here: + + http://dev.rgraph.net/tests/2011-07-30/non-equi-angular_rose.html + + o [ROSE] Added chart.labels.offset + o [ROSE] Added chart.tooltips.event + o [SCATTER] Added in-graph labels to Scatter chart + + The Rose chart has undergone significant changes in order to facilitate stacked and non-equi-angular charts. + In particular, the color handling has changed, and as such you may need to specify chart.colors.sequential in + your chart configurtion to get the colors to behave as they used to. Changing the way colors behave brings the Rose chart + into line with other chart types. Also, the Rose chart .getSegment() return value has changed - now instead of just one radius + value, you get a start radius and end radius value. + + 7th June 1011 + ============= + o [LINE] Documented chart.filled.accumulative + o [WEBSITE] Removed redundant checks from graph libraries + + 4th June 2011 (STABLE) + ============= + o [MISC] Stable release - see .BC.txt, and look through this files entries since the last stable release (25-03-2011) + + 28th May 2011 + ============= + o [LINE] You may need to adjust your titles vertical positioning using chart.title.vpos + o [MISC] Added example of adding a subtitle to your graph + + 21st May 2011 + ============= + o [BIPOLAR] Tooltip handling has changed. If none is set for a particular bar, none will now be shown + o [COMMON] Check your graph titles - the vertical positioning has changed. To reposition you can + use chart.title.vpos + o [HBAR]The X axis title positioning may have changed slightly - if you use it you should check your title is as you expect + o [HBAR] chart.labels.above has been fixed in respect of drawing text in a stacked HBar for sections that it shouldn't do + o [HBAR] Fixed a very minor bug when the chart is redrawn (after being drawn once) and the scale wasn't correctly reset + o [LINE] This chart type may be particularly buggy because of the gutter changes + o [MISC] Individual gutters are now settable with all graph types + o [MISC] The settings chart.width and chart.height are now deprecated in favour of the new individual gutter settings + o [ODO] Added key - helpful for multiple pointers + o [RESIZE] Repositioning the resize handle is no longer necessary with the introduction of independent gutter settings. + Starting with the May release this setting should no longer be used. + o [SCATTER] Added an obj.getPoint(e) method which eases getting the point (if any) that is currently being hovered over + o [WATERFALL] Documented chart.scale.formatter + + Keep in mind that individual gutter settings and using chart.width/chart.height are not meant + to be used together - chart.width/chart.height will cease to be user facing properties and will + (starting this release) stop functioning and be removed completely. The addition of individual + gutter settings is a fundamental change so testing of your graphs is imperative.

RGraph: HTML5 Javascript charts library - Adjusting your charts interactively

+ + + +
+

+ Since 24th May 2010 you have had the ability to adjust your so if you want to see the charts interactively. Currently the Bar chart, Line chart, + Progress Bar, Rose chart and the Radar have this facility. Some chart types use multiple event handlers and as such + are unlikely to work well with other dynamic features. The Line chart is an example of this, and whilst it does work + with the context menu (and so the full canvas zoom), it is unlikely to work with other dynamic features. +

+ + +

+ At the current time this feature on the Bar and Line charts doesn't work with X axis in the center. +

+ + +

+ If your intention is to make some sort of interactive console, new HTML5 input types may also be of interest (for example the new range input type + which gives you a "slider bar"). Eg (Chrome/Safari/Opera): +

+ +

+ + +

+ +

Note

+ +

+ Since interactivly adjusting a chart involves completely redrawing it, having a lot of them on one page can cause + slower updates. For this reason each example chart is on its own page: +

+ + + +

DOM2 event handlers

+ +

+ In January 2011 all adjusting was converted to DOM2 event handling. This makes adjusting work much better with other + dynamic features. +

RGraph: HTML5 Javascript charts library - Adjusting your charts interactively - Gantt chart

+ + + +

+ The Gantt chart can be adjusted by dragging the bars left or right, or the events can be resized if you place the cursor at the + right edge of the event. To get the details of the bar being dragged you can use the + onadjustend event, and in that you can look at the RGraph registry - RGraph.Registry.Get('chart.adjusting.gantt') The + returned array consists of: + +

    +
  • The numerical index of the event being adjusted (corresponding to the chart.events array that you set).
    • +
  • The chart object
    • +
  • The starting X position of the bar (before the chart was adjusted)
    • +
  • The starting Y position of the bar (before the chart was adjusted)
    • +
  • The original numerical value (in relation to your chart.xmax) that the bar started at
    • +
+

+ +

+ When adjusting is complete the chart.events array is updated. So you can use the numerical index that you find in + the registry (as above) with the chart.events array to get up-to-date event information. +

+ +

+ Note: + The Gantt chart uses console.log() to send notifications. Press CTRL+SHIFT+J in Chrome to see the console, or use Firebug in + Firefox. Other browsers will vary. +

RGraph: HTML5 Javascript charts library - Making annotations shareable cross browser

+ +
+
+ This example does not work offline - you must use a website. Annotations are removed every five minutes. +
+
+ + + + [No canvas support] + +

+ Combining a little AJAX and some very simple server side scripting, you can easily make an annotation system that can persist + across different browsers and computers. You an either use Load/Save buttons to trigger the loading and saving, or like the + example to the right you can make use of the custom RGraph onannotateend event to make it happen automatically. +

+ +

+ This simple example uses a small PHP server side script that loads and saves the annotation data to a file on the server, + and that looks like this: +

+ +
+ + 
+<?php
+    $file = '/tmp/annotation_data';
+
+    /**
+    * Save the annotations to a tmp file
+    */
+    if (isset($_POST) && isset($_POST['data'])) {
+        file_put_contents($file, $_POST['data']);
+        exit;
+    }
+
+
+    /**
+    * Load the annotations
+    */
+    if (!empty($_GET['getannotations']) && $_GET['getannotations'] == 1) {
+        $contents = file_get_contents($file);
+        print($contents);
+        exit;
+    }
+?>
+
+ +

+ By making the Javascript Save/Load functions repeat themselves every few seconds, you could easily make a presentation/demo system + that can be used when paticipants are in differing locations - in a similar fashion to Google Docs - or when you want one persons + annotations to be viewable by multiple PCs. On this page though, the Save function is triggered by the custom RGraph event + onannotateend. +

RGraph: HTML5 Javascript charts library - Annotating your charts

+ + + +
+ [No canvas support]
+
+ +

+ The annotations feature brings presentation style functionality to RGraph charts. You can use this feature + for highlighting your charts if you need to. +

+ + + + +

How do annotations work?

+ +

+ Enabling annotations is a very simple affair, and consists of doing the following: +

+ + 
myGraph.Set('chart.annotatable', true);
+ + +

Browser support

+ +

+ Annotations are supported in all browsers that RGraph works with - Firefox 3.5+, Chrome 2+, Safari 4+, Opera 10.5+ and + MSIE/Google Chrome Frame. They DO NOT however work with MSIE 8/ExCanvas. +

+ + +

What can I use annotations for?

+ +

+ As mentioned you can use it for presentations, highlighting things to yourself or others or just to have fun drawing (!). +

+ + +

Are annotations persistent?

+ +

+ That depends on which browser you're using. The annotation data is stored in the users web browser (not on the web server), + meaning currently (21st March 2010) browser support is limited to Firefox 3.5+, Safari 4+, + Chrome 4+ and Opera 10.5+. MSIE 8 also has the required storage capabilities, but since it doesn't yet support canvas, the point is moot. + The user does not have to + confirm anything for storage to be allowed - try it out on this page by drawing on the chart and then refreshing the page. +

+ + +

How do I show the mini-palette?

+ + +

+ You can show the palette by using the RGraph.Showpalette function shown below as a context menu item: +

+ + 
+myObj.Set('chart.contextmenu', [
+                                ['Show palette', RGraph.Showpalette],
+                                ['Clear', function () {RGraph.Clear(myObj.canvas); myObj.Draw();}]
+                               ]);
+
+ +

+ This code will result in the same context menu as the chart above. +

+ + +

How can I clear the annotations?

+ + You can simply clear the chart and redraw it: + + 
RGraph.Clear(myGraph.canvas); // Clear the chart
+myGraph.Draw();               // Redraw it
+ +

+ In the chart above, there is a context menu that allows you to both clear the chart and also demonstrates the mini-palette + feature available to you. +

+ + +

Replaying annotations when they're off

+

+ When annotations are not enabled, any prior annotations that may have been made are not displayed. To show them you need + to use the API function RGraph.ReplayAnnotations(object) after the call to .Draw(). +

+ + +

Making your annotations persist across browsers/computers

+

+ With a little bit of custom Javascript and some server side scripting you can make your annotations persist across + different browsers/computers. You can find an example of this here. +

RGraph: HTML5 Javascript charts library - API documentation

+ + + +
+ + + + +

Overview

+ +

+ Working with RGraph objects is purposefully easy, to make them straight forward to integrate into your own scripts if you want to. For any + particular chart type there are a few files required - the common libraries and the chart specific library. Eg: +

+ + 
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.bar.js"></script>
+
+ +

+ RGraph.common.core.js is a function library that contains a large set of functions that support the chart classes. + Some functions, and sets of functions, have their own files. For example, the zoom functions reside in RGraph.common.zoom.js, + so if you don't need zoom, you don't need this file. + Each of the chart libraries (RGraph.*.js) contains that particular charts class. If you'd like to see a "bare bones" + implementation, you can look at the basic example. There's also a + skeleton example to make it easier to create new chart types. +

+ + +

Canvas and context references

+ +

+ Each chart object maintains references to the context and canvas as properties. So to get hold of them all you + need to do is this: +

+ + 
+<script>
+    window.onload = function ()
+    {
+        // 1/2 First draw the chart
+        var myBar = new RGraph.Bar('myCanvas', [1,5,8,4,6,3,1,5,7,8,4,6]);
+        myBar.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+        myBar.Draw();
+    
+        // 2/2 Now get hold of the references
+        var context = myBar.context; // Get hold of a reference to the context
+        var canvas  = myBar.canvas;  // Get hold of a reference to the canvas
+    }
+</script>
+
+ + +

Working with events

+ +

+ When working with events, you may come across the situation where you have a reference to the canvas, but + also need to access the chart object. For this reason the constructor of each object adds a reference to the object to the + canvas and you can access it like this: +

+ + 
+<script>
+    document.getElementById("myCanvas").onclick = function (e)
+    {
+        var src = (RGraph.isIE8() ? event.srcElement) : e.target;
+    
+        // The RGraph object constructors add __object__ to the canvas.
+        var myBar = src.__object__;
+    }
+</script>
+
+ + +

Working with chart coordinates

+ +

+ For most chart types, the coordinates of elements (eg bars, lines etc) are to be found in the class variable obj.coords. + This is usually a multi-dimensional array consisting of the coordinates of those shapes, or of points. As an example the bar + chart maintains the X, Y, width and height of each bar (or sections of bars in a stacked bar chart). The coords array is + usually a flat array, even when you have multiple sets of data. +

+ +

+ By using the RGraph.getMouseXY() function and this array you can determine if a bar was clicked on, or if the mouse is near a + line point etc. +

+ + 
+var myCoords = myBar.coords;
+
+ +

+ Note: Previously the coords array values sometimes included the margin values, and sometimes didn't. As of 17th + April 2010 the values have all been unified to not include the margin values, so the values are as reported. +

+ +

+ Note: + The Line chart also has an object variable myObj.coords2, where the coordinates are indexed differently - + by line index. +

+ + +

Working with chart data

+ +

+ Another variable you may need is the data variable. For most chart types, this is where the data is stored. It is usually + untouched, so it is as you supplied to the chart objects constructor. A notable exception to this is filled line charts. + Here the original data is stored in the class variable original_data. The data supplied is modified to produce the stacking + effect. If you need to modify a filled line charts data you will need to change this variable instead. +

+ +

+ Not all chart types use the data variable. For some the name is different so that it makes a little more sense. The + chart types and their associate data variables are listed below1. +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

  1. In the table, obj refers to your chart object.
    2. +
  2. For the Scatter chart, each data point is an array of X/Y coordinates, the color and the tooltip for that point.
    3. +
  3. + The Line chart obj.original_data is an aggregation of all the datasets given to the Line chart, so the first + dataset is held in obj.original_data[0], the second in obj.original_data[1] etc. +
    4. +
+ + +

Updating your charts dynamically

+ +

+ Note: + It is important that you're careful with types when making AJAX requests. Since the response is initially a string, + and your AJAX function/library may not do conversions for you, you may need to convert these strings to numbers. To + do this you can use the Number() or parseInt() functions. For example: +

+ + 
+<script>
+    num = Number('23');
+    num = parseInt('43');
+</script>
+
+ +

+ A common request is to be able to update charts dynamically. This is quite simple and consists of three steps: +

+ +
    +
  1. Get the new data from the server (with an AJAX request for example).
    2. +
  2. Set the data in your chart object. See the above table for the appropriate property to use.
    3. +
  3. Call the .Draw() method again.
    4. +
+ +

+ If you don't need to get data from your server (ie it's all client-side) then you can omit the first step. Also, it may be + sufficient to simply recreate the entire object from scratch. This means that you won't have to alter and + RGraph internal properties - just recreate the chart object and configuration. There's a simple function + you can use for AJAX purposes here. +

+ + + +

Setting properties

+ +

+ To set RGraph properties, ideally you should use each objects setter (there's also a corresponding getter). These functions + accomodate some backwards compatibility changes, so by not using them you run the risk of your charts not working entirely as + expected. +

+ + 
+myObj.Set('chart.gutter.left', 25);
+myObj.Get('chart.gutter.left');
+
+ + +

 

+

References available on RGraph objects

+

+ RGraph stores various references to objects on the canvas (typically) to make getting hold of them easier. There's also a + Registry object in + which references are stored. Typically the objects are named with the format __xxx__, and you can inspect the + objects by using a console(eg the inspector that's part of Google Chrome - CTRL+SHIFT+J). Some examples are: +

+ +
    +
  • __object__ on the canvas - a reference to the chart object
    • +
  • + RGraph.Registry.Get('chart.tooltip') - a reference to the currently visible tooltip. This in turn has the following + available: +
      +
    • __text__ - Since setting .innerHTML can cause changes in HTML, this is the original tooltip text.
      • +
    • __index__ - This is the numerical index corresponding to the tooltips array that you set.
      • +
    • __dataset__ - Used in the Scatter chart and corresponding to the dataset.
      • +
    • __canvas__ - A reference to the original canvas that triggered the tooltip.
      • +
    +
    • +
  • + RGraph.Registry.Get('chart.mousedown') - Used in annotating, and stipulates whether the mouse button is currently + pressed. +
    • +
  • + RGraph.Registry.Get('chart.contextmenu') - The currently shown context menu, if any. This in turn has the following + properties: +
      +
    • __canvas__ - The original canvas object.
      • +
    +
    • +
+ + These are just a sample of what's available, to find more you should use an introspection tool or look at the source. + + + + +

Scale information

+

+ For the Bar, Bipolar, HBar, Line and Scatter charts the scale that is used is stored in the scale class variable. Eg: +

+ + 
+<script>
+    var myBar = new RGraph.Bar('cvs', [56,43,52,54,51,38,46,42,52]);
+    myBar.Draw();
+    
+    var myScale = myBar.scale
+</script>
+
+ + +

Adding text to your charts

+

+ If you want to add arbitrary text to your chart(s) you can use the API function RGraph.Text(). +

+ + 
+<script>
+    // Draw a basic chart
+    var myObj = new RGraph.Bar('myCanvas', [4,5,5,8,7,6,4,8,5,9]);
+    myObj.Draw();
+    
+    // Draw some text
+    myObj.context.beginPath();
+        size = 12;
+        font = 'Verdana';
+        text = 'Some text!;
+        x    = 10;
+        y    = 10;
+
+        RGraph.Text(myObj.context, font, size, x, y, text);
+    myObj.context.fill();
+</script>
+
+ + +

    File: RGraph.common.core.js

    • +
  • + (null) RGraph.ClearAnnotations(id)
    This function clears the annotation data associated with the given canvas ID (but DOES NOT redraw the chart). If you want to clear the visible annotations too, you will need to redraw the canvas. You could do this using the following code: +
    + 
    +function ClearAndRedraw (obj)
+{
+    RGraph.Clear(obj.canvas); // This function also calls the RGraph.ClearAnnotations() function
+    obj.Draw();

    File: RGraph.common.annotatate.js

    +

    • +
  • (null) RGraph.ReplayAnnotations(object)

    In conjunction with the previous function, this is an implementation of the Registry pattern which can be used for storing settings.
    File: RGraph.common.core.js

    • +
  • (null) RGraph.Register(object)
    This function is used in conjunction with the next to register a canvas for redrawing. Canvases are redrawn (for example) when tooltips or crosshairs are being used.
    File: RGraph.common.core.js

    • + +
  • + (null) RGraph.Redraw([id, [color]])
    This function is used in conjunction with the previous to redraw a canvas. Canvases are redrawn (for example) when tooltips or crosshairs are being used.

    Note: All canvases that are registered are redrawn. However the optional first argument can be an ID (a string) of the canvas that is NOT to be redrawn. The optional second argument is the color to use when clearing canvases.

    +
    • + +
  • (null) RGraph.SetShadow(object, color, offetX, offsetY, blur)

    File: RGraph.common.core.js

    • +
  • (null) RGraph.NoShadow(object)

    File: RGraph.common.core.js

    • +
  • + (number) RGraph.Async(mixed[, delay])
    This is a simple function but has significant implications on your pages performance. You + can pass this either a function pointer, or a string containing the code to run and it will run the code asynchronously (ie in + parallel to the page loading). In doing so it can mean that your page is displayed faster, as the chart is created + seperate to the page loading. As such, the placement of your canvas tag becomes more important. What you can do is + define the canvas tag and then the code to produce the chart immediately after it. This is how the front page is coded, + (but not using the RGraph.Async() function). + There's an example of it here. The optional delay argument is measured in milliseconds + (1 second = 1000 milliseconds) and defaults to 1. What you can do is specify something like 1000 to make the effect + more pronounced to ensure it's working as expected. + +

    + Note: Since a dev release of version 4, Google Chrome versions 4 and 5 have an issue with rendering text when using + the RGraph.Async() function. The solution here is to simply not use the RGraph.Async() function. +

    + File: RGraph.common.core.js

    +
    • + +
  • + (null) RGraph.Reset(canvas)
    + This function resets the canvas. At first this function may appear similar to the RGraph.Clear() function, however this + function will reset any translate() that has been performed, and so can stop them accumulating. +

The skeleton file

+

+ The skeleton object + (RGraph.skeleton.js) gives you a base for creating new chart types that + match the RGraph object system (eg getters, setters, RGraph names etc). Example usage of the skeleton object would be: +

+ + 
+<script>
+    var myObj = new RGraph.Skeleton('cvs', [3,3,4,5,3,8,3,2,1,9]);
+    myObj.Set('chart.colors', ['red']);
+    myObj.Draw();
+
+    var colors = myObj.Get('chart.colors');

RGraph: HTML5 Javascript charts library - Asynchronous processing

+ + + +

Waiting for onload event...

+ +

+ + + + + These images are here to pad the page and slow down loading so that the window.onload event is slowed. This makes the + difference far more visible. +

+ + [No canvas support] + + + +

+ Asynchronous processing can speed up the display of your charts, because the browser gets to your code, sets it + going and then continues on rendering the page. Particularly if you have a weighty page, + it can make quite a difference. The RGraph.Async() function itself is very simple, but because it can make + a significant difference to the speed of your page, it is documented here. There's an example of it to the right. + One thing to remember is to ensure your canvas tag is defined first before you set the function that creates + the chart going. +

+ +

+ Although asynchronous processing can speed up your pages, it can also give the appearance of slower pages due to partial + rendering, (ie your pages render a bit at a time). You therefore will need to experiment to get the best result for you. +

+ +
+ + 
+<script src="RGraph.common.js"></script>
+<script src="RGraph.line.js"></script>
+
+<canvas id="myCanvas" width="300" height="100">[No canvas support]</canvas>
+
+<script>
+    /**
+    * Create the line chart
+    */
+    function CreateLineGraph ()
+    {
+        var line = new RGraph.Line('myCanvas', [1,2,4,2,1,3,5,6,6,5,3,5]);
+        line.Set('chart.title', 'Sales for Acme Inc.');
+        line.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+        line.Set('chart.hmargin', 10);
+        line.Set('chart.linewidth', 5);
+        line.Set('chart.shadow', true);
+        line.Set('chart.shadow.offsetx', 0);
+        line.Set('chart.shadow.offsety', 0);
+        line.Set('chart.shadow.blur', 15);
+        line.Draw();
+    }
+
+    RGraph.Async(CreateLineGraph);
+</script>
+
+ +

Things to remember

+ +
    +
  • All your libraries must be loaded first. In the pages <head> for example. If not, you won't be able to create your charts.
    • +
  • Your <canvas> tag must be defined before setting the asynchronous code going. If not, then the canvas may be referenced before it exists, and thus your charts will not be created.
    • +
  • + The users connection speed may be a factor. Slower connections may mean, for example, that the onload event doesn't fire very + quickly. If you're using the onload event to create your charts then asynchronous creation instead may give you more + apparent speed ups. Alternatively, careful placement of the <canvas> tag and the code that creates the chart may suffice + instead. +
    • +
  • Since the MSIE/ExCanvas combo requires you to use the window.onload event, asynchronous chart creation in this case will probably not be any help.
    • +
  • + Since a dev release of version 4, Google Chrome has had an issue when asynchronous processing is used, meaning that + text isn't always displayed. The solution here is simply to not use asynchronous processing. As of 27th March 2010, + Chrome 5 appears to be fine. +

RGraph: HTML5 Javascript charts library - Bar charts documentation

+ + + +

+ Bar charts, along with Line charts, are the most configurable of all the charts available, + because they're the most common of chart types. +

+ +

+ The example file is here. +

+ + + + 
 
+<script>
+    window.onload = function ()
+    {
+        var data = [280,45,133,166,84,259,266,960,219,311];
+    
+        var bar = new RGraph.Bar('myCanvas', data);
+        bar.Set('chart.labels', ['Richard', 'Alex', 'Nick', 'Scott', 'Kjnell', 'Doug', 'Charles', 'Michelle', 'Mark', 'Alison']);
+        bar.Set('chart.gutter.left', 45);
+        bar.Set('chart.background.barcolor1', 'rgba(255,255,255,1)');
+        bar.Set('chart.background.barcolor2', 'rgba(255,255,255,1)');

+        bar.Draw();
+    }
+</script>
+
+ + +

RGraph: HTML5 Javascript charts library - Bi-polar charts documentation

+ + + +

+ Bi-polar charts are good for comparing two sets of data side by side. For example sales trends for two separate years, that you + want to compare. +

+ +

+ The example file is here. +

+ + 
+<script>
+    window.onload = function ()
+    {
+        var left  = [5,6,8,9,12,13,4,9];
+        var right = [5,8,4,11,15,26,13,16];
+    
+        var bipolar = new RGraph.Bipolar('myBipolar', left, right);
+        bipolar.Set('chart.colors', ['#fff', '#eef', '#ddf', '#ccf', '#bbf', '#bbf', '#aaf', '#99f']);
+        bipolar.Set('chart.margin', 3);
+        bipolar.Set('chart.labels', ['Barry', 'John', 'Fred', 'George', 'Rich', 'Larry', 'John', 'Mike']);

+        bipolar.Set('chart.gutter.bottom', 45);
+        bipolar.Draw();
+    }
+</script>
+

RGraph: HTML5 Javascript charts library - About canvas color definitions

+ + + +

+ You will probably want to know the different ways you can define a color. There are a few + ways which you can use, all of which are quite straight-forward. +

+ + + + +
 
+

Named colors

+ +

+ The first, and easiest, is to use named colors. This gives you a range of color values that have been predefined for you. Eg: +

+ + 
myObject.Set('chart.colors', ['red', 'blue']);
+ + +
 
+

Hex values

+ +

+ The next, is straight forward hex values like you can use in normal CSS. These consist of a hash sign, + followed by three or six hexadecimal characters. Eg: +

+ + 
myObject.Set('chart.colors', ['#f00', '#0000ff']);
+ + +
 
+

RGB values

+ +

+ Also as used in CSS, RGB values are the same as what you can use in CSS. Eg: +

+ + 
myObject.Set('chart.colors', ['rgb(255,0,0)', 'rgb(0,0,255)']);
+ + +
 
+

RGBA values

+ +

+ Probably new to most people, is rgba(). Similar to regular rgb() values, but with a fourth value that allows you to specify the + alpha value, which stipulates how transparent the color is. An alpha value of 0 is totally transparent, and a value of 1, is + totally opaque (ie. you can't see through it). With a value of 1, rgba() acts exactly like rgb(). This example gives you red + and blue colors that are semi-transparent: +

+ + 
myObject.Set('chart.colors', ['rgba(255,0,0,0.5)', 'rgba(0,0,255,0.5)']);
+ + +
 
+

HSL() values

+ +

+ Also probably quite new to you, are hsl() values. Much like rgb(), but instead of red green and blue, it allows you to specify + the Hue, Saturation and Light values instead. For example: +

+ + 
myObject.Set('chart.colors', ['hsl(255, 100%, 50%)', 'hsl(169, 100%, 50%)']);
+ + +
 
+

HSLA() values

+ +

+ Much like rgb() and rgba(), hsl() has a corresponding hsla() version, which allows you to specify an alpha (transparency) value. + Eg: +

+ + 
myObject.Set('chart.colors', ['hsla(255, 100%, 50%, 0.5)', 'hsla(169, 100%, 50%, 0.5)']);
+ + +
 
+

Linear gradients

+ +

+ Gradients can be used in place of color values. You can create a linear gradient like so: +

+ + 
myGradient = myObject.context.createLinearGradient(0,0,0,250);
+myGradient.addColorStop(0, 'red');
+myGradient.addColorStop(1, 'blue');
+ +

+ This creates a gradient that goes from red to blue. The gradient starts at 0,0, and finishes at 0,250. ie A vertical + gradient. You may not see the whole gradient - that depends on the extent of the shape you're filling. You can use the gradient + in place of a regular color definition. Eg: +

+ + 
myObject.Set('chart.colors', [myGradient]);
+ + +
 
+

Radial gradients

+ +

+ Radial gradients are much like their linear counterparts, but circular, as the name suggests. Eg: +

+ + 
myGradient = myObject.context.createRadialGradient(0,0,0,0,0,100);
+myGradient.addColorStop(0, 'red');
+myGradient.addColorStop(1, 'blue');
+
+ +

+ Instead of four arguments, it takes six - the coordinates of the start point along with the radius, and the coordinates + of the end point, along with the radius. After it has been created, you can treat as you would a linear gradient: +

+ + 
myObject.Set('chart.colors', [myGradient]);
+ + +
 
+

+ +

+ You can read more about CSS3 color definitions here. +

RGraph: HTML5 Javascript charts library - Combining charts

+ + + + + + +

Combining bar and line charts

+ + [No canvas support] + + + +

+ This is an example of combining Bar and Line charts. It's quite straight-forward, and the code here shows you how it can be achieved. +

+ +

+ If the values for the line and bar result in different Y scales you may need to specify the chart.ymax property for each chart + so that the scales are the same. The line turns off Y labels so as not to overwrite the Bars labels. +

+ + Tooltips + +

+ You can have tooltips on the Line and Bar chart by setting chart.tooltips.highlight to false, as shown. + The order in which you create the charts is also important, you must define the Bar chart first, and subsequently the Line + chart. +

+ +

Update - 28th August 2011

+

+ You can now have tooltips on both the Line chart and the Bar chart, as is shown in the chart here. Keep in mind + that you will need to have highlighting turned off on both chart types - chart.tooltips.highlight. +

+ +
+<script>
+    line.Set('chart.tooltips.highlight', false);
+    bar.Set('chart.tooltips.highlight', false);
+</script>
+
+ +

+ Because the tooltips are only triggered by the Line chart, you should put all of the information, for both the Line and the + Bar chart, in the tooltips. +

+ + +

Combining Line charts

+ + + [No canvas support] + + +

+ Another type of chart you may want is a line chart with Y axes on both sides, as illustrated on the right. You should + be careful with this chart type as it can easily lead to confusion. +

+ +

+ This chart is made up from two line charts, one with the Y axis on the left and one on the right. The code that makes up + this chart is below. +

+ +

+ The only reason to combine line charts is to get Y axes on the left and right. If you simply want mutiple lines, + you can do this without combining any charts. See the line chart example page +

+ +
+ + 
+<script>
+    window.onload = function
+    {
+        line2 = new RGraph.Line('myCanvas2', [51,22,23,33,35,23,32,45]);

RGraph: HTML5 Javascript charts library - Context menus

+ + + + + + +
+ [No canvas support]
+ (some browsers use a double left click) +
+ + + + +
 
+

What are context menus?

+ +

+ Context menus are what you see when you click your right mouse button. With RGraph, you can specify custom menus + for your charts if you wish. This way you can define custom actions to be associated with menu items. Context menus are a + very easy way to extend the functionality of your charts, allowing you to associate presentation style functionality + with them. +

+ +

+ Important: Opera does not allow you to customise the context menu, so with this browser you + should use the left mouse button on the chart, instead of the right. +

+ + +
 
+

What do they look like?

+ + An RGraph context menu + +

+ Context menus look like the image on the right. You can of course customise their look by using stylesheets. The CSS classes + you need to use are RGraph_contextmenu_background, RGraph_contextmenu and RGraph_contextmenu_item. Eg: +

+ +
+ + 
+<style type="text/css">
+    .RGraph_contextmenu {
+    }
+
+    .RGraph_contextmenu_item {
+    }
+
+    .RGraph_contextmenu_background {
+    }
+</style>
+ +

+ The "! important" is not necessary if you're not overriding a style that is set by the chart script. If you're having trouble, + it's a good idea to use it though. +

+ + +
 
+

Can I have multiple levels of menus?

+ +

+ Yes, as of 24th April 2010 you can have a dual level context menu, which can reduce "option overload" in your user interface. + This example defines a simple context menu: +

+ + 
+bar.Set('chart.contextmenu', [
+                              ['Zoom', RGraph.Zoom],
+                              ['Application', [['Login...', function () {ModalDialog.Show('modaldialog_login', 300);}]] ],
+                              null,
+                              ['Cancel', function () {}]
+                             ]);
+
+ +

+ As you can see there could easily get to be a lot of arrays, so it may help you during development to structure your code by using + indentation. +

+ + +
 
+

How do I define context menus?

+ +

+ Defining a context menu is quite a simple affair. Eg: +

+ + 
+myBar.Set('chart.contextmenu', [
+                                ['Menu item 1', Callback1],
+                                ['Menu item 2', Callback2]
+                               ]);
+ +

+ As you can see, the value is a two dimension array. The second being an array consisting of a string which is used as the name of the + menu item, and a function object (NOT the function name as a string). The function object is the function called when the menu item is selected. +

+ + +
 
+

Can I have "separators"?

+ +

+ Yes. Simply pass null instead of an array as your menu item. Eg: +

+ + 
+myBar.Set('chart.contextmenu', [
+                                ['Menu item 1', Callback1],
+                                null,
+                                ['Menu item 2', Callback2]
+                               ]);
+ + +
 
+

How do I bypass them?

+ +

+ If for any reason you wish to access the browsers own context menu, you can hold down your CTRL key on your keyboard when you + click, and the canvas context menu will be bypassed. Try it on the chart below by holding your CTRL key whilst right clicking. +

+ + + + + +
 
+ + [No canvas support] + +

How do I get the underlying shape that was clicked on?

+ +

+ In some circumstances you may want to know which bar/point/segment was right-clicked on when showing the context menu (if any). + In these cases you will find the pertinent information (the same as what you get from the various .get*() methods) on the + context menu object - which is held in the registry: RGraph.Registry.Get('chart.contextmenu').__shape__. The example bar chart + shows it in action. +

+ + 
+<script>
+    function myListener (obj)
+    {
+        p(RGraph.Registry.Get('chart.contextmenu').__shape__)
+    }
+    RGraph.AddCustomEventListener(myBar, 'oncontextmenu', myListener);
+</script>
+
+ + + +
 
+

What can I use them for?

+ +

+ Since the context menu items run Javascript functions when selected, you can use them for pretty much + anything you want. For example you could make a presentation system, with the context menu controlling which + chart is shown on the canvas, like the example above. +

+ + +
 
+

Context menus, Macs, Safari, Opera and MSIE 9

+

+ Mac Safari, Mac Firefox, Windows Safari and MSIE 9 (beta 1) can have trouble displaying the context menu. So for this reason, for these browsers, + the context menu is attached to a double click of the left mouse button. Opera doesn't support customising the context menu so + this browser also uses a left mouse button double click to trigger the context menu. +

+ + +
 
+

Related events

+

+ There are two context menu related events which you can utilise: +

+ +
    +
  • onbeforecontextmenu
    • +
  • oncontextmenu
    • +
+ +

+ As their names suggest, one fires before the contextmenu is shown, and one after. Important: Because of the + fading effect, it may seem that both events fire before the contextmenu is shown, however this is just due to the nature + of Javascript timers and the fact that alert()s will block them (pause them in effect). +

RGraph: HTML5 Javascript charts library - Available CSS classes

+ + + +

+ This is information about the CSS classes available to you to allow you to customise the appearance of tooltips and + context menus. +

+ + + + +
 
+

RGraph_png

+

+ This controls the appearance of the PNG image which is shown when you use the context menu option RGraph.showPNG(). +

+ + +
 
+

RGraph_palette

+

+ This controls the appearance of the mini-palette that can be used with annotating. +

+ + +
 
+

RGraph_tooltip

+

+ This controls the appearance of tooltips. The default is to have them look like Windows tooltips. +

+ + +
 
+

RGraph_contextmenu

+

+ This controls how context menus appear. The default is similar to the look that Windows XP has. +

+ + +
 
+

RGraph_contextmenu_item

+

+ This controls how individual items on the context menu will appear, for example the default has roughly 25px padding-left + to accomodate the left bar. +

+ + +
 
+

RGraph_contextmenu_background

+

+ This is the Windows XP style left vertical bar. By default this is light grey. +

+ + +
 
+

RGraph_zoom_window

+

+ This is the class to use if you want to customise the mini-zoom window. +

+ + +
 
+

RGraph_zoomed_canvas

+

+ This is the class to use if you want to customise the full canvas zoom. +

+ + +
 
+

RGraph_zoomed_area

+

+ This is the class to use if you want to customise the zoomed area. +

+ + +
 
+

ModalDialog_background

+

+ This class controls the dark semi-opaque background for the ModalDialog. +

+ + +
 
+

ModalDialog_dialog

+

+ This class controls the ModalDialog itself. +

+ + +
 
+

ModalDialog_topbar

+

+ This class controls the top bar for the ModalDialog. You could, for example, use the display CSS property to + hide this if you don't want it. +

+ + +
 
+

Example usage

+

+ Here is an example of using the CSS classes. At the time of writing, some of the items here were only implemented in newer + web browsers: +

+ + 
+<style>
+    .RGraph_png {
+    }
+
+    .RGraph_palette {
+    }
+
+    .RGraph_tooltip {
+    }
+    
+    .RGraph_contextmenu {
+    }
+    
+    .RGraph_contextmenu_background {
+    }
+    
+    .RGraph_contextmenu_item {
+    }
+    
+    .RGraph_zoom_window {
+    }
+    
+    .RGraph_zoomed_canvas {
+    }
+    
+    .RGraph_zoomed_area {
+    }
+    
+    .ModalDialog_background {
+    }
+    
+    .ModalDialog_dialog {
+    }
+    
+    .ModalDialog_topbar {
+    }
+</style>
+
+ + +
 
+

! important

+ +

+ If you're attempting to override default styles, then because of the ordering (ie the script is setting the style AFTER + your own CSS) you may need to use the "! important" modifier, for example: +

+ + 
+<style>
+    .RGraph_tooltip {
+        background-color: white ! important;
+    }
+</style>

RGraph: HTML5 Javascript charts library - Animation and visual effects

+ + + + + +

Introduction

+

+ The animation and visual effects code is new to RGraph as of August 2011. It greatly simplifies the process of animating your + graphs or using visual effects. +

+ + + +

Example use

+

+ To use the effects you simply change your call to the .Draw() method to the appropriate effect function, like this: +

+ + 
+<script src="RGraph.common.core.js" ></script>
+<script src="RGraph.line.js" ></script>
+<script src="RGraph.common.effects.js" ></script>
+<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" ></script>
+
+<script>
+    var myLine = new RGraph.Line('myLine', [14,13,16,18,14,12,11,14,19,18,17,18], [11,12,14,12,11,13,13,15,14,15,13,14]);
+    myLine.Set('chart.labels', ['Jane','Geoff','Lou','Pob','Verity','Baz','Hue','Olga','Pete','Lou','Kev','Fred']);
+    myLine.Set('chart.gutter.top', 35);
+    myLine.Set('chart.gutter.left', 40  );
+    myLine.Set('chart.gutter.right', 5);
+    myLine.Set('chart.gutter.bottom', 10);
+    
+    // myLine.Draw();
+    RGraph.Effects.Fade.In(myLine);
+</script>
+
+ + + +

CSS animation vs <canvas> animation

+

+ CSS animation (which jQuery does) can be smoother than canvas animation (ie changing the CSS properties vs redrawing the + canvas). This is because CSS animation (ie changing the CSS properties) does not have the side + effect of clearing the canvas, and so does not incur a redraw. +

+ +

+ An alternative to the widely known and understood setTimeout() function is the newer requestAnimationFrame(). + This is a function which has been optimised for animation compared to the standard setTimeout() function. Some of + the animation functions use this over the setTimeout() function and going forward newer animation functions will + use it. RGraph has a fallback though so that if the function isn't available the older setTimeout() will be used. +

+ + + +

Combining effects

+

+ Some of the animation effects (ie those that work on separate aspects of the chart) can be combined. As an example the + Fade in/out can be combined with most other animation effects, allowing you to add a fade effect to the other animation + types. An example of this is below - this chart uses the Grow, Fade and Reveal effects. +

+ +[No canvas support]
+ + + + 
+<script>
+    function ShowCombination(obj)
+    {
+        RGraph.Effects.Fade.In(obj);
+        RGraph.Effects.jQuery.Reveal(obj);
+        RGraph.Effects.Bar.Grow(obj);
+    }
+</script>
+<button onclick="ShowCombination(myBar)">Show Combining animations example</button>
+
+ +

+ There's another example of combined effects on the combined charts page. +

+ + +

The .Animate() function

+

+ The .Animate() function function is similar to the jQuery .Animate() function. You can pass it a map of RGraph + properties and their TARGET values and the .Animate() function will move the properties towards those values. + In this way you can animate a variety of RGraph properties. The .Animate() function takes two or three arguments: +

+ +
    +
  • The graph object
    • +
  • A map of the target chart properties
    • +
  • (Optional) A function object which is called when the animation is complete (it is passed the chart object)
    • +
+ +

An example of it use is below. It should be used instead of calling the .Draw() method:

+ + [No canvas support]
+ + + + + 
+function myCallback (obj)
+{
+    alert('A sample callback using the alert() function');
+}
+
+// myBar.Draw();
+RGraph.Effects.Animate(myBar, {'chart.hmargin': 5, 'chart.gutter.left': 50}, myCallback);
+
+ + +

Available effects

+ +

+ These are the effects available. You can achieve more effects by using the .Animate() function, + which allows you to animate any numeric RGraph property. +

+ + + + + +
+ +

Fade in

+ + [No canvas support]
+ + +

+ + A simple fade in effect where the canvas is initially drawn with an opacity of zero, increasing to one. + + 

RGraph.Effects.Fade.In(obj);
+
+ + + + + + + +
+ +

Fade out

+ + [No canvas support]
+ + +

+ + A simple fade out effect to accompany the fade in, where the canvas initially has an opacity of one, decreasing + to zero. + + 

RGraph.Effects.Fade.Out(obj);
+
+ + + + + + + +
+ +

Expand

+ + [No canvas support] +
+ + +

+ + This effect starts initially with the canvases CSS width and height set to 0 and over a period of half a second + increases them to 100%. + + 

RGraph.Effects.jQuery.Expand(obj);
+
+ + + + + + + +
+ +

Snap

+ + [No canvas support]
+ + +

+ + This effect is similar to the tooltip effect "snap" in that it "snaps" to the correct position, + moving in from the top left. + + 

RGraph.Effects.jQuery.Snap(obj);
+
+ + + + + + + +
+ +

Reveal

+ + [No canvas support]
+ + +

+ + This effect starts with the the canvas covered and is slowly revealed from the center outwards. The canvas + is at all times the same size (ie it's not resizd as with the Expand effect). + + 

RGraph.Effects.jQuery.Reveal(obj);
+
+ + + + + + + +
+ +

Horizontal Blinds (open)

+ + [No canvas support]
+ + +

+ + This effect gradually reveals the canvas by "opening some horizontal blinds", which are positioned + over the canvas. + + 

RGraph.Effects.jQuery.Blinds.Open(obj);
+
+ + + + + + + +
+ +

Horizontal Blinds (close)

+ + [No canvas support]
+ + +

+ + This effect gradually conceals the canvas by "closing some horizontal blinds", which are positioned + over the canvas. + + 

RGraph.Effects.jQuery.HBlinds.Close(obj);
+
+ + + + + + + +
+ +

Vertical Blinds (open)

+ + [No canvas support]
+ + +

+ + This effect gradually reveals the canvas by "opening some vertical blinds", which are positioned + over the canvas. + + 

RGraph.Effects.jQuery.VBlinds.Open(obj);
+
+ + + + + + + +
+ +

Vertical Blinds (Close)

+ + [No canvas support]
+ + +

+ + This effect gradually conceals the canvas by "closing some vertical blinds", which are positioned + over the canvas. + + 

RGraph.Effects.jQuery.VBlinds.Close(obj);
+
+ + + + + + + +
+ +

Pie chart Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the radius of the Pie chart, expanding out from the centre. + + 

RGraph.Effects.Pie.Grow(obj);
+
+ + + + + + + +
+ +

Pie chart Implode

+ + [No canvas support]
+ + +

+ + This effect gradually decreases the explosion of the chart - gradually bringing it together. Combined with + the RoundRobin effect (documented below) produces a nice combination, as seen on the frony page of this website. + + 

+RGraph.Effects.Pie.Implode(obj);
+//RGraph.Effects.Pie.RoundRobin(obj);
+
+
+ + + + + + + +
+ +

Pie chart RoundRobin

+ + [No canvas support]
+ + +

+ + This effect gradually increase both the circular size of the Pie chart and also the radius. Combining this effect + with the implode effect produces a nice effect. + + 

+RGraph.Effects.Pie.RoundRobin(obj);
+//RGraph.Effects.Pie.Implode(obj);
+
+
+ + + + + + + +
+ +

Bar chart Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the size of the bars on the bar chart until they are at full size. + + 

RGraph.Effects.Bar.Grow(obj);
+
+ + + + + + + +
+ +

Fuel chart Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the indicated value until it reaches the correct value. + + 

RGraph.Effects.Fuel.Grow(obj);
+
+ + + + + + + +
+ +

Slide out

+ + [No canvas support]
+ + +

+ + This effect slides the whole canvas out. One potential use would be to slide the canvas out and then + slide another canvas with a different chart in. You can specify that the canvas slides out to by using the second + argument as shown below. + + 

RGraph.Effects.jQuery.Slide.Out(obj, {'direction': 'bottom'});
+
+ + + + + + + +
+ +

Slide in

+ + [No canvas support]
+ + +

+ + This effect slides the whole canvas in. As mentioned above you could this effect with the Slinde Out effect to + create a slideshow. + + 

RGraph.Effects.jQuery.Slide.In(obj, {'direction': 'right'});
+
+ + + + + + + +
+ +

Unfold

+ + [No canvas support]
+ + +

+ + This effect "unfolds" the line from the origin, gradually increasing the X (and/or Y) values. There's also an example + of a combined Bar/Line chart with the Bar chart Grow, the Fade and the Line chart Unfold effects on the + combined charts page. + + 

RGraph.Effects.Line.Unfold(obj);
+
+ + + + + + + +
+ +

UnfoldFromCenter

+ + [No canvas support]
+ + +

+ + This effect "unfolds" the line from the center, gradually increasing or decreasing the Y values as appropriate. + + 

RGraph.Effects.Line.UnfoldFromCenter(obj);
+
+ + + + + + + +
+ +

FoldTocenter

+ + [No canvas support]
+ + +

+ + This effect "folds" the line to the center, gradually increasing or decreasing the Y values as appropriate. In + effect the opposite of the "unfold" effect. + + 

RGraph.Effects.Line.FoldToCenter(obj);
+
+ + + + + + + +
+ +

Line chart Trace

+ + [No canvas support]
+ + +

+ + This effect gradually traces the line across the chart - slowly revealing it in full. Not all Line chart options + (eg filled charts) work with this effect. + + 

RGraph.Effects.Line.jQuery.Trace(myLine14);
+
+ + + + + + + + + +
+ +

Rose chart Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the radius and the radius of each segment. It is not available with + non-equi-angular Rose charts. + + 

RGraph.Effects.Rose.Grow(obj);
+
+ + + + + + + + +
+ +

Odometer Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increase the value of the Odometer until it reaches the desired value. The second + argument is not used, but the third can be a Javascript function and will be called when the animation + is finished. + + 

RGraph.Effects.Odo.Grow(obj, null, myFunc);
+
+ + + + + + + + +
+ +

Meter Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the value of the Meter until it reaches the desired value. You can optionally specify an object map + as the second argument of which the only option is frames - allowing to specify the number of frames in the animation. + More frames = longer animation. The animation is set to use a frame rate of roughly 60 frames a second. + + 

RGraph.Effects.Meter.Grow(obj, {'frames': 90});
+
+ + + + + + + + +
+ +

HBar Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increase the values of the HBar until it reaches the desired value. + + 

RGraph.Effects.HBar.Grow(obj);
+
+ + + + + + + + +
+ +

Gauge Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the indicated value until it is correct. It's also shown on the + Gauge chart example page. By constantly updating the Gauge (with some AJAX + for example) you could make a control panel of sorts. + + 

RGraph.Effects.Gauge.Grow(obj);
+
+ + + + + + + + +
+ +

Radar Grow

+ + [No canvas support]
+ + +

+ + This effect gradually increases the magnitude of the Radar chart, growing outwards from the center. Multiple + data sets are supported. + + 

RGraph.Effects.Radar.Grow(obj);
+
+ + + + + + + + +
+ +

Waterfall Grow

+ + [No canvas support]
+ + +

+ + This effect gradually Grows the waterfall chart in both X and Y respects. + + 

RGraph.Effects.Waterfall.Grow(obj);
+
+ + + + + + + + +

Things to note

+
    +
  1. + With Fade in/out effects remember that just because you can't see the canvas (ie the opacity is 0) doesn't mean + that you can't interact with it, so tooltip hotspots will still be active. If you want to get rid of the canvas + entirely you need to remove it from the DOM. You can do this with the standard.removeNode function: + 
    obj.canvas.parentNode.removeChild(obj.canvas);
    + + This will leave a hole in the page though and will cause the page layout to change. If this is an issue you may + want to use the RGraph API function RGraph.Effects.ReplaceCanvasWithDIV(canvas). As the name + suggests, this function replaces the canvas with a DIV which has the same dimensions meaning your page structure + won't change. +
    2. + +
  2. + It should be noted that in order to prevent the canvas being constantly drawn on, it is cleared at the + start of the animation. +
    3. + +
  3. + In the jQuery animations here, the Google hosted jQuery is used: + + 
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
    +
    4. + +
  4. + Because canvas based animations may need to redraw the entire chart, + they can be slower than CSS based animations and depend on a variety of things - eg the speed of the users PC + and the work necessary to redraw the canvas. +

RGraph: HTML5 Javascript charts library - Custom RGraph events

+ + + + + + +

Introduction

+ +

+ Custom events allow you to easily interact with and extend RGraph for your own purposes. The list of available events is below, + as is an example of how to make use of them with the RGraph.AddCustomEventListener() function. Event handler functions (ie your + functions) are passed a single parameter - the chart object. With this you can get references to the canvas and context. There's + an example of this below. +

+ +
<script>
+    window.onload = function ()
+    {
+        var line = new RGraph.Line('myLine', [45,12,16,18,44,54,23,21,56]);
+        line.Set('chart.tooltips', ['Fred', 'Barney', 'Jay', 'Pete', 'Frank', 'Bob', 'Ted', 'Lou', 'Kev']);
+        line.Set('chart.labels', ['Fred', 'Barney', 'Jay', 'Pete', 'Frank', 'Bob', 'Ted', 'Lou', 'Kev']);
+        line.Set('chart.hmargin', 5);
+        line.Set('chart.tickmarks', 'dot');
+        line.Draw();
+
+        /**
+        * This is the call to the RGraph function that registers the event listener
+        * 
+        *      line: The chart object
+        * ontooltip: The name of the event
+        *    myFunc: The function that handles the event
+        */
+        RGraph.AddCustomEventListener(line, 'ontooltip', myFunc);
+    }
+
+    /**
+    * The function that is called when the ontooltip event fires. It is  passed a single parameter - the chart object.
+    * With this you can get the ID and references to the canvas and context:
+    *  o obj.id
+    *  o obj.canvas
+    *  o obj.context
+    */
+    function myFunc(obj)
+    {
+        var id      = obj.id;
+        var canvas  = obj.canvas;
+        var context = obj.context;
+
+        alert('This alert was triggered by the custom ontooltip event');
+    }
+</script>
+
+ + +

Available events

+ +

+ + [No canvas support] + ontooltip
+ This event fires immediately after a tooltip has been created. This event allows you to easily show charts in your tooltips (tooltip + effects that involve moving the tooltip, eg. contract, expand & snap, will not function). You + can find the tooltip object in the RGraph registry - RGraph.Registry.Get('chart.tooltip'). Note that if you're testing and + using a function that pauses execution (eg alert()), this will also pause any timers (for animation effects etc). If you want to + avoid this you should use a function that doesn't block execution, eg the Firebug/WebKit function, console.log() (you can use the + cl() shortcut in RGraph). +

+ +
+ +

+ + [No canvas support] + onbeforecontextmenu
+ The onbeforecontextmenu event fires before the context menu is shown. +

+ +
+ +

+ + [No canvas support] + oncontextmenu
+ This event fires immediately after the RGraph context menu is shown. If you want it, you can get at the context menu in the + RGraph registry: RGraph.Registry.Get('chart.contextmenu') + +

+ + Important: Like the ontooltip event, using alert() can + pause the fade in timers, so you might consider using the Firebug/Webkit console.log functions instead. +

+ +
+ +

+ +

+ [No canvas support]
+ +
+ + onbeforedraw
+ Much like the ondraw event, however this fires at the start of the .Draw() method, in effect "before" the method. Keep in mind + that since other charts may trigger the .Draw() method, this event can also be triggered by other charts. +

+ +
+ +

+ +

+ [No canvas support]
+ +
+ ondraw
+ The ondraw event fires after the .Draw() method has run. Note that the interactive features of RGraph may call the .Draw() + method multiple times - the zoom in area mode is a prime example. + A chart with tooltips is also an example. In this case it would demonstrate that the .Draw() method is called twice (and + hence the ondraw event), whereas the ontooltip event only fires once. + +

+ + Note: The ondraw event is not only fired by its own chart, + but (if you're using tooltips for example), can also be fired by other charts on the page. +

+ +
+ +

+ + [No canvas support] + onzoom
+ The onzoom event fires whenever the canvas is zoomed. When the zoom is in area and canvas modes this fires once, + but when in thumbnail mode this event is like the onmousemove event in that it fires whenever the mouse is moved. +

+ +
+ +

+ + [No canvas support] + onmodaldialog
+ The onmodaldialog event fires when the ModalDialog is shown. This event is easily replicated yourself, though using this event + may help you to keep your code tidy. This event is utilised slightly differently to the other events: + +
+ + 

ModalDialog.AddCustomEventListener('onmodaldialog', function () {alert('Hello world!');});
+

+ +
+ +

+ + [No canvas support] + onresizebeforedraw
+ The onresizebeforedraw event was added when translating was necessary to reclaim wasted space, before the introduction + of independent gutters. This event is now no longer necessary to reposition the resize handle. It will still have an + effect though, so if you choose to upgrade then you should remove this from your configuration. The event isn't + planned to be removed, so if you wish to use it, you can. +

+ +
+ +

+ Note: + The annotation events send notifications to the console because using alert() would cause them to lock the window. +

+ +

+ + [No canvas support] + onresizebegin
+ The onresizebegin event fires when a canvas is starting to be resized. It also fires when the canvas is reset to the original + size.

+ + onresize
+ The onresize event fires when a canvas is resized. It also fires when the canvas is reset to the original size.

+ + onresizeend
+ The onresizeend event fires when a canvas is ended resizing. It also fires when the canvas is reset to the original size. +

+ +
+ +

+ Note: + The adjusting events send notifications to the console because using alert() would cause them to lock the window. +

+ +

+ + [No canvas support] + onadjustbegin
+ The onadjustbegin event fires once at the start of an adjusting process. It can be thought of as similar to + the onmousedown event as that's when it usually fires. +

+ +
+ +

+ + onadjust
+ The onadjust event fires whenever one of the supported chart types is adjusted. It usually fires in conjunction with the + onmousemove event, and can be blocked by alert(). You therefore may need to use a different function (eg console.log()) + whilst debugging. +

+ +
+ +

+ + onadjustend
+ The onadjustend event fires once at the end of an adjusting process. It can be thought of as similar to + the onmouseup event as that's when it usually fires. +

+ +
+ +

+ Note: + The annotation events send notifications to the console because using alert() would cause them to lock the window. +

+ +

+ + [No canvas support] + onannotatebegin
+ The onannotatebegin event fires at the beginning of the annotating procedure (ie in a similar vein to the onmousedown event). +

+ +

+ + onannotate
+ The onannotate event fires when the chart has been annotated. It fires during the annotate procedure. +

+ +

+ + onannotateend
+ The onannotateend event fires at the end of the annotating procedure (ie in a similar vein to the onmouseup event). +

+ +

+ + onannotatecolor
+ The onannotatecolor event fires when the annotation color has been changed using the RGraph palette. +

+ +

+ + onannotateclear
+ The onannotateclear event fires when the RGraph annotation data has been cleared using the RGraph.ClearAnnotations() API + function. +

+ +

+ + onclear
+ The onclear event fires when the function RGraph.Clear() is called. If you use the .Clear()function inside the onclear event + handler, it will create a loop. Instead, you could use this function: +

+ + +
+ [No canvas support] + +
+ +

+ + oncrosshairs
+ The oncrosshairs event fires when the crosshairs are moved. This event is very similar to the onmousemove event, but you can + guarantee that this event fires after the crosshairs have been repainted. +

+ +
+ + 
+/**
+* This function clears the canvas
+* 
+* @param object obj The chart object
+*/
+function myClear(obj)
+{
+    obj.context.beginPath();
+    obj.context.fillStyle = 'white';
+    obj.context.fillRect(-10,-10,obj.canvas.width + 20, obj.canvas.height + 20);
+    obj.context.fill();
+}
+
+ + + +

Removing events

+

+ In the case that you need to remove RGraph event listeners, there are a few ways that you can do it. The API function + RGraph.RemoveCustomEventListener(obj, id) can be used to remove a single event listener. This function + takes the chart object and the numerical ID (returned by RGraph.AddCustomEventListener()) as its arguments. + +

+ + There's + also the RGraph.RemoveAllCustomEventListeners(), for easily removing all of the pertinent event listeners. This + function can either take no arguments at all, in which case ALL event listeners for ALL objects are removed. Or it can + also take an objects ID (the same id that you pass to the constructor), in which case the removal will be limited to + that object. +

RGraph: HTML5 Javascript charts library - Integrating RGraph with external libraries

+ + + + + + [No canvas support] + +

+ This page shows you how you can easily integrate the charts with other external Javascript libraries. This particular example + adds a context menu to the chart, of which the only option is to show a login dialog. This could, for example, be used to + allow logging in to an admin area. +

+ +

+ The dialog doesn't need to require user input - it could just be a static "Please wait..." type dialog, which is shown while a + subsequent page loads that takes a few seconds. +

+ +

+ The ModalDialog was originally an external library, however it's now part of the RGraph package. It's also covered by the + RGraph license - so if you have an RGraph license, then the ModalDialog is part of that. +

+    </div>
+<!-- End of dialog -->
+ +

+ If you're interested in using this modal dialog, then you'll probably also want the CSS that styles it. This can be found in the + "css" directory. +

+ + +

Note about Microsoft Internet Explorer 8 and the ModalDialog

+ +

+ Microsoft Internet Explorer 8 only supports fixed positioning in strict rendering mode, therefore you must specify a DTD + when using this browser. Eg: +

+ + 
+<!DOCTYPE html >
+
+ + +

Hiding the ModalDialog

+

+ To hide the ModalDialog (from a "Cancel" button for example), you can use the Close() method: +

+ + 
+<input type="reset" value="Cancel" onclick="ModalDialog.Close()">
+
+ + +

Customising the ModalDialog

+

+ You can customise the appearance of the ModalDialog by using three CSS classes, which are documented here. + This page customises the dialog slightly by changing the shadow X/Y offsets: +

+ + 
+<style>
+    /*
+    * These are the CSS classes that you can use to customise the appearance of the ModalDialog. If you're trying to
+    * override something which the scripts set, then because of the ordering you may need to use the "! important"
+    * modifier.
+    */
+    
+    /**
+    * This is the semi-opaque background
+    */
+    .ModalDialog_background {
+    }
+
+
+    /**
+    * This is the dialog itself
+    */
+    .ModalDialog_dialog {
+        -webkit-box-shadow: gray 0 0 15px ! important;
+        -moz-box-shadow: 0 0 15px gray ! important;
+        box-shadow: 0 0 15px gray ! important;
+    }
+
+
+    /**
+    * This is gray bar at the top of the dialog
+    */
+    .ModalDialog_topbar {
+    }
+</style>
+
+ + +

ModalDialog integration

+

+ To integrate the ModalDialog look at the sample code above (the key line is where the context menu is defined). The method you should call is ModalDialog.Show(id, width). + The id is the id of the layer to use. Only the .innerHTML is used, not the layer itself, so it can be hidden by + setting the display CSS display property to none. The width is a number which is used as the width of the dialog. +

+ +

+ The only library needed for the ModalDialog to work is RGraph.modaldialog.js - you do not need to use + RGraph.common.js. This makes for far smaller download requirements. +

+ + +

Covering the scroll bars

+

+ Normally, a regular DIV lives inside the browser and cannot cover the scroll bars. There is however a way to achieve + this but it does mean that restructuring your website may be necessary, and it's done by using an IFRAME. The following + steps are involved: +

+ +
    +
  1. The index page of your website creates an IFRAME and sets it to cover the entire window.
    2. +
  2. This IFRAME then loads the website.
    3. +
  3. The DIV then covers the top-most window.
    4. +
+ +

+ There is an example of this technique here +

RGraph: HTML5 Javascript charts library - Fuel Gauge documentation

+ + + +

+ The Fuel gauge is recent addition to RGraph, and the available configuration options are shown here. +

+ +

+ The example file is here. +

+ + + + 
 
+<script>
+    window.onload = function ()
+    {
+        fuel = new RGraph.Fuel('cvs', 0, 100, 67);

+        fuel.Set('chart.icon', '/images/water.jpg');
+        fuel.Draw();
+    }
+</script>
+
+ + +

Properties

+ +

+ You can use these properties to control how the Fuel Gauge apears. You can set them by using the Set() method. Eg: +

+ +

+ myFuel.Set('name', 'value'); +

+ + + +
+ +

Colors

+ + + chart.colors
+ The color of the Fuel Gauge. Noe that despite there being only one color, this is still an array.
+ Default: ['red']

+ + +

Margins

+ + + chart.gutter.left
+ The left gutter of the chart, (the gutter is where the labels and title are)).
+ Default: 5

+ + + chart.gutter.right
+ The right gutter of the chart, (the gutter is where the labels and title are).
+ Default: 5

+ + + chart.gutter.top
+ The top gutter of the chart, (the gutter is where the labels and title are).
+ Default: 5

+ + + chart.gutter.bottom
+ The bottom gutter of the chart, (the gutter is where the labels and title are).
+ Default: 5

+ + +

Needle options

+ + + chart.needle.color
+ The color of the needle (not including the bulb at the bottom). Note that this is NOT an array - it's just a string.
+ Default: 'red'

+ + +

Labels and text

+ + + chart.labels.empty
+ The label used as the empty text.
+ Default: E

+ + + chart.labels.full
+ The label used as the full text.
+ Default: F

+ + + chart.text.color
+ The color used for the text on the chart.
+ Default: F

+ + + chart.text.font
+ The font used for the text.
+ Default: Verdana

+ + +

Interactive features

+ + + chart.contextmenu
+ The context menu. For more details see here.
+ Default: null

+ + + chart.annotatable
+ Whether annotations are enabled for the chart (ie you can draw on the chart interactively.
+ Default: false

+ + + chart.annotate.color
+ If you do not allow the use of the palette, then this will be the only colour allowed for annotations.
+ Default: black

+ + + chart.resizable
+ Defaulting to false, this determines whether your chart will be resizable. Because of the numerous event handlers this has to install code on, This feature is unlikely to work with other dynamic features (the context menu is fine however).
+ Default: false

+ + + chart.resize.handle.background
+ With this you can specify the background color for the resize handle. If you're adjusting the position of the + handle then you may need this to make the handle stand out more.
+ Default: null

+ + +

Zoom

+ + + chart.zoom.mode
+ Can be used to control whether the zoom is in thumbnail or canvas mode. Possible values are: thumbnail and canvas.
+ Default: canvas

+ + + chart.zoom.factor
+ This is the factor that the chart will be zoomed by (bigger values means more zoom)
+ Default: 1.5

+ + + chart.zoom.fade.in
+ Whether the zoomed canvas fades in or not. This also can be used to control the fade in for the zoom in thumbnail mode.
+ Default: true

+ + + chart.zoom.fade.out
+ Whether the zoomed canvas fades out or not. This also can be used to control the fade in for the zoom in thumbnail mode.
+ Default: true

+ + + chart.zoom.hdir
+ The horizontal direction of the zoom. Possible values are: left, center, right
+ Default: right

+ + + chart.zoom.vdir
+ The vertical direction of the zoom. Possible values are: up, center, down

+ Default: 75

+ + + chart.zoom.thumbnail.height
+ When the zoom is in thumbnail mode, this is the height (in pixels) of the thumbnail.
+ Default: 75

+ + + chart.zoom.background
+ Defaulting to true, this determines whether the zoom has a dark, semi-opaque background that covers the entire web page.
+ Default: true

+ + + +

Miscellaneous

+ + + chart.icon
+ This should be a data: URL that represents the image to use as the icon on the chart. The + example page has an example of a chart that uses this option to show a + water droplet instead of the fuel pump.
+ Default: [A fuel icon]

Adding events to your Gantt chart

+ +

+ To add events, you specify them using the chart.events property. You could use the following to set some events on your gantt chart: +

+ + 
gantt.Set('chart.events', [
+                       [31, 28, 75, 'Richard'],
+                       [12, 28, 67, 'Fred'],
+                       [59, 14, 0, 'Barney'],
+                       [59, 21, 5, 'Gloria'],
+                       [46, 31, 94, 'Paul'],
+                       [80, 21, 46, 'Harry'],
+                       [94, 17, 84, 'Shane'],
+                       [34, 14, 32, 'Barry'],
+                       [64, 14, 28, 'Cynthia', 'red', 'yellow'],
+                       [13, 61, 74, 'Graham'],
+                       [84, 31, 16, 'Paul']
+                      ]);
+
+ +

+ The first value is the (zero indexed) start number relative to your chart.xmax. So if you have set your chart.xmax to 62, (to represent + two months), and this value is 31, the start will be the start of the second month. In this case you could give two labels - + ['July', 'August']. +

+ +

+ The second value is the duration. So using the previous example, if you set this to 7, you would have an event lasting a week. +

+ +

+ The third value is the "percentage complete" indicator. This is shown to the right of the event, and is optional - you can + specify null if you wish. +

+ +

+ The fourth value is the label that is used on the left hand side. +

+ +

+ The optional fifth value stipulates the background colour that the bar is. Default is white. +

+ +

+ The optional sixth value is the foreground color of the bar. Defaulting to #0c0. +

+ +

+ The optional seventh value is the border color, defaulting to black +

+ +

+ And the optional eigth value is the numerical linewidth of the border. The default is 1. +

+ + +

Adding vertical bars to your Gantt chart

+ +

+ You can add decorative vertical bars like so: +

+ + 
gantt.Set('chart.vbars', [
+                    [0, 31, 'rgba(192,255,192,0.5)'],
+                    [59, 31, 'rgba(192,255,192,0.5)'],
+                    [120, 31, 'rgba(192,255,192,0.5)'],
+                    [181, 31, 'rgba(192,255,192,0.5)'],
+                    [243, 30, 'rgba(192,255,192,0.5)'],
+                    [304, 30, 'rgba(192,255,192,0.5)'],
+                   ]);
+

RGraph: HTML5 Javascript charts library - Variable gutter sizes

+ + + + + + [No canvas support] + +

+ New in June 2011 is the much requested feature of seperate gutter sizing. As the chart to the right shows, this means + that you can now easily set the left/right/top/bottom gutters independently. This makes it easy to give + yourself the space that you need for labels, which will be most noticeable with the Bar chart, the Line chart + and similar chart types. There is another example on the HBar example page. +

+ +

+ Because of the fundamental nature of this change (every chart type has been affected) + you should rigorously test your charts if you choose to upgrade. +

+ +

+ The new properties are: +

+ +
    +
  • chart.gutter.left
    • +
  • chart.gutter.right
    • +
  • chart.gutter.top
    • +
  • chart.gutter.bottom
    • +
+ +

+ They all default to 25 pixels (with a few exceptions) and each can be set independently. +

+ +

+ These new properties eliminate the need for certain others. So starting immediately the following properties are no longer + used: +

+ +
    +
  • chart.gutter
    • +
  • chart.width
    • +
  • chart.height
    • +
  • chart.tooltips.coords.adjust
    • +
  • chart.resize.handle.adjust
    • +
+ +

+ The chart.gutter property has been completely removed, so you will need to start using the new properties immediately. + The chart.width and chart.height properties are completely unused from this point and the last two + will be phased out starting immediately. +

+ +
+ + 
+<script>
+        window.onload = function (e)
+        {
+            var bar = new RGraph.Bar('cvs', [0.2,0.2,0.5,0.6,0.5,0.3,0.5,0.1,0.2,0.7,4.2,3.5]);
+            bar.Set('chart.ymax', 5);
+            bar.Set('chart.labels', ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']);
+            bar.Set('chart.tooltips', ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']);

+            bar.Set('chart.contextmenu', [['Zoom in', RGraph.Zoom]]);
+            bar.Set('chart.zoom.hdir', 'left');
+            bar.Set('chart.title', '2010 statistics (tooltips)');
+            bar.Set('chart.ylabels.specific', ['100,000','10,000','1,000','100','10']);
+            bar.Set('chart.background.grid.autofit', true);
+            bar.Set('chart.background.grid.autofit.align', true);
+            bar.Set('chart.title.vpos', 0.5);
+
+            bar.Set('chart.gutter.left', 65);
+            bar.Set('chart.gutter.right', 5);
+            bar.Set('chart.gutter.bottom', 60);
+
+            bar.Draw();
+        }
+</script>
+
+ + +

Upgrading from a previous version of RGraph

+ +

+ If you're upgrading from a previous version of RGraph then there are a few points you should bear in mind: +

+ +
    +
  1. + Remove any calls to .translate(). + If you use the .translate() method to give yourself extra space, this should be converted to the new gutter properties. +
    2. + +
  2. + If you use chart.tooltips.coords.adjust or chart.resize.handle.adjust then you should remove them. These + properties will cease to have any effect eventually, but not immediately. +
    3. + +
  3. + If you use caching, then you may need to use a CTRL/SHIFT+Refresh on your page to bypass any cached copy of the RGraph + libraries. +

Methods

+ + + obj.getBar()

+ This method makes it easier to get hold of which bar has been clicked on, or hovered over. It returns an array of: +
    +
  • The X coordinate
    • +
  • The Y coordinate
    • +
  • The width of the bar
    • +
  • The height of the bar
    • +
  • The numerical index of the bar. This corresponds (for example) to the tooltips array, and the coordinates array

RGraph: HTML5 Javascript charts library - Horizontal Progress bar documentation

+ + + +

+ The example file is here. +

+ + 
+<script>
+    window.onload = function ()
+    {
+        var myProgress = new RGraph.HProgress('myProgress', 78, 100);    
+        myProgress.Set('chart.colors', ['red']);
+        myProgress.Draw();
+    }
+</script>
+
+ +

Properties

+ +

+ You can use these properties to control how the progress bar apears. You can set them by using the Set() method. Eg: +

Default: null

+ +chart.title.vpos
+ This allows you to completely override the vertical positioning of the title. It should be a number between 0 and 1, and is multiplied with the gutter and then used as the vertical position. It can be useful if you need to have a large gutter.

+ +chart.annotate.color
+ If you do not allow the use of the palette, then this will be the only colour allowed for annotations.
Default: black

+ + + + chart.resizable
+ Defaulting to false, this determines whether your chart will be resizable. Because of the numerous event handlers this has to install code on, This feature is unlikely to work with other dynamic features (the context menu is fine however).
+ Default: false

+ + + + chart.resize.handle.background
+ With this you can specify the background color for the resize handle. If you're adjusting the position of the + handle then you may need this to make the handle stand out more.

Benefits of RGraph: HTML5 Javascript charts library

+ +

+ The HTML5 canvas tag is a new tag for HTML5. It allows for two dimensional drawing easily using Javascript. + This makes it perfect for producing charts. Because Javascript runs on your users' computer, none of the load on your web server + normally associated with producing charts is incurred. Not only that but because + of the greater processing power that is typically available on users' computers, they will be much faster. And, + because the code can be both compressed (for example if you're using Apache, mod_gzip will do this automatically for you) and + cached, bandwidth usage can be massively reduced. This makes it economically attractive to employ at the same time as + benefiting your website, ie: +

+ +
    +
  • It can save you money by reducing the load on your web server(s)

    • +
  • It can speed up your web pages
    • +
+ +

+ Imagine, you are creating 10,000 charts a day and the data is such that the resulting charts cannot be cached. With the RGraph + library you can reduce that figure to zero. All the processing is done by each individual web browser, much like + showing the HTML that you send to them. So you don't have to send any images, you simply send them the Javascript charts libraries + once. So, much lower bandwidth bills and less strain on your webserver. +

+ +

+ And if that wasn't enough, because the charts are created using Javascript, they will work offline if you view a .html page + on your own PC. Download the archive and see! Useful if you need to do a presentation (for example) and want to use the same + charts as your website. +

+ +
+
+
    +
  • Cross browser support.
    • +
  • 20+ Different base chart types (Examples).
    • +
  • Charts work on and off-line.
    • +
  • Interactive features.
    • +
+
+ +
+
    +
  • Charts are created on the client - no server overhead.
    • +
  • Very easy setup (see Implementing RGraph).
    • +
  • Fully documented.
    • +
  • Very easy to learn.
    • +
+
+
+ + + +
 
 
+

Browser support

+ +

+ Since the charts are produced using HTML5 features (the new canvas tag), client support includes: +

+ +
    +
  • Mozilla Firefox 3.0+
    • +
  • Google Chrome 1+
    • +
  • Apple Safari 3+
    • +
  • Opera 9.5+
    • +
  • Microsoft Internet Explorer 8+ (see note)
    • +
  • iPhone (text support from iOS v4+)
    • +
  • iPad (text support from iOS v4.2+)
    • +
+ +

+ The HTML5 canvas tag is part of the HTML5 specification, + and all of the above browsers have some sort of support for it. +

+ +

+ HTML5 canvas & Microsoft Internet Explorer (MSIE)
+ Microsoft Internet Explorer 8 doesn't natively support the HTML5 canvas tag. To support + MSIE8 you will need to use either + Google Chrome Frame or + ExCanvas from Google + (which is included in the RGraph archive). Read more about Internet Explorer compatibility + here. + +

+ + + Starting from the developer preview 3, Microsoft Internet Explorer 9 has full support for + HTML5 canvas. + MSIE 6 and 7 are supported by way of Google Chrome Frame. + +

+ +

+ RGraph and older browsers
+ Older browsers (eg Chrome 1, Firefox 3, Safari 3, Opera 9.5) are supported, however if they don't support the canvas shadow or + text APIs, these will naturally be unavailable. Earlier versions of these browsers may work, but are untested. +

+ +

+ Other devices
+ Other devices (eg mobile devices) may support or may be intending to support the HTML5 CANVAS tag as part of their HTML5 support. Typically + the newer a device or its OS the higher the likelyhood is that it has support for HTML5 canvas. +

+ + +
 
 
+

Improving the performance of your charts

+ +

+ Although performance is excellent, (eg compared to server based charts libraries), you may still want to tune + RGraph further. The biggest thing you can do is use HTTP compression, which reduces the initial download time of the libraries, + but there are a number of things you can do: +

+ +
    +
  • + Compression
    HTTP compression can dramatically reduce your bandwidth bills and increase the speed + of your website. The RGraph.common.core.js file for example used to be over 100k, but with compression this was reduced + to around 17k. Less than a fifth of the original size! If you do only one thing to aid performance, + then it should be this. + +

    + To achieve this with Apache you have a few options: +

    + +
      +
    • You can use the Apache module mod_gzip which compresses the libraries on the fly.
      • +
    • + You can compress the libraries manually using the Unix gzip command, rename them to remove the .gz suffix + and add the header using an Apache directive + (eg AddEncoding gzip .js). If you have some sort of + release process/script, it would make sense to add this to it to automate the procedure. +
      • +
    +

    +

    • + +
  • + Minification
    + Minification reduces the size of the library before compression takes effect, removing unnecessary spaces and comments etc. + A combination of minification and compression will give superb results. For example, before being split up into seperate files, + minification combined with compression reduced the common library from over 100k to roughly 10k (!). There is a PHP shell + script that you can use to minify the libraries in the scripts directory. + +

    + You can get pre-minified versions of the libraries here. +

    +
    • + +

    + +

  • + Pre-emptive caching
    + Slightly different to caching itself, is pre-emptive caching. This involves downloading the libraries before the page that requires + them is shown. This way, they're already in the users browser cache and the chart will subsequently appear to be much much + quicker. An example of this would be having the library included at the bottom of your index page of your website (optionally + with the defer="defer" attribute). The script can be downloaded at will because the page doesn't actually use it, but + for subsequent pages it will already be in the users browser cache. + +

    +

    • + +
  • + Caching
    + Since the libraries you're using won't change that often, you can set distant Expires: headers on them, or appropriate + Cache-Control: headers, and the client will not even have to contact your server for it. When you want to make sure + the library is re-downloaded (eg. you update the library), then simply change the filename. + +

    +

    • + +
  • + Script tag placement
    + According to Yahoo! guidelines placing the <SCRIPT> + tag at the bottom of the page can increase the percieved load time. If you do this, then your charts should be + created in the window.onload event, otherwise the browser may try to create them without the library + having been loaded, and will therefore subsequently fail. + +

    + + You should also consider the effect that this has when your page is rather weighty. If the page is weighty there + will be a small delay before the onload event fires, and therefore creates the chart. This might not be so bad if the + chart is not immediately visible, however if it is then you should carefully consider using the onload event. You + may wish to load the library in the page header, define the canvas tag and then immediately define the javascript + that creates the chart. This way + the chart will be created and shown, and then the rest of the page loads. The end result is that your chart + appears to be faster. + +

    + + Between the onload event, asychronous Javascript and careful tag placement, you will need to experiment to get the right result + for you. +

    • + +
  • + Document structure
    + The structure of your document can have a significant impact on how fast your charts are displayed. If, for example, you use + tables for layout, this can delay the display of elements that are affected by the size of the table. Where possible, you + should consider trying to convert your layout to DIVs. An example of this is the front page of this website. The charts + were right aligned using a table as a container. This caused a visible delay when showing them. In this case it was a + simple matter to convert the page to use DIVs, and the page subsequently displays much faster. +

    +

    • + +
  • + Creating your charts asynchronously
    + Where possible, you may wish to create your charts asynchronously. This allows the browser to continue rendering the page + immediately after getting to the code that creates the chart. This might not be perceptible if you don't have a lot of + charts, or your page is small. You can read a little more about this and see example code here. + +

    + + Note that recent releases of Google Chrome (from a dev release of version 4) have had an issue with creating charts + asynchronously, which presents itself by not drawing text sometimes (it's not consistent). Simply not using + asynchronous chart production in this case resolves the issue. +

    • + +
  • + DOMContentLoaded event
    + Using this event can speed up the display of your charts signifcantly compared to the more well known onload event. + It is supported by Chrome, Gecko based browsers (ie Firefox), Safari, Opera and Internet Explorer 9. This event fires when + the structure of the page is loaded, but not necessarily the images or CSS. This means that if your page is laden with + images, this event will fire before the onload event, thus creating your charts quicker. The effect can be very noticeable. + + 
    +function addListener(func)
+{
+    if(window.addEventListener) {
+        window.addEventListener('DOMContentLoaded', func, false);
+    } else {
+        document.attachEvent("onDOMContentLoaded", func);
+    }
+}
+
    + You can read more about the DOMContentLoaded event on the Mozilla site, here, + and the Microsoft site here. + There's an example here. +

    +

    • + +
  • + AJAX requests
    + If you can take advantage of AJAX, you can use this method to retrieve data from your server. If, for example, you have a chart that + shows ongoing information, instead of simply refreshing the entire page, you could use an AJAX request to just retrieve the + data that you want and update the chart that way. This reduces the amount of data needed to be transferred, thus reducing the + bandwidth used, and will be quicker than a full page refresh, particularly if your page is weighty. There's a simple AJAX + function that you can use below. +

    +

    • + +
  • + Combining libraries
    + You may wish to consider combining the RGraph libraries into a single file. + This won't save on the size of the individual libraries, but will save on the headers that are sent as part of the response. + If a typical response sends 500 bytes worth of headers, and you send four chart libraries, then combining the libraries + would save 1500 bytes. Multiple factors need to be considered though, including things like caching, which can circumvent + the unneccessary repeated downloading of the libraries. + +

    + To make your life straight-forward, you may want to make this a part of your release script/process. This way you + can make changes to the scripts in your development environment as you would normally. +

    + +

    + Another effect of combining libraries is reducing the amount of HTTP connections needed to retrieve them. Most browsers + have a limit on how many connections they can create simultaneously, so if they're not being used to retrieve your + chart libraries, they can be used for something else. +

    +
    • + +
  • + Avoiding shadow blur with animations
    + If you're using animations then you may wish to avoid or reduce the shadow blur that you're using. With HTML5 canvas shadow + blur is a drain on performance - so if you're looking to get the most out of your charts or are using animations + which require redrawing the chart, turning off the shadow blur can reduce the time it takes to draw the charts leading to + smoother charts. +
    • +
+ + A reasonable performance strategy + +

+ Although there's a lot you can do in regards to performance, a few of the points here will suffice for most + websites: + +

    +
  • Compression
    • +
  • Minification
    • +
  • Pre-emptive caching
    • +
  • Caching
    • +
+ + The number one thing you should do is compress your libraries. This has multiple benefits and provides by far the most gain, + effectively for free. Secondly, use the minified libraries. Since you can download them here, + you might as well use them. Then we have pre-emptive caching. Since most websites won't show charts on the front page or will + have a login page that is shown before any charts, this effectively eliminates the charts library download. And lastly caching + should be done as a matter of course. There's no reason to keep downloading the same library so even caching for only 30 minutes + (or the duration of an average visit to your website) will produce results. +

+ +

Implementing RGraph

+ +

+ Getting RGraph up and running is very easy and consists of three steps. If you're having trouble I suggest you get hold of a copy of + Firefox along with Firebug - its + Javascript error console will make debugging your issue much easier. Many problems are down to a library not having been included or + not using the onload event when you need to. You might also benefit from using the Web Developer toolbar + for Firefox. This allows you to easily disable caching, thus eliminating any problems that that causes. You could equally use + the Chrome developer tools (CTRL+SHIFT+J), optionally in docked mode, which also provides a good quality Javascript console. +

+ +
    +
  1. + Include the libraries (put this in your documents <HEAD>): +
    +<script src="RGraph.common.core.js"></script>
+
+<script src="RGraph.common.adjusting.js"></script> <!-- Just needed for adjusting -->
+<script src="RGraph.common.annotate.js"></script>  <!-- Just needed for annotating -->

+<script src="RGraph.waterfall.js"></script>        <!-- Just needed for waterfall charts  -->
+
    +
    2. + +
  2. + Add the canvas tag (put it where you want the chart to appear): +
    +<canvas id="myCanvas" width="600" height="250">[No canvas support]</canvas>
+
    +
    3. + +
  3. + Create the chart (since it is using the onload event, you can put this anywhere): + +
    +<script>
+    window.onload = function ()
+    {
+        var data = [280, 45, 133, 166, 84, 259, 266, 960, 219, 311, 67, 89];
+
+        var bar = new RGraph.Bar('myCanvas', data);
+        bar.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+        bar.Set('chart.gutter.left', 35);
+        bar.Draw();
+    }
+</script>
+
    +
    4. +
+ +

+ There's also a very basic example of using RGraph, that does very little. It can be helpful to + illustrate how you can get RGraph up and running. +

+ + +
 
 
+

Suggested structure for RGraph

+ + Suggested structure for RGraph + +

+ The suggested layout structure for the RGraph libraries is shown on the right. The www.example.com folder represents + the root/top level of your website with the javascript directory beneath that. The css and images + folders are shown for + illustrative purposes only. If you follow this layout then your URLs to the RGraph libraries would be: +

+ +

+ http://www.example.com/javascript/rgraph/RGraph.common.core.js
+ http://www.example.com/javascript/rgraph/RGraph.bar.js
+ etc +

+ +

+ By using this structure you make RGraph easy to update should you need to, and also keep all the RGraph libraries in + one, easy to find, place. +

+ +
+ + +
 
 
+

Integration with server side scripting

+ +

+ This is a very easy process, as easy as sending content to the browser. All you need to do is make the data variable + (as in the example below) contain the data you want to be displayed. Eg: +

+ + 
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>
+
+<canvas id="myCanvasTag" width="600" height="200">[No canvas support]</canvas>
+
+<script>
+    data = [78,16,26,23,25,51,34,64,84,84];
+
+    line = new RGraph.Line("myCanvasTag", data);
+    line.Set("chart.labels", ["Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov"]);
+    line.Draw();
+</script>
+
+ +

+ To get the above using PHP you could do this: +

+ + 
<?php
+    // This simply makes a string out of the array of data
+    $myData = join(',', array(78,16,26,23,25,51,34,64,84,84));
+
+    // This prints out the required HTML markup
+    print('<script src="RGraph.common.core.js"></script>' . "\n");
+    print('<script src="RGraph.line.js"></script>' . "\n\n");
+    print('<canvas id="myCanvasTag" width="600" height="200">[No canvas support]</canvas>' . "\n\n");
+    print('<script>' . "\n");
+    print('    var data = [' . $myData . '];' . "\n\n");
+    print('    var line = new RGraph.Line("myCanvasTag", data);' . "\n");
+    print('    line.Set("chart.labels", ["Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov"]);' . "\n");
+    print('    line.Draw();' . "\n");
+    print('</script>');
+?>
+
+ +

+ Strictly speaking the var isn't necessary, however if you put the code inside a + function (like window.onload), it's probably best to do so as using var will + make the variable local, and not global. So doing so will help prevent naming clashes. +

+ + + +
 
 
+

Integration with PHP & MySQL

+ +

+ This is a simple matter of formatting what you get back from MySQL into a string, as the MySQL dump and PHP code + below shows (it's based on a database called RGraph_example): +

+ + 
+#
+# Table structure for table `daily_statistics`
+#
+
+CREATE TABLE `daily_statistics` (
+  `st_day` char(9) NOT NULL,
+  `st_statistics` tinyint(4) NOT NULL,
+  UNIQUE KEY `st_day` (`st_day`)
+) ENGINE=MyISAM DEFAULT CHARSET=latin1;
+
+#
+# Dumping data for table `daily_statistics`
+#
+
+INSERT INTO `daily_statistics` VALUES ('Mon', 124);
+INSERT INTO `daily_statistics` VALUES ('Tue', 95);
+INSERT INTO `daily_statistics` VALUES ('Wed', 64);
+INSERT INTO `daily_statistics` VALUES ('Thu', 94);
+INSERT INTO `daily_statistics` VALUES ('Fri', 75);
+INSERT INTO `daily_statistics` VALUES ('Sat', 98);
+INSERT INTO `daily_statistics` VALUES ('Sun', 84);
+
+ + 
+<?php
+    /**
+    * Change these to your own credentials
+    */
+    $hostname = "localhost";
+    $username = "root";
+    $password = "PASSWORD";
+    $database = "RGraph_example";
+    
+    $connection = mysql_connect($hostname, $username, $password) OR die('Could not connect to MySQL: ' . mysql_error());
+    mysql_select_db($database);
+    
+    $result = mysql_query("SELECT st_day, st_statistics FROM daily_statistics");
+    if ($result) {
+    
+        $labels = array();
+        $data   = array();
+    
+        while ($row = mysql_fetch_assoc($result)) {
+            $labels[] = $row["st_day"];
+            $data[]   = $row["st_statistics"];
+        }
+
+        // Now you can aggregate all the data into one string
+        $data_string = "[" . join(", ", $data) . "]";
+        $labels_string = "['" . join("', '", $labels) . "']";
+    } else {
+        print('MySQL query failed with error: ' . mysql_error());
+    }
+?>
+<html>
+<head>
+
+    <!-- Don't forget to update these paths -->
+
+    <script src="libraries/RGraph.common.core.js" ></script>
+    <script src="libraries/RGraph.line.js" ></script>
+
+</head>
+<body>
+    
+    <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
+    <script>
+        chart = new RGraph.Line('cvs', <?php print($data_string) ?>);
+        chart.Set('chart.background.grid.autofit', true);
+        chart.Set('chart.gutter.left', 35);
+        chart.Set('chart.gutter.right', 5);
+        chart.Set('chart.hmargin', 10);
+        chart.Set('chart.tickmarks', 'endcircle');
+        chart.Set('chart.labels', <?php print($labels_string) ?>);        
+        chart.Draw();
+    </script>
+
+</body>
+</html>
+
+ +

+ This PHP code provides the data in two strings - $labels_string and $data_string. These variables are then used + in the RGraph code to provide the data and the labels. +

+ +

Remember:

+ +
    +
  • Change the database hostname/username/password/database to match your own.
    • +
  • Ensure you have the correct paths to the RGraph libraries.
    • +
+ + +
 
 
+

Making AJAX requests

+ +

+ Note: + It is important that you're careful with types when making AJAX requests. Since the response is initially a string, + and your AJAX function/library may not do conversions for you, you may need to convert these strings to numbers. To + do this you can use the Number() or parseInt() functions. For example: +

+ + 
+<script>
+    num = Number('23');
+    num = parseInt('43');
+</script>
+
+ +

+ Here is a simple function that you could use to get data from your server using AJAX: +

+ + 
+<script>
+    /**
+    * Makes an AJAX call. It calls the given callback (a function) when ready
+    * 
+    * @param string   url      The URL to retrieve
+    * @param function callback A function object that is called when the response is ready, there's an example below
+    *                          called "myCallback".
+    */
+    function AjaxCall (url, callback)
+    {
+        // Mozilla, Safari, ...
+        if (window.XMLHttpRequest) {
+            var httpRequest = new XMLHttpRequest();
+        
+        // MSIE
+        } else if (window.ActiveXObject) {
+            var httpRequest = new ActiveXObject("Microsoft.XMLHTTP");
+        }
+        
+        httpRequest.onreadystatechange = callback;
+        
+        httpRequest.open('GET', url, true);
+        httpRequest.send();
+    }
+
+
+    /**
+    * This sample callback function is called when the data is ready (readyState=4)
+    */
+    function myCallback ()
+    {
+        if (this.readyState == 4 && this.status == 200) {
+            // Everything is good, the response is received
+            alert(this.responseText);
+        }
+    }
+</script>
+
+ +

And you would use it like this:

+ + 
+<script>
+    AjaxCall('http://www.example.com/getSomething.php', myCallback);
+</script>
+
+ +

+ There's an example here that shows updating your chart dynamically. +

+ + + +

RGraph: HTML5 Javascript charts library - In-graph labels

+ + + +
+ +

+ This page shows the various options for in-graph labels. The in-graph labels can be set like this: +

+ + 
obj.Set('chart.labels.ingraph', [,,'Hoolio',,'Olga']);
+ +

+ Or like this if you want to be more specific: +

+ + 
obj.Set('chart.labels.ingraph', [,,['Hoolio', 'red', 'yellow', -1, 60],,'Olga']);
+ +

+ The array can consist of: +

+ +
    +
  • The label text
    • +
  • The text color
    • +
  • The background color
    • +
  • This can be 1 or -1 and denotes whether the label should be above or below the line. This has no effect in Bar or Scatter charts
    • +
  • The length of the label pointer/arrow
    • +

RGraph: HTML5 Javascript charts library - Common issues

+ + + +

+ These are some common issues that you should be aware of. If you're having trouble, you may want to look through these to see + if any apply to you or may be the source of your problem. +

+ + + +

Annotations aren't saved when running locally in Mozilla Firefox

+ +

+ The solution here is to run the charts using a web server. At this time (March 2010) only Safari, Chrome and Opera + support saving annotations when running locally. +

+ + +

Missing text in Google Chrome

+ +

+ Since one of the Chrome 4 dev releases there has been an issue with Google Chrome 4 and 5, asynchronous processing and not rendering + chart labels. This has been remedied by simply not using asynchronous processing. Because of the tag placement on the front page, + the effect shouldn't be apparent. Other browsers (eg Firefox, Safari, Opera, MSIE) are fine. +

+ +

+ Update: Currently, (roughly March 2011), the missing text issue appears to be much less evident, if not resolved entirely. +

+ + +

Firefox, tooltips and the clipboard

+ +

+ Firefox, tooltips and using the clipboard is a little convoluted. To copy the text in a tooltip you must do the following: +

+ +
    +
  1. Select the text you want with the mouse.
    2. +
  2. Press CTRL+C (it may be a different key combination if you're not using Windows) to copy the text to the clipboard.
    3. +
+ +

+ Note: Recent versions of Firefox 4 (from beta 6 onwards) appear to work as expected, and you can copy text with the mouse as normal. +

+ +

Shadows in Google Chrome and the line chart

+ +

+ Shadows in recent versions of Google Chrome are somewhat broken. Firefox, MSIE, Opera and Safari are fine. The reason for this + error is a combination of factors it seems - shadow blurring and line width. Fixes have been added to allow shadow blurring and + a 1 pixel linewidth, though some chart types may still be affected. +

+ As of 4th December 2010 the code that produces the keys has been rewritten. There are two variants of keys available, + a horizontal one designed to sit in the gutter, and a vertical one that is designed to sit on top of (ie over) the chart. +

+ +

+ The actual positioning is now configurable though, so you could have a horizontal key and position it to sit on top + of the chart. +

+ +

Key properties

+ +

+ The available key properties and their defaults are listed below (some chart types have slightly different defaults to + suit): +

+ + +
    +
  • chart.key ([] (An empty array))
    • +
  • chart.key.position (graph)
    • +
  • chart.key.position.gutter.boxed (true)
    • +
  • chart.key.position.x (null)
    • +
  • chart.key.position.y (null)
    • +
  • chart.key.shadow (false)
    • +
  • chart.key.shadow.offsetx (2)
    • +
  • chart.key.shadow.offsety (2)
    • +
  • chart.key.shadow.color (#666)
    • +
  • chart.key.shadow.blur (3)
    • +
  • chart.key.color.shape (square)
    • +
  • chart.key.background (white)
    • +
  • chart.key.rounded (true)
    • +
  • chart.key.text.size (10)
    • +
+ +

Interactive keys

+

+ The Line chart supports interactive keys - as shown in the example. This is only available when the key + is in graph mode. This allows you to click a key item and it will be highlighted on the chart. +

RGraph: HTML5 Javascript charts library - LED Grid documentation

+ + + +

+ The LED grid can be used to represent simple letters and numbers. +

+ +

+ The example file is here. +

+ + 
+<script>
+    window.onload = function ()
+    {
+        var led = new RGraph.LED('myCanvas', '456461');
+        led.Set('chart.dark', '#666');

RGraph: HTML5 Javascript charts library - The RGraph license

+ +

+ There are two license types available with RGraph - a free one for non-commercial entities and a non-free commercial use license. + Each is described below. +

+ + + + + + +  

+

An overview of the licensing

+

+ A overview of the licensing is that for commercial use there is a one-time licensing fee of £79 (GBP) + whilst for non-commercial use (eg personal, government, charity, educational etc) it's free + to use assuming that you link to www.rgraph.net on your website. +

+ + +  

+

Commercial usage

+ +
+
+ + + + + + + +
+ +
+ + + + +
+
+ +

+ Commercial usage covers commercial entities for their websites + (either internal or external) or in software that they produce. If your organisation generates + profit then a commercial license is most appropriate. There are some FAQs below that + should help to answer any questions that you may have, but if they don't then you can + email your question to: support@rgraph.net +

+ +

+ After completion of either Google Checkout or Paypal payment you are granted an RGraph commercial license. You will + be sent the license details via email. +

+ +

+ Example uses are: + +

    +
  • Internal websites (eg intranets)
    • +
  • Private websites
    • +
  • Public facing websites
    • +
  • Online applications
    • +
  • Offline applications
    • +
+ + + You may alter the RGraph code to suit your particular needs. Also, if you're covered by the non-commercial license, however + you don't wish to link to the RGraph website then buying a commercial license means that you dont have to. +

+ + +  

+

Commercial license FAQs

+ + + +

+ +  


+ Do I need to buy a commercial license?
+ For commercial/business use, then yes - you need a license to use RGraph. + +

+ + +  


+ How much is a license?
+ A license is a fee of £79 (UK pounds). That's a little over $120 (US dollars) at + the time of writing. + +

+ + +  


+ What if I need something that's not part of RGraph?
+ If there's a feature that you need that's not part of RGraph then I can usually accommodate you assuming that + you're a license holder. Please contact support first to discuss your needs. If it's not too specific to you then + I can add it to the main RGraph software. If it is then I can add it to your specific copy of RGraph. You can + contact support with support@rgraph.net + +

+ + +  


+ What does the license cover?
+ The RGraph license covers RGraph as a whole. Excepting ExCanvas, all code that you find in the RGraph archive is + covered by the RGraph license. + +

+ + +  


+ What if I'm a web designer?
+ In this situation each client would need a separate license for themselves. They can then use RGraph as much as they wish. + If you prefer to buy in bulk - discounts are available (see next question). + +

+ + +  


+ Is there a discount for buying licenses in bulk?
+ Yes there's a discount available if you wish to buy 5, 10 or 15 licenses (you could be a web designer for example + wishing to license your clients). Please contact support if this interests you. + +

+ + +  


+ Do I need to provide a backlink?
+ Commercial license holders do not need to provide a backlink to the RGraph website. + +

+ + +  


+ Can you send me an invoice?
+ Of course, simply go here: http://www.rgraph.net/invoice.html, enter your email + address and you'll be sent an invoice that you can use for tax purposes. +

+ + +  

+

Non-commercial free usage

+

+ RGraph can be used free-of-charge by non-commercial entities who wish to use it either on an internal or external website + or in software that they make. Examples of non-commercial entities include: + +

    +
  • Individuals
    • +
  • Charities
    • +
  • Government bodies
    • +
  • Educational institutes
    • +
+ + Attribute RGraph on your website by linking back to the RGraph site - example HTML code as follows: +

+ + 
+<a href="http://www.rgraph.net" target="_blank">
+    Charts made with RGraph: HTML5 Javascript charts library
+</a>
+
+ +

+ If you would prefer not to link to the RGraph website, then you can buy an RGraph commercial license and you won't need to. + You may alter the RGraph code to suit your particular needs. +

+ + +
+
+ + + + +
+
+ +

+ If you're covered by the free license but want to make a donation to help keep RGraph going then they're all gratefully + received. You can use PayPal button on the left to send it. Thanks! +

RGraph: HTML5 Javascript charts library - Line charts documentation

+ + + +
+ Note: + With the Line chart, there isn't an option to have a scale on the X axis. For this you'll need a Scatter chart with + chart.line set to true. +
+ +

+ Line charts, along with Bar charts, are probably the most configurable of all the charts available. +

+ +

+ The example file is here. +

+ + + + 
+<script>
+    window.onload = function ()
+    {
+        var data = [10,4,17,50,25,19,20,25,30,29,30,29];
+    
+        var line = new RGraph.Line("myLine", data);
+        line.Set('chart.background.barcolor1', 'rgba(255,255,255,1)');
+        line.Set('chart.background.barcolor2', 'rgba(255,255,255,1)');
+        line.Set('chart.background.grid.color', 'rgba(238,238,238,1)');
+        line.Set('chart.colors', ['rgba(255,0,0,1)']);
+        line.Set('chart.linewidth', 2);
+        line.Set('chart.filled', true);
+        line.Set('chart.hmargin', 5);
+        line.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+        line.Set('chart.gutter.left', 40);
+        line.Draw();
+    }
+</script>
+
+ + +

+ When using autofit this allows you to specify how many vertical grid lines you want.
+ Default: 20

+ + + chart.background.grid.autofit.align
+ If you want to have your grid lines line up with the labels (both X and Y axes), you can set this to true and RGraph will + attempt to make the grid lines line up. If you have a chart.hmargin set then the alignment will be thrown out.

+ A value (1, 3, 5 or 10) that controls how many Y labels there are.
+ Default: 5

+ + +chart.ylabels.inside
+ This controls whether the Y labels are drawn inside the Y axis or not. If your labels are large, this may help.
Default: false

+ +chart.ylabels.inside.color
+ If the Y labels are to be drawn inside the Y axis, this is used as the background color.

+ Default: false

+ + +

Scale

+ + + chart.scale.formatter
+ To allow thoroughly custom formats of numbers in the scale, you can use this option to + specify a function that is used by RGraph to format numbers. This function should + handle ALL of the formatting. Eg:

+ 
+function myFormatter(obj, num)
+{
+    return num + 'F'; // An example of formatting
+}
+myGraph.Set('chart.scale.formatter', myFormatter);

Miscellaneous

+ + + chart.tickmarks
+ What kind of tickmarks to use on the chart. This can be:
  • dot
  • circle
  • filledcircle
  • endcircle
  • square
  • endsquare
  • filledsquare
  • filledendsquare
  • tick
  • halftick
  • endtick
  • cross
  • borderedcircle (same as dot)
  • arrow
  • filledarrow

Note that "arrow" and "filledarrow" look better with a thinner (1 or 2) linewidth setting. Also note that now (10th August 2010) as well as a string, this can be an array of different tickmark styles.
+ Default: null

+ + + chart.tickmarks.dot.color
+ This is the color of the BORDER around the dot/borderedcircle style tickmarks.
+ Default: #fff

+ + + chart.tickmarks.linewidth
+ This is the width of the line used when drawing the tickmarks. By default this is the same as the chart.linewidth setting.
+ Default: null

+ + + chart.stepped
+ Draws the line as stepped. Useful for showing stock performance for example.
+ Default: false

+ + + chart.linewidth
+ The width of the line (ie the actual line on the chart). Note: If your line is stepped and filled, and you don't want a trailing line indicating the last value, you can set this to zero.
+ Default: 1

+ + + chart.variant
+ At present this can only be 3d, and gives a small 3D effect.
+ Default: null

+ + + chart.animation.unfold.x
+ This is used by the Unfold Line chart animation and dictates whether the X value is unfolded.

+ Default: 2 + +

+ + chart.chromefix
+ Since version 6, Chrome has had a shadow bug, which becomes apparent when you use shadow blurring. This value defaults + to true and means that RGraph will skirt the bug with a small fix.
Default: true

+ + + chart.highlight.stroke
+ If you use tooltips, this controls the colour of the highlight stroke. +
Default: black

+ + + chart.highlight.fill
+ If you use tooltips, this controls the colour of the highlight fill. +
Default: rgba(255,255,255,0.5)

+ + + chart.curvy
+ If you prefer - this draws a more cuvy chart. Because of the curves these charts are not exact, and the inaccuracy increases + with a greater curve factor (controlled by the next property). Being new, this property may not work with all the line chart features + and should be used with caution. +
Default: false

+ + + chart.curvy.factor
+ This controls the severity of the curves when the above property is used. It can be a decimal from 0 (not curvy at all) + to 0.5 (quite curvy). +
Default: 0.25

+ + +

+ + + +

Methods

+ + + obj.getPoint(e)

+ This method makes it easier to get hold of which point on the Line chart has been hovered over. It returns an array of: + +
    +
  • The chart object
    • +
  • The X coordinate
    • +
  • The Y coordinate
    • +
  • The numerical index of the point. This corresponds (for example) to the tooltips array, and the coordinates array
    • +
+ + An example usage is: + + 
+<canvas id="cvs" width="600" height="300">[No canvas support]</canvas>
+
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>
+
+<script>
+    myGraph = new RGraph.Line('cvs', [10,4,2,4,1]);
+    myGraph.Set('chart.hmargin', 10);
+    myGraph.Set('chart.tickmarks', 'endcircle');
+    myGraph.Set('chart.labels', ['Fred','John','Kev','Lou','Pete']);
+    myGraph.Draw();
+
+
+    RGraph.Register(myGraph);
+    
+    myGraph.canvas.onmousemove = function (e)
+    {
+        RGraph.FixEventObject(e);
+
+        var canvas  = e.target;
+        var context = canvas.getContext('2d');
+        var obj     = e.target.__object__;
+      
+        // This is the new method which simplifies getting coordinates
+        var point = obj.getPoint(e);
+      
+      
+        if (point) {
+            
+            canvas.style.cursor = 'pointer';
+            
+            // Is this the same tooltip as the one (if any) that's already being shown
+            if (RGraph.Registry.Get('chart.tooltip') && RGraph.Registry.Get('chart.tooltip').__index__ == point[3]) {
+                return;
+            }
+
+            // Start afresh
+            RGraph.Redraw();
+
+            // Show the tooltip
+            RGraph.Tooltip(canvas, obj.Get('chart.labels')[point[3]], e.pageX, e.pageY, point[3]);
+
+            // Highlight the point
+            context.strokeStyle = 'gray';
+            context.fillStyle = 'white';
+            context.beginPath();
+            context.moveTo(point[1], point[2]);
+            context.arc(point[1], point[2], 2, 0, 6.26, 0);
+            context.stroke();
+            context.fill();
+            
+            return;
+        }
+        
+        canvas.style.cursor = 'default';
+    }
+    
+    window.onclick = function ()
+    {
+        RGraph.Redraw();
+    }
+</script>
+
+ + +

Combining the Line and Bar charts

+ +

+ You can combine the Bar and Line charts with a bit of magic. It's actually quite easy to do. Find out more here. + In the same vein, you can have Y axes on both the left and right. +

+ + + +

Alternative colors

+ +

+ Instead of a string stipulating the color, each element of the colors array can itself be a two element array, + stipulating the up color, and the down color. To use alternating colors you must also stipulate the alternate property: +

+ + + 
+myLine.Set('chart.colors.alternate', true);
+myLine.Set('chart.colors', ['red', ['blue', 'yellow'], 'green]);
+
+ + +

Accumulative filled Line charts

+ +

+ The default behaviour of filled Line charts is to "stack" the lines on top of each other. This allows them all + to be totally visible, no matter what (unless a line has a zero value of course). If this is not desired, then there is an + option (chart.filled.accumulative - true/false) to change this behaviour so the lines are plotted "as-is". + Keep in mind that if you set this option to false (ie the Lines are plotted as-is) it may be wiser to use + semi-transparent colors or some parts of data sets (or even entire data sets) may be hidden by others. There's a + comparison of the different modes here. +

+ + +

Custom tickmarks

+

+ If none of the available tickmark styles are suitable, you can instead specify a function object that draws the tickmark, + enabling you to draw the tickmark yourself. For example: +

+ + 
+<script>
+    line.Set('chart.tickmarks', myTick);
+
+    /**
+    * The function that is called once per tickmark, to draw it
+    * 
+    * @param object obj   The chart object
+    * @param array  data  The entire line data
+    * @param number value The individual points value
+    * @param number index The current index, in the data array
+    * @param number x     The X coordinate
+    * @param number y     The Y coordinate
+    * @param string color The color of the line
+    * @param number prevX The previous X coordinate
+    * @param number prevY The previous Y coordinate
+    */
+    function myTick (obj, data, value, index, x, y, color, prevX, prevY)
+    {
+        // Draw your custom tick here
+    }
+</script>
+
+ + +

The coords2 array

+ + An alternative method of indexing the chart coordinates is available in obj.coords2. With this array, all of the first + lines coordinates are available in obj.coords2[0], the second lines coordinates in obj.coords2[1] and so on. + + \ No newline at end of file diff --git a/schall/static/RGraph/docs/line_filled.html b/schall/static/RGraph/docs/line_filled.html new file mode 100644 index 0000000..dbc341b --- /dev/null +++ b/schall/static/RGraph/docs/line_filled.html @@ -0,0 +1,142 @@ + + + + + + RGraph: HTML5 Javascript charts library - The Line chart setting chart.filled.accumulative + + + + + + + + + + + + + + + + + + + + + + + + + + + +

RGraph: HTML5 Javascript charts library - The Line chart setting: chart.filled.accumulative

+ + + +

+ This page shows how the setting chart.filled.accumulative affects your charts. The chart on the left has + it enabled (the default), so the lines in effect sit on top of each other. The chart on the right has the setting + set to false so the points are drawn "as-is", ie not accumulatively. The first chart could be more useful if you wish + to see accumulated values, whereas the chart on the right might be better if you want to see individual values. +

+ +

+ Keep in mind that if you choose to use a non-accumulative chart the colors may be better as semi-transparent ones, + otherwise parts or all of some lines may get hidden by others. +

RGraph: HTML5 Javascript charts library - Meter charts documentation

+ + + +

+ These are Meter charts. Similar to half the Odometer. The difference is purely visual, but may well be more suited to + a control panel type application. +

+ +

+ The example file is here. +

+ + 
+<script>
+    window.onload = function ()
+    {
+        var meter = new RGraph.Meter('myCanvas', 50, 100, 60);
+        meter.Set('chart.contextmenu', [
+                                        ['Show palette', RGraph.Showpalette],
+                                        ['Clear annotations', function () {RGraph.Clear(meter.canvas); meter.Draw();}],
+                                        null,
+                                        ['Cancel', function () {}]
+                                       ]);
+        meter.Set('chart.annotatable', true);
+        meter.Set('chart.label.position', 'inside');

+

Canvas fallback content and visually impaired users

+ +

+ When using the canvas element you should be aware of the accessibility of your charts, for example where vision limited users are + concerned. Screen readers, for example, may not be able to convert a chart into something that is reasonable, so you should + consider + doing this yourself, possibly using the canvas fallback content (ie the content in between the canvas tags). A possible example + would be to put a table of data inside the canvas tag that the chart on the canvas represents. Doing this goes a long way + towards making the data available to everyone. You might also wish to consider using the full canvas + zoom or the resizing feature to enable people to enlarge the chart. +

+ + +
 
 
+

Upper and lower limits for horizontal bars

+ +

+ If you don't wish to specify an upper or lower limit for horizontal bars, and you just want them to extend to the upper or lower + limits of the chart, whatever they may be, you can specify null for the value determining how far they extend. For cases where + the X axis is in the middle and you're specifying a negative start value, or you want the bar to extend all the way to the + bottom, you can simply specify an arbitrary length (eg -999999). Eg: +

+ + 
myBar.Set('chart.background.hbars', [[0, null, 'green'], [0,-999999,'red']]);
+ + +
 
 
+

Setting the canvas width and height

+ +

+ To set the canvas width and height you must use the HTML width/height attributes and NOT CSS. If you do use CSS, the canvas + will be scaled, and not enlarged, to fit the new width/height. Eg: +

+ + 
<canvas id="myCanvas" width="200" height="100">[No canvas support]<canvas>
+ +

+ Note: + When you resize the canvas using CSS, not only will it be scaled (not enlarged), but it will also NOT be cleared. You can + see this effect on the animation page with the jQuery animation example. +

+ + +
 
 
+

The canvas coordinate system

+

+ The canvas coordinate system starts in the top left of the canvas (at [0,0] - the X value increasing as you go right + and the Y value as you go down), much like the CSS coordinates for the entire page. The + gutter goes around the canvas (ie top/bottom/left/right - where the labels and titles are placed), and the actual chart + sits in the middle. +

+ + +
 
 
+

RGraph and older browsers

+ +

+ Older versions of browsers are supported (assuming they have canvas support), however, if they don't support the canvas text + or shadow APIs these will naturally be unavailable. The charts will still be drawn, though without shadows or text. +

+ + +
 
 
+

RGraph and Microsoft Internet Explorer

+ +

+ You can now use RGraph with Internet Explorer 8 in conjunction with ExCanvas, (which brings a degree of <canvas> support to MSIE). + Bear in mind though that shadows are not available and thus are simulated. Microsoft Internet Explorer 9 has native <canvas> + support. +

+ + +
 
 
+ +

Debugging tips

+ +

+ If you're having a hard time debugging your chart, try these: +

+ +
    +
  • Ensure you have only one chart on the page
    • +
  • Make sure you have disabled your web browsers cache (the Firefox Web Developer toolbar can do this for Firefox)
    • +
  • + Try using Firebug for Firefox or the + Webkit developer tools for Google Chrome (CTRL_SHIFT+J) and Safari (CTRL+ALT+C). There's a + video about using the Chrome developer tools + here. These are very useful + tools that make development much easier. +
    • +
  • Reduce the page to the bare minimum.
    • +
  • Start with a very basic chart and build it up slowly.
    • +
+ + + + +
 
 
+

Inspecting an RGraph chart

+ +

+ To help when debugging your RGraph charts and canvas elements, you can use you browsers built in debugging tools. + An example is the WebKit developer tools which are available in Google Chrome and Apple Safari. There is a screenshot + of these tools (in docked mode) here. To view these + tools in Google Chrome press CTRL+SHIFT+J. Inspect the canvas, and then the associated object can be found via + the __object__ property. +

+ + + +
 
 
+

Double click context menus

+ +

+ Windows Opera, Windows Safari, Mac Safari and Mac Firefox all attach the context menu to the double click event (left mouse button), + not the right, in order to make it more reliable. +

+ + + +
 
 
+

Adding your own event handlers

+ +

+ Because each RGraph object exposes the canvas element (the same as what you get from document.getElementById()), + you can use normal procedures to add your own event handlers. Eg If you wanted to add your own onclick handler you could + do this: +

+ + 
+<script>
+    var myBar = new RGraph.Bar('cvs', [7,4,2,6,3,4,8]);
+    myBar.Draw();
+
+    myBar.canvas.onclick = function ()
+    {
+    }
+</script>
+
+

+ But what if, for example, you're using an RGraph feature which + uses the event handler that you need? In this case you can use the standard DOM2 method addEventListener(). This will add + your new event handler without replacing any existing one (ie the one installed by RGraph). For example: +

+ + 
+<script>
+    var myBar = new RGraph.Bar('cvs', [7,4,2,6,3,4,8]);
+    myBar.Draw();
+
+    function myFunc ()
+    {
+    }
+
+    myBar.canvas.addEventListener('click', myFunc, false)
+</script>
+
+ + + +
 
 
+

Carriage returns and newlines in labels

+ +

+ You can put carriage returns in your labels by using the string \r\n. This means your labels will span multiple lines. + Like so: +

+ + 
myBar.Set('chart.labels', 'John\r\n(Winner!)', ...)
+ + + +
 
 
+

Character set issues

+ +

+ If you're seeing strange, unrecognised characters in your text labels or titles, you may need to specify the correct + character set that the browser should use. In PHP you can do this with the header() function (which, as the + name suggests, sends a HTTP header): +

+ + 
<?php
+    header("Content-Type: text/html; charset=ISO-8859-1");
+?>
+ +

+ If you use Apache, you could use the header directive, though this may be overridden by other directives, + eg AddDefaultCharset. +

+ + +
 
 
+

How to identify an RGraph object

+ +

+ Because identity can sometimes be a tricky affair, there are a few RGraph properties that you can use to check whether an object + is an RGraph object: +

+ +
    +
  • obj.isRGraph - This is a boolean that you can use to clearly identify an RGraph object.
    • +
  • obj.type - This identifies the type of an RGraph object. It is a string which contains a one word description of the objects chart type, eg bar/line/pie.
    • +
+ + + + + + + + + + +
 
 
+

Static Y axis

+ + +
+ + +
+ +
+
+ + + + A static Y axis is useful if you have a wide chart but limited space. Whilst not part of the RGraph libraries itself, it can be + achieved with a little HTML, like the chart shown. The HTML and the script to achieve this is shown below. + It involves placing an extra canvas above the chart with the Y axis drawn on it. This canvas doesn't + move when the main canvas scrolls left and right. + +

+ + Note: Because Firefox doesn't support the event.offsetX and event.offsetY properties and they have to be simulated, + scrolling in conjunction with tooltips in this case and this browser doesn't work. + + 

+<div style="position: relative; float: right; margin-right: 10px; margin-top: 10px">
+    <!-- The width here is set further down the page in script -->
+    <canvas id="axes" width="0" height="200" style="position: absolute; top: 0; left: 0; z-index: 100"></canvas>
+    <div style="width: 600px; overflow: auto">
+        <canvas id="cvs" width="1000" height="200"></canvas>
+    </div>
+</div>
+
+<script>
+    window.onload = function ()
+    {
+        /**
+        * This is the script that draws the chart
+        */
+        line = new RGraph.Line('cvs', [3,15,22,26,28,24,22,25,23,24,26,23,24,25,27,28,29,26,23,22,24,21,24,25]);

Reducing white space

+ + + + + +

+ New in June 2011 is the ability to set the gutters independently. This removes the necessity to translate + and adjust the coordinates to get more space and is far more straight-forward. The new properties are: + +

    +
  • chart.gutter.left
    • +
  • chart.gutter.right
    • +
  • chart.gutter.top
    • +
  • chart.gutter.bottom
    • +
+ + You can read more about this change here. +

+ + +
+ + + +
 
 
+

In-graph labels

+ +

+ As well as an array of strings, like this: +

+ + 
obj.Set('chart.labels.ingraph', ['First label','Second label']);
+ +

+ The string can also be an array, consisting of color and placement information, like this: +

+ + 
obj.Set('chart.labels.ingraph', ['First label',['Second label', 'red', 'yellow', -1, 50] ]);
+ + +

+ You can read more information about this here. +

+ + +
 
 
+

Shorthand for in-graph labels

+

+ Instead of providing a full array of null elements for in-graph labels which may get a little unwieldy, + you can instead specify an integer that specifies how many elements to skip. Like this: +

+ + 
line.Set('chart.labels.ingraph', [6, 'July', 3, 'November']);
+ +
+
+ + +
 
 
+

DOM2 Event handlers

+

+ All the charts have now (1st October 2010) been converted to DOM2 for tooltips event registration. This allows them to + be far more co-operative if you're using events. Tooltips will not be compatible with MSIE8 - the charts will still be + drawn, albeit without tooltips. +

+ + + +
+ + + + + +
 
 
+

Data types

+

+ If your data values aren't the correct type - ie numbers - it can cause problems. Pay particular attention to this + when you're getting your data from data sources which may be classed as strings, such as JSON or AJAX requests. +

+ + + + + +
 
 
+

Creating your own chart type

+

+ If you wish to create your own chart type, there is a skeleton file + here that you can use as a starting point. + This file contains the bare bones of an RGraph object, such as the .Get() and .Set() methods, as well as examples + of common properties. +

+ + + +
 
 
+

World map

+

+ There is no function in RGraph to do mapping, either of the World or a smaller region. If this is what you want then you + may be interested in this HTML5 canvas based mapping system: + http://joncom.be/code/excanvas-world-map/ +

+ + + +
 
 
+

Adding text to your charts

+

+ You can add arbitrary text to your charts by using the RGraph API. For example you could use this code after the call to .Draw(): +

+ + 
+function DrawSubTitle (obj)
+{
+    var context = obj.context;
+    
+    context.beginPath();
+        context.fillStyle = 'gray';
+        RGraph.Text(context,
+                    'Verdana',
+                    7,
+                    obj.canvas.width / 2,
+                    obj.Get('chart.gutter.top') - 6,
+                    'The subtitle',
+                    'center',
+                    'center');
+    context.fill();
+}
+
+DrawSubTitle(myLine);
+
+ + +
 
 
+

Crosshairs

+ +
+ [No canvas support] + +
+ + + +

+ Some charts type have the ability to use crosshairs. The supported charts are: +

+ +
    +
  • Bar charts
    • +
  • Line charts
    • +
  • Scatter charts
    • +
  • Waterfall charts
    • +
+ +

+ There are various options that control the crosshairs, though because some apply to the readout, they are only applicable to + the Scatter chart. The crosshairs can be customised by stipulating the linewidth, the color and whether only the horizontal, + vertical or both lines are shown. +

+ +

Crosshairs and the Scatter chart

+

+ Because the X axis is scaled, the Scatter chart has the extra ability of having a coordinates readout when + the crosshairs are in use. This is shown in the example above. The appropriate properties are: +

+ +
    +
  • obj.canvas.__crosshairs_x__
    • +
  • obj.canvas.__crosshairs_y__
    • +
  • obj.canvas.__crosshairs_labels__ (this is the coordinates readout)
    • +
+ +

+ In the above example the coordinates are put in the text input by using the custom event oncrosshairs. This is as + follows: +

+ + 
+function myFunc (obj)
+{
+    var x = obj.canvas.__crosshairs_x__;
+    var y = obj.canvas.__crosshairs_y__;
+
+    document.getElementById("crosshairs.out").value = x + ',' + y;
+}
+RGraph.AddCustomEventListener(scatter, 'oncrosshairs', myFunc);
+
+ + +

RGraph: HTML5 Javascript charts library - Microsoft Internet Explorer (MSIE) support

+ + + +

+ +

+ Microsoft Internet Explorer 9 + +

+ Starting from preview 3, Internet Explorer 9 has support for canvas, including the text and shadow APIs. It also + benefits from hardware acceleration, and quick rendering times. +

+
+ +
+ + [No canvas support] + + + + + + +

Introduction

+ +

+ As of December 2009 RGraph now works partially with Internet Explorer without Google Chrome Frame. + Charts are rendered as VML. You are still recommended to use + Google Chrome Frame to get the best results. + The interactive features are unlikely to work correctly. RGraph only works with Microsoft + Internet Explorer 8. +

+ +

+ Thanks go to everyone involved with the ExCanvas project for providing the ExCanvas library. +

+ + +

Getting hold of ExCanvas

+ +

+ Google ExCanvas is distributed with RGraph in the "excanvas" directory. There is a minified gzip compressed version, along + with the original. +

+ + +

Caveats

+ +
    +
  • The interactive features of RGraph are unlikely to work correctly with MSIE 8.
    • +
  • Shadows are now available (on some chart types), albeit without blurring.
    • +
  • You must reference the Javascript libraries in the documents <head>.
    • +
  • You must use the window.onload event to create your chart.
    • +
  • If your page is large, there may be a slight pause before the window.onload event fires and thus creates the chart.
    • +
  • Changing the font that text is shown in is not available.
    • +
+ + +

Google Chrome Frame

+

+ Instead of ExCanvas you can also use Google Chrome Frame. This basically turns Internet Explorer into Google Chrome, and fully + supports RGraph. Since it involves a plugin installation, this is a better option if you can fully influence the users PC. If you + can fully influence the users PC however, a better option might be to simply use one of the browsers with native + support. +

+ + +
+ + + +

Using a dynamically created canvas

+

+ If you're creating your canvas dynamically there is an extra step that you must perform to allow it to be recognised by + ExCanvas: +

+ + 
+var canvas = document.createElement('CANVAS');
+    canvas.id = 'cvs';
+    canvas.width = 600;
+    canvas.height = 250;
+    canvas.style.border = '1px dashed black';
+document.body.appendChild(canvas);
+
+G_vmlCanvasManager.initElement(canvas);

+    }
+</script>
+
+ + obj.Explode()

+

+ The Explode() method allows you to programmatically trigger the exploding (ie the highlighting of) a particular segment. + The Explode() method is used like so: +

+ + 
+<script>
+    myObj = new RGraph.Pie('cvs', [8,9,4,6]);
+    myObj.Draw();
+
+    myObj.Explode(index, size);
+</script>
+
+ +

+ The index argument is the zero-index segment to operate on (counting from the north axis). An the size is measured in pixels. +

+ + Important Note + +

+ This method was formerly a common object method, called RGraph.getSegment(e), but has now (6th March 2011) been + moved to be part of the Pie chart object. +

+ + + + + +

RGraph: HTML5 Javascript charts library - Retrieving a PNG of your chart

+ + + + + +
+ PNG + [No canvas support] +
+ + +

+ RGraph provides an easy way to get a PNG image of your chart. This allows you to + easily save the image locally to use in (for example) a document, spreadsheet or presentation. +

+ +

+ Originally, the function was designed to be used with a context menu, so it is located in the RGraph.common.context.js. + Now though, you do not have to use the function with a context menu, and can instead pass in the canvas as the optional argument. There's an + example of its usage on the first Radar example. +

+ +
+ +

Include the context menu code:

+ 
<script src="../libraries/RGraph.common.context.js" ></script>
+ +

Add the context menu:

+ 
+myGraph.Set('chart.contextmenu', [
+                                  ['Get PNG', RGraph.showPNG],
+                                  null,
+                                  ['Cancel', function () {}]
+                                 ]);
+ +

Using the function without a context menu

+ +

+ If you want to use the function with a piece of text (or an image) as the "link", optionally positioned over the canvas, you can pass + the canvas into the function as an argument, along with the event object. +

+ + 
+<!-- This CSS positions the link over the top right of the canvas -->
+<style>
+    span#png_link {
+        position: absolute;
+        left: 450px;
+        top: 30px;
+        border: 1px black solid;
+        padding: 1px;
+        background-color: #eee;
+        cursor: pointer;
+    }
+</style>
+
+<div style="position: relative">
+    <span id="png_link" onclick="RGraph.showPNG(myCanvas, event)">Get PNG</span>
+    <canvas id="cvs" width="600" height="250">[No canvas support]</canvas>
+</div>
+
+ +

Retrieving just the PNG URL

+

+ If you just want to get the PNG image URL - this can be done with the standard canvas function.toDataUrl(): +

+ + 
var myUrl = myCanvas.toDataURL();
+ +

+ This gives you a data: URL which represents the canvas. Like this. + Because the URLs are very long there are some things that you should be aware of: +

+ +
    +
  • Google Chrome shows the image, but doesn't show the URL in the address bar
    • +
  • MSIE9 can show the image using the context menu API (top) method, but not the stand-alone image.

RGraph: HTML5 Javascript charts library - Radar charts documentation

+ +
+ This chart used to be called the Tradar chart (T standing for "Traditional" - there used to be two Radar charts in RGraph), + however now (July 2011), it has been renamed to the "Radar" chart to make it easier for people to identify.

+ + + +

+ A Radar chart. +

RGraph: HTML5 Javascript charts library - Resizing your charts

+ + + + [No canvas support] + +

 

+ +

+ RGraph has the facility to allow you to resize your charts. This is new as of 10th April 2010. Because of the + numerous events it has to install code on, it is unlikely to work with other dynamic features. The context + menu does though, and now that tooltips use DOM2 events, so do they. It can be useful if you are, + for example, doing a presentation and need to enlarge the chart. +

+ +

+ All you need to do to enable it is set chart.resizable to true. There are certain caveats that you should be aware of though: +

+ +
+ +
    +
  • + Charts can only be enlarged down and to the right, so you will get better results if your chart is not placed at the + right of the page. +
    • + +
  • + The minimum you can resize your charts to is 50% of the original chart width/height. +
    • + +
  • + Note: Resizing can change the layout of your page (reflows). As such you will need to be careful when laying out your + page, and you may need to experiment with things like CSS float:, width, height etc so that the effect is either not apparent + or is minimal. +
    • + +
  • + If your canvas is nested within a table, resizing can result in very minor (1-2px) positioning changes. These + can be mitigated by turning off table borders, setting the cellspacing to 0 and also setting the cellpadding to 0. +

+
+ + + + +

Properties

+ +

+ You can use these properties to control how the Rose chart appears. You can set them by using the Set() method. Eg: +

+ +

+ myRose.Set('name', 'value'); +

+ + + + + +

+ + + chart.gutter.top
+ The top gutter of the chart, (the gutter is where the labels and title are).
+ Default: 25

+ + + chart.gutter.bottom
+ The bottom gutter of the chart, (the gutter is where the labels and title are).
+ Default: 25

+ + + chart.margin
+ This is the margin that is either side of each segment. This allows you to have a gap between each segment. It is the size + of the gap in degrees. It doesn't apply to non-equi-angular Rose charts - only regular and stacked charts. +

+ Instead of using rgba(), you can use color definitions such as red along with this setting to add + transparency.
+ Default: null

+ + + chart.colors.sequential
+ Because of the new (as of July 2011) support for grouped Rose charts, the way colors are used has changed. So to have them + used in a sequential fashion as before the change, you will need to set this option to true. + Default: false

Default: null

+ +chart.title.vpos
+ This allows you to completely override the vertical positioning of the title. It should be a number between 0 and 1, and is multiplied with the gutter and then used as the vertical position. It can be useful if you need to have a large gutter.

+ + + chart.variant
+ This option can be either stacked (the default) or non-equi-angular. Just because his option is set to + stacked does not automatically mean your chart is stacked. If you don't suppy the appropriate data you chart + may well appear as a regular Rose chart. Examples of appropriate data: + +

+ A regular Rose chart +

+ + 
+myRose = new RGraph.Rose('myCanvas', [8,5,4,8,6,7,2,3,5,8]);
+
+ +

+ A stacked Rose chart +

+ + 
+myRose = new RGraph.Rose('myCanvas', [[2,6],[2,4],[1,5],[4,3],[7,5],[8,3],[4,5],[3,4],[2,6],[4,5]]);
+
+ +

+ A non-equi-angular Rose chart +

+ + 
+myRose = new RGraph.Rose('myCanvas', [[45,23],[45,23],[5,26],[78,4],[49,12],[49,21],[40,18],[48,12],[43,23],[45,12]]);
+myRose.Set('chart.variant', 'non-equi-angular');
+
+ +

+ It is important to note that with a non-equi-angular each "value" is actually an array consisting of two values, + as shown. The first value represents the magnitude of the segment (ie how far the segment extends outwards), + and the second value represents the size of the segment. The second value is relative to all the other second + values - it is not the absolute angle used. The angle is calculated for you. +

+ + Default: stacked

+ + + +
 
+

Methods

+ + obj.getSegment()

+ + obj.getSegment() makes it easy to determine which segment of the Rose chart was clicked on. It provides: + +
    +
  • Originating X coordinate
    • +
  • Originating Y coordinate
    • +
  • The starting radius of the segment
    • +
  • The ending radius of the segment
    • +
  • The starting angle (in degrees)
    • +
  • The ending angle (in degrees)
    • +
  • The numerical index of the segment
    • +
+ + 
+<script>
+    RGraph.Register(myGraph);
+    
+    myGraph.canvas.onclick = function (e)
+    {
+        RGraph.FixEventObject(e);
+        RGraph.Redraw();
+
+        var canvas  = e.target;
+        var context = canvas.getContext('2d');
+        var obj     = canvas.__object__;
+        var segment = obj.getSegment(e);
+        
+        if (segment) {
+            context.fillStyle = 'rgba(255,255,255,0.5)';
+            context.beginPath();
+                
+                // Angles are provided in degrees, so convert them to radians
+                segment[4] /= 57.29;
+                segment[5] /= 57.29;
+            
+                context.moveTo(segment[0], segment[1]);
+                context.arc(segment[0], segment[1], segment[3], segment[4], segment[5], 0);
+                context.arc(segment[0], segment[1], segment[2], segment[5], segment[4], true);
+            context.stroke();
+            context.fill();
+            
+            e.stopPropagation();
+        }
+    }
+    
+    window.onclick = function (e)
+    {
+        RGraph.Redraw();
+    }
+</script>
+
+ + Important Note + +

+ This method was formerly a common object method, called RGraph.getSegment(e), but has now (6th March 2011) been + moved to be part of the Rose chart object. +

+ + +
 
+

Stacked Rose charts

+

+ Rose charts can now be stacked, much like stacked Bar charts. For an example see the Rose + chart example page. The data should be supplied in the same format as a stacked Bar chart: +

+ + 
+myRose = new RGraph.Rose('myCanvas', [[4,6,2],[8,4,7],[4,3,6],[1,5,6]]);
+
+ + +
 
+

Non-equi-angular Rose charts

+

+ Rose charts can be displayed in a non-equi-angular mode. For an example see the + Rose chart example page. Instead of a plain array of values (as with a regular + Rose chart), each data point should itself be a two element array consisting of the magnitude value and also a relative + circular size. This second value is not the actual degrees used - these are calculated. For example: +

+ + 
+<script>
+    myRose = new RGraph.Rose('myCanvas', [[47,6],[48,2],[40,4],[43,5],[45,6]]);
+    myRose.Set('chart.variant', 'non-equi-angular');
+    myRose.Draw();
+</script>
+
+ + +
 
+

Rose chart specific animations

+ + There is a Rose chart Grow() animation, which can be used with regular and stacked Rose charts (not non-equi-angular charts). You + can see an example of it on the effects page. + + + \ No newline at end of file diff --git a/schall/static/RGraph/docs/rscatter.html b/schall/static/RGraph/docs/rscatter.html new file mode 100644 index 0000000..cc33585 --- /dev/null +++ b/schall/static/RGraph/docs/rscatter.html @@ -0,0 +1,373 @@ + + + + + + RGraph: HTML5 Javascript charts library - Radial scatter charts documentation + + + + + + + + + + + + + + + + + + + + +

RGraph: HTML5 Javascript charts library - Scatter charts documentation

+ + + +

+ Scatter charts. Used to represent many data points over a period of time. For example, events occurring in a given year. +

+ +

+ The example file is here. +

+ + + + 
+<script>
+    window.onload = function ()
+    {
+        var data = [
+                    [67,78,null, 'The winner!'], [67,40,'red'], [58,12], [78,56], [365,90], [360,300], [320,150], [15,45],

+</script>
+
+ +

+ As you can see each mark on the Scatter chart is made by supplying an array of up to 4 elements: +

+ +
    +
  • The X value (required)
    • +
  • The Y value (required)
    • +
  • The color (optional)
    • +
  • The tooltip for this mark (optional)
    • +
+ +

+ If you wish to specify a tooltip, but not a color (ie use the default color instead), you can pass null instead of a color. +

+ + + +

Properties

+ +

+ You can use these properties to control how the Scatter apears. You can set them by using the Set() method. Eg: +

+ +

+ myScatter.Set('chart.xmax', 365); +

myScatter.Set('chart.background.hbars', [[75, 10, 'yellow'], [85, 15, 'red']]);
+ + This would give you two bars, one red and a lower yellow bar. The units correspond to your scale, and are the + starting point and the height.
+ Default: null

+ + chart.background.vbars

Methods

+ + obj.getPoint(e) + +

+ This method makes it easier to get hold of which point on the Scatter chart has been hovered over. It returns an array of: +

+ +
    +
  • The X coordinate of the point
    • +

    • +
  • The index of the appropriate data point in the set
    • +
  • The tooltip (if any) for that particular point
    • +
+ + (If the return value is null, then no point is being hovered over.) An example usage is: + + 
+<script src="RGraph.common.core.js"></script>
+<script src="RGraph.line.js"></script>
+
+<canvas id="cvs" width="600" height="250" style="border: 1px gray dashed">[No canvas support]</canvas>

+              'Datapoint: ' + point[3] + '\r\n' +
+              'Tooltip: ' + point[4] + '\r\n');
+        }
+    }
+</script>
+
+ + +

Box plots

+ +

+ Instead of a single Y value, you have the ability to specify an array of 5, 6, 7 or 8 values, which will be used to make a box plot. + The example page shows a box plot. These values are (in order): + +

    +
  • Lower whisker
    • +
  • Bottom of box
    • +
  • Middle value (which isn't necessarily in the center of the box - this depends on your data)
    • +
  • Top of box
    • +
  • Upper whisker
    • +
  • Upper color (optional)
    • +
  • Lower color (optional)
    • +
  • Width (optional)
    • +
+ + 
+<script>

+    scatter8.Set('chart.title', 'An example of a boxplot');
+    scatter8.Set('chart.labels', ['Q1', 'Q2', 'Q3', 'Q4']);
+    scatter8.Set('chart.xmax', 365);

+    scatter8.Set('chart.boxplot.width', 12); // The default width
+    scatter8.Draw();
+</script>

Capped ends

+

+ For better compatibility with stock charts, you can now specify that the horizontal lines at the ends of the box plot + are not shown with chart.boxplot.capped. +

+ Instead of a simple string which is used as the label, each entry of the chart.labels array can be a two element array + consisting of the label, and the X value that the label should be placed at. For example: +

+ + 
+scatter.Set('chart.labels', [
+                             ['Quarter 1', 0],
+                             ['Quarter 2', 90],
+                             ['Quarter 3', 181],
+                             ['Quarter 4', 273]
+                            ]);
+
+ + + + +

Custom tickmarks

+ +

+ If none of the available tickmark styles are suitable, you can instead specify a function object that draws the tickmark, + enabling you to draw the tickmark yourself. For example: +

+ + 
+<script>
+    line.Set('chart.tickmarks', myTick);
+
+    /**
+    * The function that is called once per tickmark, to draw it
+    * 
+    * @param object obj   The chart object
+    * @param object data  The chart data
+    * @param number x     The X coordinate
+    * @param number y     The Y coordinate
+    * @param number xVal  The X value
+    * @param number yVal  The Y value
+    * @param number xMax  The maximum X scale value
+    * @param number xMax  The maximum Y scale value
+    * @param string color The color of the tickmark
+    */
+    function myTick (obj, data, x, y, xVal, yVal, xMax, yMax, color)
+    {
+        // Draw your custom tick here
+    }
+</script>
+
+ + +

Note about colors and the key

+

+ If you're using a key you may need to set chart.line.colors to allow it to use the correct colors. For example: +

+ + 
myObj.Set('chart.line.colors', ['red','green','blue']);
+ + +

Note about the oncrosshairs event

+

+ With the Scatter chart you can use the oncrosshairs custom event to pull out the crosshair coordinates, like this: + The coordinates are only available if you have them displayed. +

+ + 
+function myFunc (obj)
+{
+    var xCoord = obj.canvas.__crosshairs_x__;
+    var yCoord = obj.canvas.__crosshairs_y__;
+}
+RGraph.AddCustomEventListener(myScatter, 'oncrosshairs', myFunc);

RGraph: HTML5 Javascript charts library - Tooltips

+ + + +
+ [No canvas support]
+ Tooltip effect: + +
+ + + + + + +

Introduction

+ +

+ Tooltips are a very effective and straight forward way to extend your charts and add more information to them, without overloading + the user. +

+ + +

What can they hold?

+ +

+ At the base level, tooltips are DIVs, so they can hold a multitude of HTML - images, videos etc. See below + for information on showing charts in tooltips. +

+ + +

How can I specify them?

+ +

+ You can specify them by including the tooltips code and then using the chart.tooltips property. For example: +

+ +
    +
  1. + Include the RGraph libraries. + 
    +<script src="RGraph.common.core.js"></script>
+<script src="RGraph.common.tooltips.js"></script>
+<script src="RGraph.line.js"></script>
+
    +
    2. + +
  2. + Define your chart and set the tooltips property. + 
    +<script>
+    window.onload = function ()
+    {
+        var line = new RGraph.Line('cvs', [64,34,26,35,51,24]);
+        line.Set('chart.tooltips', ['<b>Winner!</b><br />John', 'Fred', 'Jane', 'Lou', 'Pete', 'Kev']);
+        line.Set('chart.tooltips.effect', 'expand');
+        line.Set('chart.hmargin', 10);
+        line.Set('chart.linewidth', 2);
+        line.Set('chart.shadow', true);
+        line.Set('chart.shadow.offsetx', 0);
+        line.Set('chart.shadow.offsety', 0);
+        line.Set('chart.shadow.color', 'green');
+        line.Set('chart.shadow.blur', 25);
+        line.Set('chart.colors', ['green']);
+        line.Set('chart.tickmarks', 'circle');
+        line.Set('chart.labels', ['John', 'Fred', 'Jane', 'Lou', 'Pete', 'Kev']);
+        line.Draw();
+    }
+</script>
+
    +
    3. +
+ + +

What can I specify?

+ +

+ The tooltips that you specify are usually strings (which can contain HTML). They can however also be functions which are called when they're about + to be displayed. The function should return the text that is used as the tooltip. You have the option to either specify + one function per data point, or just one function for all of the tooltips. You can mix functions and strings if you wish. + These functions are passed the numerical, zero-indexed tooltip index and the return value is used as the tooltip + text. So to summarise: +

+ +
    +
  • + An array of strings. The string is used as the tooltip. Eg: + 
    myGraph.Set('chart.tooltips', ['John', 'Fred', 'Lou']);
    +
    • + +
  • + An array of function objects. Each function is called and should return the text to be used. Eg: + 
    myGraph.Set('chart.tooltips', [getJohnTooltip, getFredTooltip, getLouTooltip]);
    +
    • + +
  • + A single function object. This is probably the most useful. This function is called whenever a tooltip + is about to be displayed, and passed the numerical, zero-indexed tooltip index of the point on the chart. + The function should return the text to be used as the tooltip. Note that the function you specify is called + before + the tooltip DIV has been created, so you cannot access it. If you wish to customise the appearance + of the tooltip, you can use either the tooltip CSS class or a call to setTimeout(). Eg: + 
    myGraph.Set('chart.tooltips', getTooltip);
    +
    • + +
  • + An array of DIV ids. This will make working with large tooltips easier. You basically specify the id of a DIV whose + .innerHTML is then used as the tooltip. Only the contents of the DIV are used, not the DIV itself, so you can hide + the DIV by setting its display CSS value to none. For example: + + 
    myBar.Set('chart.tooltips', ['id:myDiv', ...])
    +
    • +
+ + +

Can I show charts in tooltips?

+ + [No canvas support] + +

+ You can, and with the custom event support that RGraph has, it's reasonably easy. Simply attach your function that + creates the chart to the ontooltip event. This allows the tooltip HTML to be created and added to the page + so that the code that creates the chart can run. The sequence is: +

+ +
    +
  1. Specify the HTML for the tooltip as normal (including the <canvas> tag).
    2. +
  2. Use the ontooltip RGraph event so that a function is called when a tooltip is shown.
    3. +
  3. This function should subsequently create the chart.
    4. +
+ +

+ The tooltip DIV is to be found in the RGraph registry - RGraph.Registry.Get('chart.tooltip'). And if you want it the + numerical zero indexed count of the tooltip is to be found in the __index__ property: + RGraph.Registry.Get('chart.tooltip').__index__ +

+ + 
+<script src="RGraph.common.core.js" ></script>
+<script src="RGraph.common.tooltips.js" ></script>

+        bar.Set('chart.colors', ['blue']);
+        bar.Set('chart.ymax', 100);
+        bar.Set('chart.labels', labels);
+        bar.Draw();
+        
+        RGraph.AddCustomEventListener(line, 'ontooltip', CreateTooltipGraph);
+    }
+      
+
+    
+    /**
+    * This is the function that is called by the ontooltip event to create the tooltip charts
+    * 
+    * @param obj object   The chart object
+    */
+    function CreateTooltipGraph(obj)
+    {
+        // This data could be dynamic
+        var line  = new RGraph.Line('__tooltip_canvas__', [5,8,7,6,9,5,4,6,3,5,4,4]);
+        line.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+        line.Set('chart.hmargin', 5);
+        line.Set('chart.tickmarks', 'endcircle');
+        line.Set('chart.background.grid.autofit', true);
+        line.Draw();
+    }
+    
+</script>
+
+ +

+ If you want to see more source code, simply view the source of this page and look at the code that creates the bar chart. + There's also a basic stripped-down example here. +

+ +
+ + +

Can I customise the appearance of tooltips?

+ +

+ Yes. You can either use the default CSS class RGraph_tooltip, or you can specify a specific CSS class that a + charts tooltips should use with the property chart.tooltips.css.class. The two charts on this page have + different looking tooltips by using this method - the line chart uses the default look, whilst the bar chart + overrides the CSS class name and sets it to bar_chart_tooltips_css. For example: +

+ + 
bar.Set('chart.tooltips.css.class', 'bar_chart_tooltips_css');
+ + 
+<style>
+    .bar_chart_tooltips_css {
+        background-color: white ! important;
+        border: 2px solid black ! important;
+        padding: 3px;
+    }
+</style>
+
+ +

+ You can read more about RGraph CSS classes here. +

+ + +

What tooltip effects are available?

+ +

+ These effects are available to you: +

+ +
    +
  • fade
    • +
  • expand
    • +
  • contract
    • +
  • snap
    • +
  • none
    • +
+ +

+ All of them are as their names imply. fade is a straight forward fade in effect, expand is another effect + which expands outward from the center of the tooltip, contract is like the expand effect but in reverse, snap is an effect which can be used in a limited set of circumstances + and "snaps" to the current mouse position and none is simply no effect at all. The default effect used + by all chart types is fade. Note: If you're showing canvases in your tooltips then the expand, contract and snap + effects will not work - you must use fade or none. +

+ +

+ Note: The snap effect is only available to chart types where the tooltip is triggered using the onmousemove event. + Currently this means the Line chart, Rscatter chart, Scatter chart and Radar chart. It can also + be negatively effected when using multiple charts on one page. +

+ + + +

Tooltips, the clipboard and Firefox

+ +

+ If you're using Firefox, there's a note about tooltips and the clipboard (ie copying text) on the issues page. +

+ + +

Can I override the tooltip function?

+ +

+ You can by stipulating chart.tooltips.override. This should be a function object that handles everything with regard + to showing the tooltip. Highlighting the chart is still done for you - the override function is only concerned with showing + the tooltip. The override function is passed these arguments: +

+ +
    +
  • canvas - The HTML canvas element, the same as what you get from document.getElementById()
    • +
  • text - The tooltip text (id:xxx strings are NOT expanded)
    • +
  • x - The X coordinate in relation to the entire page
    • +
  • y - The Y coordinate in relation to the entire page
    • +
  • index - The numerical index of the tooltip in the original tooltip array
    • +
+ +

+ Note: Although "id:xxx" strings are not expanded for you, you can easily do this yourself by using the + RGraph.getTooltipText('id:xxx') function. +

+ + 
+<script>
+    function tooltip_override (canvas, text, x, y, idx)
+    {
+        alert('In tooltip override function...');
+    }
+    myObj.Set('chart.tooltips.override', tooltip_override);
+</script>

RGraph: HTML5 Javascript charts library - What is HTML5 canvas?

+ + + + + + +

Introduction

+ +

+ HTML5 canvas is a new HTML tag (<canvas>) which is part of the forthcoming HTML5 standard. It allows bitmap + drawing which is controlled using Javascript, and is what the RGraph libraries use to draw the charts. You could + liken it to a piece of paper which is part of your HTML page, on to which you can draw. Because you use Javascript to + draw on the canvas it becomes part of your page and allows interaction very easily. +

+ +

+ Canvas uses a "fire and forget" drawing methodology - there is no DOM that is maintained, so if you want to alter something + you will probably have to redraw the entire canvas. The lack of a DOM means that canvas is fast to draw on and very + responsive - important when you're providing iteractive charts to your users. +

+ + +

History

+

+ HTML5 canvas was originally introduced by Apple for use in WebKit (which is used in their Safari browser and Google Chrome). + It is now part of the HTML5 specification and supported by the majority (if not all) of modern web browsers. +

+ + +

Example

+ + [No canvas support] + + +

+ The example to the right is a very simple case of drawing a few primitives on the canvas. The dotted border is + provided by CSS to illustrate the drawing area. +

+ +

+ The <canvas> tag itself is defined with just a width/height/id attribute. The one here also has a style attribute + to make it more evident in the page. The HTML used is shown below: +

+ +
+ + 
+<canvas id="cvs" width="375" height="250">[No canvas support]<canvas>
+
+ + The content in between the tags is not shown if the browser supports canvas, and is if the browser doesn't. This provides + for fallback content if the users browser doesn't support canvas. + + +

HTML5 Canvas compared to SVG

+

+ HTML5 canvas can be compared (a bit) to SVG - which is a vector based alternative for drawing in HTML pages. SVG is + at a more abstract level than canvas and maintains a record of everything drawn, using a DOM. This is then converted + to a bitmap when shown. In the above example, if the blue squares coordinates are changed (eg in an animation), + then the whole canvas needs to be cleared and redrawn for each frame. +

+ +

+ As a result of not having to maintain a DOM <canvas> is fast to draw on and display to the browser. +

+ + +

Browser support for HTML5 canvas

+

+ The majority of current browsers support canvas, including IE9. Earlier versions of MSIE have some support through + compatibility layers provided by Google and Mozilla. One such library - ExCanvas - is provided in the RGraph archive + allowing IE8 to display the graphs, albeit without many of the dynamic features. You can read more on this + here. +

+ + + + + + + + +

Canvas mode

+ + + + + + + + + + + +
+

+ As of November 2009 RGraph has had the ability to provide a zoom facility. It's designed to be used in + conjunction with a context menu as in the example to the right. +

+ +

+ You can control the zoom using these properties: +

+ +
    +
  • chart.zoom.modeDefault: canvas
    • +
  • chart.zoom.factorDefault: 1.5
    • +
  • chart.zoom.fade.in Default: true
    • +
  • chart.zoom.fade.out Default: true
    • +
  • chart.zoom.hdir Default: right
    • +
  • chart.zoom.vdir Default: down
    • +
  • chart.zoom.delay Default: 50
    • +
  • chart.zoom.frames Default: 10
    • +
  • chart.zoom.shadow Default: true
    • +
  • chart.zoom.mode Default: canvas
    • +
  • chart.zoom.thumbnail.width Default: 75
    • +
  • chart.zoom.thumbnail.height Default: 75
    • +
  • chart.zoom.background Default: true
    • +
+ 		+ [No canvas support] +
+ The possible values of chart.zoom.hdir are: left, center, right. + The possible values of chart.zoom.vdir are: up, center, down. chart.zoom.delay + is the delay in between frames (in milliseconds) and chart.zoom.frames is the number of frames in the zoom. chart.zoom.shadow + is whether the zoomed canvas has a shadow or not. The possible values of chart.zoom.mode are canvas (default) + and thumbnail. +
+ + + +
+ + 
+<script>
+    var graph = new RGraph.Line('myc', [4,6,8,7,9,4,3,8,7,4,5,5,5]);

Thumbnail mode

+ + [No canvas support] + +

+ The zoom has an alternative thumbnail mode, which displays a small thumbnail zoom instead of zooming the entire canvas. + The chart to the left shows an example of this. +

+ +

+ It uses some of the same properties as the regular zoom, eg chart.fade.in, chart.fade.out, chart.zoom.shadow +

+ +
+ + 
+<script>
+    var myLine = new RGraph.Line('myc2', [40,48,45,64,34,22,23,56,56,54,84,44], [4,5,6,7,20,21,1,9,9,8,5,4]);
+    myLine.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);
+    myLine.Set('chart.hmargin', 10);
+    myLine.Set('chart.linewidth', 3);
+    myLine.Set('chart.title', 'A sample line chart');
+    myLine.Set('chart.zoom.mode', 'thumbnail');
+    myLine.Set('chart.zoom.vdir', 'center');
+    myLine.Set('chart.zoom.thumbnail.width', 100);
+    myLine.Set('chart.zoom.thumbnail.height', 100);
+    myLine.Set('chart.colors', ['red', 'black']);
+    myLine.Set('chart.shadow', true);
+    myLine.Set('chart.contextmenu', [['Zoom entire chart', RGraph.Zoom]]);
+</script>
+
+ +

+ Making the zoom circular

+ A circular zoom window + It is possible to make the zoom in area mode circular by utilising the border-radius CSS property. Currently support for + this is limited to FireFox 4b7+ and MSIE9, so it's not part of the main RGraph software. The CSS ncessary to achieve this is + thus: +

+ + 
+<style>
+    .RGraph_zoom_window {
+        border-radius: 50px ! important;
+    }
+</style>
+
+ + This a chart demonstrating this technique here. Note that browser support for this technique is limited. + +
+ + + +

Area mode

+ + [No canvas support] + +

+ Another type of zoom available is area. This is somewhat similar to thumbnail, but allows you to draw a rectangle around + the specific area that you want to zoom. +

+ +

+ Again, this uses some common zoom properties, such as chart.zoom.factor. +

+ +

+ Once visible, you can drag the zoomed area around with the left mouse button (a left drag), and drag the zoomed canvas around + within the zoom by using the right mouse button (a right-drag). And a double click will expand the zoomed area to cover the + whole canvas. +

+ +
+ + 
+<script>
+    var myLine = new RGraph.Line('myc3', [15,30,62,26,46,86,48,51,51,35,32, 35]);
+    myLine.Set('chart.zoom.mode', 'area');
+    myLine.Set('chart.hmargin', 10);
+    myLine.Set('chart.linewidth', 1);
+    myLine.Set('chart.title', 'A chart with zoom in area mode');
+    myLine.Set('chart.tickmarks', 'endcircle');
+    myLine.Set('chart.labels', ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']);

RGraph: HTML5 Javascript charts library - Bar charts

+ + + +
+

+ The bar chart is probably one of the most widely used of charts, and also one of the most versatile. It's defined as a chart with + rectangular bars with lengths proportional to the values they represent. The bar chart can be used to represent two + or more values. With grouped and stacked bar charts, you can visualise two or more sets of data. For example two years + worth of sales figures. Doing this you will be able to easily see differences, for example a better year when it comes + to sales. You can also show negative values by having the X axis in the center, like the examples shown. If you use a + grouped or stacked bar chart, a key may be helpful to your users. +

+ +

+ By using the tooltips feature, you can provide more detail about what a particular bar represents. The tooltips in + RGraph can contain wide range of HTML, so you can use them to show photos or movies for example. +

RGraph: Javascript charts & HTML5 canvas charts - A text function that does horizontal and vertical alignment (and spins)

+ + + + + + + + + + + +
The fallback HTML
+   +   + +
+ +

+ RGraph.Text() is a text drawing function that allows vertical and horizontal alignment, and allows you to specify the angle of the + text too. The animation is done by a simple gobal variable, setTimeout() and redrawing the entire + canvas every frame. Perhaps not the most efficient of methods, but remember that your Javascript will likely be + running on computers that have more processing power than + some small countries... Reset the page +

+ +

+ In a similar vein you could easily make some text that bounces from one side of the screen to the other, + hurrah - the return of <marquee>! +

+ +
+ More examples can be found on the individual example pages, and a more complete + reference to the Text() function can be found in the API docs. +

RGraph: HTML5 Javascript charts library - Vertical Progress bar

+ + + +

+ This is a Progress Bar for showing state. You can show anything with it - use it to show load on your server, + or percentage space free on your servers disk drive. You could even incorporate it with some AJAX to retrieve status information + from your webserver dynamically, making the Progress Bar realtime. To redraw the progress bar simply call RGraph.Clear() + (which clears the canvas) and then call myProgress.Draw() again. +

+ +

+ The colours, title and scale are configurable, allowing you to represent a wide range of values. +

+
+ + + + + + + + + + + + + + + [IE8+ is required to view the charts.] + +

Faster websites with RGraph

+

+ RGraph is a Javascript charts library. Using the new HTML5 canvas tag, RGraph charts are created in the web + browser, meaning quicker pages and less web server load. Using RGraph is an easy way of speeding up your website. + +

+

+ RGraph produces a wide variety of chart types - examples and documentation below. +

+ + +
+

+ + + +
