-Flot 0.7
---------
-
-API changes:
-
-Multiple axes support. Code using dual axes should be changed from
-using x2axis/y2axis in the options to using an array (although
-backwards-compatibility hooks are in place). For instance,
-
-  {
-    xaxis: { ... }, x2axis: { ... },
-    yaxis: { ... }, y2axis: { ... }
-  }
-
-becomes
-
-  {
-    xaxes: [ { ... }, { ... } ],
-    yaxes: [ { ... }, { ... } ]
-  }
-
-Note that if you're just using one axis, continue to use the
-xaxis/yaxis directly (it now sets the default settings for the
-arrays). Plugins touching the axes must be ported to take the extra
-axes into account, check the source to see some examples.
-
-A related change is that the visibility of axes is now auto-detected.
-So if you were relying on an axis to show up even without any data in
-the chart, you now need to set the axis "show" option explicitly.
-
-"tickColor" on the grid options is now deprecated in favour of a
-corresponding option on the axes, so { grid: { tickColor: "#000" }}
-becomes { xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} },
-but if you just configure a base color Flot will now autogenerate a
-tick color by adding transparency. Backwards-compatibility hooks are
-in place.
-
-Final note: now that IE 9 is coming out with canvas support, you may
-want to adapt the excanvas include to skip loading it in IE 9 (the
-examples have been adapted thanks to Ryley Breiddal). An alternative
-to excanvas using Flash has also surfaced, if your graphs are slow in
-IE, you may want to give it a spin:
-
-  http://code.google.com/p/flashcanvas/
-
-
-Changes:
-
-- Support for specifying a bottom for each point for line charts when
-  filling them, this means that an arbitrary bottom can be used
-  instead of just the x axis (based on patches patiently provided by
-  Roman V. Prikhodchenko).
-- New fillbetween plugin that can compute a bottom for a series from
-  another series, useful for filling areas between lines (see new
-  example percentiles.html for a use case).
-- More predictable handling of gaps for the stacking plugin, now all
-  undefined ranges are skipped.
-- Stacking plugin can stack horizontal bar charts.
-- Navigate plugin now redraws the plot while panning instead of only
-  after the fact (can be disabled by setting the pan.frameRate option
-  to null), raised by lastthemy (issue 235).
-- Date formatter now accepts %0m and %0d to get a zero-padded month or
-  day (issue raised by Maximillian Dornseif).
-- Revamped internals to support an unlimited number of axes, not just
-  dual (sponsored by Flight Data Services,
-  www.flightdataservices.com).
-- New setting on axes, "tickLength", to control the size of ticks or
-  turn them off without turning off the labels.
-- Axis labels are now put in container divs with classes, for instance
-  labels in the x axes can be reached via ".xAxis .tickLabel".
-- Support for setting the color of an axis (sponsored by Flight Data
-  Services, www.flightdataservices.com).
-- Tick color is now auto-generated as the base color with some
-  transparency (unless you override it).
-- Support for aligning ticks in the axes with "alignTicksWithAxis" to
-  ensure that they appear next to each other rather than in between,
-  at the expense of possibly awkward tick steps (sponsored by Flight
-  Data Services, www.flightdataservices.com).
-- Support for customizing the point type through a callback when
-  plotting points and new symbol plugin with some predefined point
-  types (sponsored by Utility Data Corporation).
-- Resize plugin for automatically redrawing when the placeholder
-  changes size, e.g. on window resizes (sponsored by Novus Partners).
-  A resize() method has been added to plot object facilitate this.
-- Support Infinity/-Infinity for plotting asymptotes by hacking it
-  into +/-Number.MAX_VALUE (reported by rabaea.mircea).
-- Support for restricting navigate plugin to not pan/zoom an axis (based
-  on patch by kkaefer).
-- Support for providing the drag cursor for the navigate plugin as an
-  option (based on patch by Kelly T. Moore).
-- Options for controlling whether an axis is shown or not (suggestion
-  by Timo Tuominen) and whether to reserve space for it even if it
-  isn't shown.
-- New attribute $.plot.version with the Flot version as a string.
-- The version comment is now included in the minified jquery.flot.min.js.
-- New options.grid.minBorderMargin for adjusting the minimum margin
-  provided around the border (based on patch by corani, issue 188).
-- Refactor replot behaviour so Flot tries to reuse the existing
-  canvas, adding shutdown() methods to the plot (based on patch by
-  Ryley Breiddal, issue 269). This prevents a memory leak in Chrome
-  and hopefully makes replotting faster for those who are using $.plot
-  instead of .setData()/.draw(). Also update jQuery to 1.5.1 to
-  prevent IE leaks fixed in jQuery.
-- New real-time line chart example.
-
-- New hooks: drawSeries, shutdown
-
-Bug fixes:
-
-- Fixed problem with findNearbyItem and bars on top of each other
-  (reported by ragingchikn, issue 242).
-- Fixed problem with ticks and the border (based on patch from
-  ultimatehustler69, issue 236).
-- Fixed problem with plugins adding options to the series objects.
-- Fixed a problem introduced in 0.6 with specifying a gradient with {
-  brightness: x, opacity: y }.
-- Don't use $.browser.msie, check for getContext on the created canvas
-  element instead and try to use excanvas if it's not found (fixes IE
-  9 compatibility).
-- highlight(s, index) was looking up the point in the original s.data
-  instead of in the computed datapoints array, which breaks with
-  plugins that modify the datapoints (such as the stacking plugin).
-  Issue 316 reported by curlypaul924.
-- More robust handling of axis from data passed in from getData()
-  (problem reported by Morgan).
-- Fixed problem with turning off bar outline (issue 253, fix by Jordi
-  Castells).
-- Check the selection passed into setSelection in the selection
-  plugin, to guard against errors when synchronizing plots (fix by Lau
-  Bech Lauritzen).
-- Fix bug in crosshair code with mouseout resetting the crosshair even
-  if it is locked (fix by Lau Bech Lauritzen and Banko Adam).
-- Fix bug with points plotting using line width from lines rather than
-  points.
-- Fix bug with passing non-array 0 data (for plugins that don't expect
-  arrays, patch by vpapp1).
-- Fix errors in JSON in examples so they work with jQuery 1.4.2
-  (fix reported by honestbleeps, issue 357).
-- Fix bug with tooltip in interacting.html, this makes the tooltip
-  much smoother (fix by bdkahn). Fix related bug inside highlighting
-  handler in Flot.
-- Use closure trick to make inline colorhelpers plugin respect
-  jQuery.noConflict(true), renaming the global jQuery object (reported
-  by Nick Stielau).
-- Listen for mouseleave events and fire a plothover event with empty
-  item when it occurs to drop highlights when the mouse leaves the
-  plot (reported by by outspirit).
-- Fix bug with using aboveData with a background (reported by
-  amitayd).
-- Fix possible excanvas leak (report and suggested fix by tom9729).
-- Fix bug with backwards compatibility for shadowSize = 0 (report and
-  suggested fix by aspinak).
-- Adapt examples to skip loading excanvas (fix by Ryley Breiddal).
-- Fix bug that prevent a simple f(x) = -x transform from working
-  correctly (fix by Mike, issue 263).
-- Fix bug in restoring cursor in navigate plugin (reported by Matteo
-  Gattanini, issue 395).
-- Fix bug in picking items when transform/inverseTransform is in use
-  (reported by Ofri Raviv, and patches and analysis by Jan and Tom
-  Paton, issue 334 and 467).
-- Fix problem with unaligned ticks and hover/click events caused by
-  padding on the placeholder by hardcoding the placeholder padding to
-  0 (reported by adityadineshsaxena, Matt Sommer, Daniel Atos and some
-  other people, issue 301).
-- Update colorhelpers plugin to avoid dying when trying to parse an
-  invalid string (reported by cadavor, issue 483).

-Flot 0.6
---------
-
-API changes:
-
-1. Selection support has been moved to a plugin. Thus if you're
-passing selection: { mode: something }, you MUST include the file
-jquery.flot.selection.js after jquery.flot.js. This reduces the size
-of base Flot and makes it easier to customize the selection as well as
-improving code clarity. The change is based on a patch from andershol.
-
-2. In the global options specified in the $.plot command,
-"lines", "points", "bars" and "shadowSize" have been moved to a
-sub-object called "series", i.e.
-
-  $.plot(placeholder, data, { lines: { show: true }})
-
-should be changed to
-
-  $.plot(placeholder, data, { series: { lines: { show: true }}})
-
-All future series-specific options will go into this sub-object to
-simplify plugin writing. Backward-compatibility code is in place, so
-old code should not break.
-
-3. "plothover" no longer provides the original data point, but instead
-a normalized one, since there may be no corresponding original point.
-
-4. Due to a bug in previous versions of jQuery, you now need at least
-jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some
-improvements in event handling speed.
-
-
-Changes:
-
-- Added support for disabling interactivity for specific data series
-  (request from Ronald Schouten and Steve Upton).
-
-- Flot now calls $() on the placeholder and optional legend container
-  passed in so you can specify DOM elements or CSS expressions to make
-  it easier to use Flot with libraries like Prototype or Mootools or
-  through raw JSON from Ajax responses.
-
-- A new "plotselecting" event is now emitted while the user is making
-  a selection.
-
-- The "plothover" event is now emitted immediately instead of at most
-  10 times per second, you'll have to put in a setTimeout yourself if
-  you're doing something really expensive on this event.
-
-- The built-in date formatter can now be accessed as
-  $.plot.formatDate(...) (suggestion by Matt Manela) and even
-  replaced.
-
-- Added "borderColor" option to the grid (patch from Amaury Chamayou
-  and patch from Mike R. Williamson).
-
-- Added support for gradient backgrounds for the grid, take a look at
-  the "setting options" example (based on patch from Amaury Chamayou,
-  issue 90).
-
-- Gradient bars (suggestion by stefpet).
-  
-- Added a "plotunselected" event which is triggered when the selection
-  is removed, see "selection" example (suggestion by Meda Ugo);
-
-- The option legend.margin can now specify horizontal and vertical
-  margins independently (suggestion by someone who's annoyed).
-
-- Data passed into Flot is now copied to a new canonical format to
-  enable further processing before it hits the drawing routines. As a
-  side-effect, this should make Flot more robust in the face of bad
-  data (and fixes issue 112).
-
-- Step-wise charting: line charts have a new option "steps" that when
-  set to true connects the points with horizontal/vertical steps
-  instead of diagonal lines.
-
-- The legend labelFormatter now passes the series in addition to just
-  the label (suggestion by Vincent Lemeltier).
-
-- Horizontal bars (based on patch by Jason LeBrun).
-
-- Support for partial bars by specifying a third coordinate, i.e. they
-  don't have to start from the axis. This can be used to make stacked
-  bars.
-
-- New option to disable the (grid.show).
-
-- Added pointOffset method for converting a point in data space to an
-  offset within the placeholder.
-  
-- Plugin system: register an init method in the $.flot.plugins array
-  to get started, see PLUGINS.txt for details on how to write plugins
-  (it's easy). There are also some extra methods to enable access to
-  internal state.
-
-- Hooks: you can register functions that are called while Flot is
-  crunching the data and doing the plot. This can be used to modify
-  Flot without changing the source, useful for writing plugins. Some
-  hooks are defined, more are likely to come.
-  
-- Threshold plugin: you can set a threshold and a color, and the data
-  points below that threshold will then get the color. Useful for
-  marking data below 0, for instance.
-
-- Stack plugin: you can specify a stack key for each series to have
-  them summed. This is useful for drawing additive/cumulative graphs
-  with bars and (currently unfilled) lines.
-
-- Crosshairs plugin: trace the mouse position on the axes, enable with
-  crosshair: { mode: "x"} (see the new tracking example for a use).
-
-- Image plugin: plot prerendered images.
-
-- Navigation plugin for panning and zooming a plot.
-
-- More configurable grid.
-
-- Axis transformation support, useful for non-linear plots, e.g. log
-  axes and compressed time axes (like omitting weekends).
-
-- Support for twelve-hour date formatting (patch by Forrest Aldridge).
-
-- The color parsing code in Flot has been cleaned up and split out so
-  it's now available as a separate jQuery plugin. It's included inline
-  in the Flot source to make dependency managing easier. This also
-  makes it really easy to use the color helpers in Flot plugins.
-
-Bug fixes:
-
-- Fixed two corner-case bugs when drawing filled curves (report and
-  analysis by Joshua Varner).
-- Fix auto-adjustment code when setting min to 0 for an axis where the
-  dataset is completely flat on that axis (report by chovy).
-- Fixed a bug with passing in data from getData to setData when the
-  secondary axes are used (issue 65, reported by nperelman).
-- Fixed so that it is possible to turn lines off when no other chart
-  type is shown (based on problem reported by Glenn Vanderburg), and
-  fixed so that setting lineWidth to 0 also hides the shadow (based on
-  problem reported by Sergio Nunes).
-- Updated mousemove position expression to the latest from jQuery (bug
-  reported by meyuchas).
-- Use CSS borders instead of background in legend (fix printing issue 25
-  and 45).
-- Explicitly convert axis min/max to numbers.
-- Fixed a bug with drawing marking lines with different colors
-  (reported by Khurram).
-- Fixed a bug with returning y2 values in the selection event (fix
-  by exists, issue 75).
-- Only set position relative on placeholder if it hasn't already a
-  position different from static (reported by kyberneticist, issue 95).
-- Don't round markings to prevent sub-pixel problems (reported by Dan
-  Lipsitt).
-- Make the grid border act similarly to a regular CSS border, i.e.
-  prevent it from overlapping the plot itself. This also fixes a
-  problem with anti-aliasing when the width is 1 pixel (reported by
-  Anthony Ettinger).
-- Imported version 3 of excanvas and fixed two issues with the newer
-  version. Hopefully, this will make Flot work with IE8 (nudge by
-  Fabien Menager, further analysis by Booink, issue 133).
-- Changed the shadow code for lines to hopefully look a bit better
-  with vertical lines.
-- Round tick positions to avoid possible problems with fractions
-  (suggestion by Fred, issue 130).
-- Made the heuristic for determining how many ticks to aim for a bit
-  smarter.
-- Fix for uneven axis margins (report and patch by Paul Kienzle) and
-  snapping to ticks (concurrent report and patch by lifthrasiir).
-- Fixed bug with slicing in findNearbyItems (patch by zollman).
-- Make heuristic for x axis label widths more dynamic (patch by
-  rickinhethuis).
-- Make sure points on top take precedence when finding nearby points
-  when hovering (reported by didroe, issue 224).

-Flot 0.5
---------
-
-Backwards API change summary: Timestamps are now in UTC. Also
-"selected" event -> becomes "plotselected" with new data, the
-parameters for setSelection are now different (but backwards
-compatibility hooks are in place), coloredAreas becomes markings with
-a new interface (but backwards compatibility hooks are in place).
-
-
-Interactivity: added a new "plothover" event and this and the
-"plotclick" event now returns the closest data item (based on patch by
-/david, patch by Mark Byers for bar support). See the revamped
-"interacting with the data" example for some hints on what you can do.
-
-Highlighting: you can now highlight points and datapoints are
-autohighlighted when you hover over them (if hovering is turned on).
-
-Support for dual axis has been added (based on patch by someone who's
-annoyed and /david). For each data series you can specify which axes
-it belongs to, and there are two more axes, x2axis and y2axis, to
-customize. This affects the "selected" event which has been renamed to
-"plotselected" and spews out { xaxis: { from: -10, to: 20 } ... },
-setSelection in which the parameters are on a new form (backwards
-compatible hooks are in place so old code shouldn't break) and
-markings (formerly coloredAreas).
-
-Timestamps in time mode are now displayed according to
-UTC instead of the time zone of the visitor. This affects the way the
-timestamps should be input; you'll probably have to offset the
-timestamps according to your local time zone. It also affects any
-custom date handling code (which basically now should use the
-equivalent UTC date mehods, e.g. .setUTCMonth() instead of
-.setMonth().
-
-Added support for specifying the size of tick labels (axis.labelWidth,
-axis.labelHeight). Useful for specifying a max label size to keep
-multiple plots aligned.
-
-Markings, previously coloredAreas, are now specified as ranges on the
-axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings
-you can now draw horizontal/vertical lines by setting from and to to
-the same coordinate (idea from line support patch by by Ryan Funduk).
-
-The "fill" option can now be a number that specifies the opacity of
-the fill.
-
-You can now specify a coordinate as null (like [2, null]) and Flot
-will take the other coordinate into account when scaling the axes
-(based on patch by joebno).
-
-New option for bars "align". Set it to "center" to center the bars on
-the value they represent.
-
-setSelection now takes a second parameter which you can use to prevent
-the method from firing the "plotselected" handler. 
-
-Using the "container" option in legend now overwrites the container
-element instead of just appending to it (fixes infinite legend bug,
-reported by several people, fix by Brad Dewey).
-
-Fixed a bug in calculating spacing around the plot (reported by
-timothytoe). Fixed a bug in finding max values for all-negative data
-sets. Prevent the possibility of eternal looping in tick calculations.
-Fixed a bug when borderWidth is set to 0 (reported by
-Rob/sanchothefat). Fixed a bug with drawing bars extending below 0
-(reported by James Hewitt, patch by Ryan Funduk). Fixed a
-bug with line widths of bars (reported by MikeM). Fixed a bug with
-'nw' and 'sw' legend positions. Improved the handling of axis
-auto-scaling with bars. Fixed a bug with multi-line x-axis tick
-labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
-
-
-Flot 0.4
---------
-
-API changes: deprecated axis.noTicks in favor of just specifying the
-number as axis.ticks. So "xaxis: { noTicks: 10 }" becomes
-"xaxis: { ticks: 10 }"
-
-Time series support. Specify axis.mode: "time", put in Javascript
-timestamps as data, and Flot will automatically spit out sensible
-ticks. Take a look at the two new examples. The format can be
-customized with axis.timeformat and axis.monthNames, or if that fails
-with axis.tickFormatter.
-
-Support for colored background areas via grid.coloredAreas. Specify an
-array of { x1, y1, x2, y2 } objects or a function that returns these
-given { xmin, xmax, ymin, ymax }.
-
-More members on the plot object (report by Chris Davies and others).
-"getData" for inspecting the assigned settings on data series (e.g.
-color) and "setData", "setupGrid" and "draw" for updating the contents
-without a total replot.
-
-The default number of ticks to aim for is now dependent on the size of
-the plot in pixels. Support for customizing tick interval sizes
-directly with axis.minTickSize and axis.tickSize.
-
-Cleaned up the automatic axis scaling algorithm and fixed how it
-interacts with ticks. Also fixed a couple of tick-related corner case
-bugs (one reported by mainstreetmark, another reported by timothytoe).
-
-The option axis.tickFormatter now takes a function with two
-parameters, the second parameter is an optional object with
-information about the axis. It has min, max, tickDecimals, tickSize.
-
-Added support for segmented lines (based on patch from Michael
-MacDonald) and for ignoring null and bad values (suggestion from Nick
-Konidaris and joshwaihi). 
-
-Added support for changing the border width (joebno and safoo).
-Label colors can be changed via CSS by selecting the tickLabel class.
-
-Fixed a bug in handling single-item bar series (reported by Emil
-Filipov). Fixed erratic behaviour when interacting with the plot
-with IE 7 (reported by Lau Bech Lauritzen). Prevent IE/Safari text
-selection when selecting stuff on the canvas.
-
-
-
-Flot 0.3
---------
-
-This is mostly a quick-fix release because jquery.js wasn't included
-in the previous zip/tarball.
-
-Support clicking on the plot. Turn it on with grid: { clickable: true },
-then you get a "plotclick" event on the graph placeholder with the
-position in units of the plot.
-
-Fixed a bug in dealing with data where min = max, thanks to Michael
-Messinides.
-
-Include jquery.js in the zip/tarball.
-
-
-Flot 0.2
---------
-
-Added support for putting a background behind the default legend. The
-default is the partly transparent background color. Added
-backgroundColor and backgroundOpacity to the legend options to control
-this.
-
-The ticks options can now be a callback function that takes one
-parameter, an object with the attributes min and max. The function
-should return a ticks array.
-
-Added labelFormatter option in legend, useful for turning the legend
-labels into links.
-
-Fixed a couple of bugs.
-
-The API should now be fully documented.
-
-Patch from Guy Fraser to make parts of the code smaller.
-
-API changes: Moved labelMargin option to grid from x/yaxis.
-
-
-Flot 0.1
---------
-
-First public release.
