Read more at the +website: + + http://code.google.com/p/flot/ + +Take a look at the examples linked from above, they should give a good +impression of what Flot can do and the source code of the examples is +probably the fastest way to learn how to use Flot. + + +Installation +------------ + +Just include the Javascript file after you've included jQuery. + +Generally, all browsers that support the HTML5 canvas tag are +supported. + +For support for Internet Explorer < 9, you can use Excanvas, a canvas +emulator; this is used in the examples bundled with Flot. You just +include the excanvas script like this: + + <!--[if lte IE 8]><script language="javascript" type="text/javascript" src="excanvas.min.js"></script><![endif]--> + +If it's not working on your development IE 6.0, check that it has +support for VML which Excanvas is relying on. It appears that some +stripped down versions used for test environments on virtual machines +lack the VML support. + +You can also try using Flashcanvas (see +http://code.google.com/p/flashcanvas/), which uses Flash to do the +emulation. Although Flash can be a bit slower to load than VML, if +you've got a lot of points, the Flash version can be much faster +overall. Flot contains some wrapper code for activating Excanvas which +Flashcanvas is compatible with. + +You need at least jQuery 1.2.6, but try at least 1.3.2 for interactive +charts because of performance improvements in event handling. + + +Basic usage +----------- + +Create a placeholder div to put the graph in: + + <div id="placeholder"></div> + +You need to set the width and height of this div, otherwise the plot +library doesn't know how to scale the graph. You can do it inline like +this: + + <div id="placeholder" style="width:600px;height:300px"></div> + +You can also do it with an external stylesheet. Make sure that the +placeholder isn't within something with a display:none CSS property - +in that case, Flot has trouble measuring label dimensions which +results in garbled looks and might have trouble measuring the +placeholder dimensions which is fatal (it'll throw an exception). + +Then when the div is ready in the DOM, which is usually on document +ready, run the plot function: + + $.plot($("#placeholder"), data, options); + +Here, data is an array of data series and options is an object with +settings if you want to customize the plot. Take a look at the +examples for some ideas of what to put in or look at the reference +in the file "API.txt". Here's a quick example that'll draw a line from +(0, 0) to (1, 1): + + $.plot($("#placeholder"), [ [[0, 0], [1, 1]] ], { yaxis: { max: 1 } }); + +The plot function immediately draws the chart and then returns a plot +object with a couple of methods. + + +What's with the name? +--------------------- + +First: it's pronounced with a short o, like "plot". Not like "flawed". + +So "Flot" rhymes with "plot". + +And if you look up "flot" in a Danish-to-English dictionary, some up +the words that come up are "good-looking", "attractive", "stylish", +"smart", "impressive", "extravagant". One of the main goals with Flot +is pretty looks. |
