8### Bug fixes ###
9
10 - Added a work-around to disable the allocation of extra space for first and
11   last axis ticks, allowing plots to span the full width of their container.
12   A proper solution for this bug will be implemented in the 0.9 release.
13   (reported by Josh Pigford and andig, issue #1212, pull request #1290)
14
15 - Fixed a regression introduced in 0.8.1, where the last tick label would
16   sometimes wrap rather than extending the plot's offset to create space.
17   (reported by Elite Gamer, issue #1283)
18
19 - Fixed a regression introduced in 0.8.2, where the resize plugin would use
20   unexpectedly high amounts of CPU even when idle.
21   (reported by tommie, issue #1277, pull request #1289)
22
23 - Fixed the selection example to work with jQuery 1.9.x and later.
24   (reported by EGLadona and dmfalke, issue #1250, pull request #1285)

68
69### Bug fixes ###
70
71 - Fixed an unexpected change in behavior that resulted in duplicate tick
72   labels when using a plugin, like flot-tickrotor, that overrode tick labels.
73   (patch by Mark Cote, pull request #1091)
74
75 - Fixed a regression from 0.7 where axis labels were given the wrong width,
76   causing them to overlap at certain scales and ignore the labelWidth option.
77   (patch by Benjamin Gram, pull request #1177)
78
79 - Fixed a bug where the second axis in an xaxes/yaxes array incorrectly had
80   its 'innermost' property set to false or undefined, even if it was on the
81   other side of the plot from the first axis. This resulted in the axis bar
82   being visible when it shouldn't have been, which was especially obvious
83   when the grid had a left/right border width of zero.
84   (reported by Teq1, fix researched by ryleyb, issue #1056)
85
86 - Fixed an error when using a placeholder that has no font-size property.

88
89 - Fixed a regression from 0.7 where nulls at the end of a series were ignored
90   for purposes of determing the range of the x-axis.
91   (reported by Munsifali Rashid, issue #1095)
92
93 - If a font size is provided, base the default lineHeight on that size rather
94   that the font size of the plot placeholder, which may be very different.
95   (reported by Daniel Hoffmann Bernardes, issue #1131, pull request #1199)
96
97 - Fix broken highlighting for right-aligned bars.
98   (reported by BeWiBu and Mihai Stanciu, issues #975 and #1093, with further
99   assistance by Eric Byers, pull request #1120)
100
101 - Prevent white circles from sometimes showing up inside of pie charts.
102   (reported by Pierre Dubois and Jack Klink, issues #1128 and #1073)
103
104 - Label formatting no longer breaks when a page contains multiple pie charts.
105   (reported by Brend Wanders, issue #1055)
106
107 - When using multiple axes on opposite sides of the plot, the innermost axis
108   coming later in the list no longer has its bar drawn incorrectly.
109   (reported by ryleyb, issue #1056)
110
111 - When removing series labels and redrawing the plot, the legend now updates
112   correctly even when using an external container.
113   (patch by Luis Silva, issue #1159, pull request #1160)
114
115 - The pie plugin no longer ignores the value of the left offset option.
116   (reported by melanker, issue #1136)

119   sides of the plot where there was no last tick label.
120   (reported by sknob001, issue #1048, pull request #1200)
121
122 - Fixed incorrect tooltip behavior in the interacting example.

129   (patch by Anthony Ryan, pull request #1180)
130
131 - Worked around a browser issue that caused bars to appear un-filled.
132   (reported by irbian, issue #915)
133
134## Flot 0.8.1 ##
135
136### Bug fixes ###
137
138 - Fixed a regression in the time plugin, introduced in 0.8, that caused dates
139   to align to the minute rather than to the highest appropriate unit. This
140   caused many x-axes in 0.8 to have different ticks than they did in 0.7.
141   (reported by Tom Sheppard, patch by Daniel Shapiro, issue #1017, pull
142   request #1023)
143
144 - Fixed a regression in text rendering, introduced in 0.8, that caused axis
145   labels with the same text as another label on the same axis to disappear.
146   More generally, it's again possible to have the same text in two locations.
147   (issue #1032)
148
149 - Fixed a regression in text rendering, introduced in 0.8, where axis labels
150   were no longer assigned an explicit width, and their text could not wrap.
151   (reported by sabregreen, issue #1019)
152
153 - Fixed a regression in the pie plugin, introduced in 0.8, that prevented it
154   from accepting data in the format '[[x, y]]'.
155   (patch by Nicolas Morel, pull request #1024)
156
157 - The 'zero' series option and 'autoscale' format option are no longer
158   ignored when the series contains a null value.
159   (reported by Daniel Shapiro, issue #1033)
160
161 - Avoid triggering the time-mode plugin exception when there are zero series.
162   (reported by Daniel Rothig, patch by Mark Raymond, issue #1016)
163
164 - When a custom color palette has fewer colors than the default palette, Flot
165   no longer fills out the colors with the remainder of the default.
166   (patch by goorpy, issue #1031, pull request #1034)
167
168 - Fixed missing update for bar highlights after a zoom or other redraw.
169   (reported by Paolo Valleri, issue #1030)
170
171 - Fixed compatibility with jQuery versions earlier than 1.7.
172   (patch by Lee Willis, issue #1027, pull request #1027)
173
174 - The mouse wheel no longer scrolls the page when using the navigate plugin.
175   (patch by vird, pull request #1020)
176
177 - Fixed missing semicolons in the core library.
178   (reported by Michal Zglinski)

181## Flot 0.8.0 ##
182
183### API changes ###
184
185Support for time series has been moved into a plugin, jquery.flot.time.js.
186This results in less code if time series are not used. The functionality
187remains the same (plus timezone support, as described below); however, the
188plugin must be included if axis.mode is set to "time".
189
190When the axis mode is "time", the axis option "timezone" can be set to null,
191"browser", or a particular timezone (e.g. "America/New_York") to control how
192the dates are displayed. If null, the dates are displayed as UTC. If
193"browser", the dates are displayed in the time zone of the user's browser.
194
195Date/time formatting has changed and now follows a proper subset of the
196standard strftime specifiers, plus one nonstandard specifier for quarters.
197Additionally, if a strftime function is found in the Date object's prototype,
198it will be used instead of the built-in formatter.
199
200Axis tick labels now use the class 'flot-tick-label' instead of 'tickLabel'.
201The text containers  for each axis now use the classes 'flot-[x|y]-axis' and
202'flot-[x|y]#-axis' instead of '[x|y]Axis' and '[x|y]#Axis'. For compatibility
203with Flot 0.7 and earlier text will continue to use the old classes as well,
204but they are considered deprecated and will be removed in a future version.
205
206In previous versions the axis 'color' option was used to set the color of tick
207marks and their label text. It now controls the color of the axis line, which
208previously could not be changed separately, and continues to act as a default
209for the tick-mark color.  The color of tick label text is now set either by
210overriding the 'flot-tick-label' CSS rule or via the axis 'font' option.
211
212A new plugin, jquery.flot.canvas.js, allows axis tick labels to be rendered
213directly to the canvas, rather than using HTML elements. This feature can be
214toggled with a simple option, making it easy to create interactive plots in the
215browser using HTML, then re-render them to canvas for export as an image.
216
217The plugin tries to remain as faithful as possible to the original HTML render,
218and goes so far as to automatically extract styles from CSS, to avoid having to
219provide a separate set of styles when rendering to canvas. Due to limitations
220of the canvas text API, the plugin cannot reproduce certain features, including
221HTML markup embedded in labels, and advanced text styles such as 'em' units.
222
223The plugin requires support for canvas text, which may not be present in some
224older browsers, even if they support the canvas tag itself. To use the plugin
225with these browsers try using a shim such as canvas-text or FlashCanvas.
226
227The base and overlay canvas are now using the CSS classes "flot-base" and
228"flot-overlay" to prevent accidental clashes (issue 540).
229

420## Flot 0.7 ##
421
422### API changes ###
423
424Multiple axes support. Code using dual axes should be changed from using
425x2axis/y2axis in the options to using an array (although backwards-
426compatibility hooks are in place). For instance,
427
428```js
429{
430    xaxis: { ... }, x2axis: { ... },
431    yaxis: { ... }, y2axis: { ... }
432}
433```
434
435becomes
436
437```js
438{
439    xaxes: [ { ... }, { ... } ],
440    yaxes: [ { ... }, { ... } ]
441}
442```
443
444Note that if you're just using one axis, continue to use the xaxis/yaxis
445directly (it now sets the default settings for the arrays). Plugins touching
446the axes must be ported to take the extra axes into account, check the source
447to see some examples.
448
449A related change is that the visibility of axes is now auto-detected. So if
450you were relying on an axis to show up even without any data in the chart, you
451now need to set the axis "show" option explicitly.
452
453"tickColor" on the grid options is now deprecated in favour of a corresponding
454option on the axes, so:
455
456```js
457{ grid: { tickColor: "#000" }}
458```
459
460becomes
461
462```js
463{ xaxis: { tickColor: "#000"}, yaxis: { tickColor: "#000"} }
464```
465
466But if you just configure a base color Flot will now autogenerate a tick color
467by adding transparency. Backwards-compatibility hooks are in place.
468
469Final note: now that IE 9 is coming out with canvas support, you may want to
470adapt the excanvas include to skip loading it in IE 9 (the examples have been
471adapted thanks to Ryley Breiddal). An alternative to excanvas using Flash has
472also surfaced, if your graphs are slow in IE, you may want to give it a spin:
473
474    http://code.google.com/p/flashcanvas/
475
476### Changes ###
477
478 - Support for specifying a bottom for each point for line charts when filling
479   them, this means that an arbitrary bottom can be used instead of just the x
480   axis. (based on patches patiently provided by Roman V. Prikhodchenko)
481
482 - New fillbetween plugin that can compute a bottom for a series from another
483   series, useful for filling areas between lines.
484
485   See new example percentiles.html for a use case.
486
487 - More predictable handling of gaps for the stacking plugin, now all
488   undefined ranges are skipped.
489
490 - Stacking plugin can stack horizontal bar charts.
491
492 - Navigate plugin now redraws the plot while panning instead of only after
493   the fact. (raised by lastthemy, issue 235)
494
495   Can be disabled by setting the pan.frameRate option to null.
496
497 - Date formatter now accepts %0m and %0d to get a zero-padded month or day.
498   (issue raised by Maximillian Dornseif)
499
500 - Revamped internals to support an unlimited number of axes, not just dual.
501   (sponsored by Flight Data Services, www.flightdataservices.com)
502
503 - New setting on axes, "tickLength", to control the size of ticks or turn
504   them off without turning off the labels.
505
506 - Axis labels are now put in container divs with classes, for instance labels
507   in the x axes can be reached via ".xAxis .tickLabel".
508
509 - Support for setting the color of an axis. (sponsored by Flight Data
510   Services, www.flightdataservices.com)
511
512 - Tick color is now auto-generated as the base color with some transparency,
513   unless you override it.
514
515 - Support for aligning ticks in the axes with "alignTicksWithAxis" to ensure
516   that they appear next to each other rather than in between, at the expense
517   of possibly awkward tick steps. (sponsored by Flight Data Services,
518   www.flightdataservices.com)
519
520 - Support for customizing the point type through a callback when plotting
521   points and new symbol plugin with some predefined point types. (sponsored
522   by Utility Data Corporation)
523
524 - Resize plugin for automatically redrawing when the placeholder changes
525   size, e.g. on window resizes. (sponsored by Novus Partners)
526
527   A resize() method has been added to plot object facilitate this.
528
529 - Support Infinity/-Infinity for plotting asymptotes by hacking it into
530   +/-Number.MAX_VALUE. (reported by rabaea.mircea)
531
532 - Support for restricting navigate plugin to not pan/zoom an axis. (based on
533   patch by kkaefer)
534
535 - Support for providing the drag cursor for the navigate plugin as an option.
536   (based on patch by Kelly T. Moore)
537
538 - Options for controlling whether an axis is shown or not (suggestion by Timo
539   Tuominen) and whether to reserve space for it even if it isn't shown.
540
541 - New attribute $.plot.version with the Flot version as a string.
542
543 - The version comment is now included in the minified jquery.flot.min.js.
544
545 - New options.grid.minBorderMargin for adjusting the minimum margin provided
546   around the border (based on patch by corani, issue 188).
547
548 - Refactor replot behaviour so Flot tries to reuse the existing canvas,
549   adding shutdown() methods to the plot. (based on patch by Ryley Breiddal,
550   issue 269)
551   
552   This prevents a memory leak in Chrome and hopefully makes replotting faster
553   for those who are using $.plot instead of .setData()/.draw(). Also update
554   jQuery to 1.5.1 to prevent IE leaks fixed in jQuery.
555
556 - New real-time line chart example.
557
558 - New hooks: drawSeries, shutdown.
559

578
579 - highlight(s, index) was looking up the point in the original s.data instead

608   handler in Flot.
609
610 - Use closure trick to make inline colorhelpers plugin respect
611   jQuery.noConflict(true), renaming the global jQuery object (reported
612   by Nick Stielau).
613
614 - Listen for mouseleave events and fire a plothover event with empty
615   item when it occurs to drop highlights when the mouse leaves the
616   plot (reported by by outspirit).

640   0 (reported by adityadineshsaxena, Matt Sommer, Daniel Atos and some
641   other people, issue 301).
642
643 - Update colorhelpers plugin to avoid dying when trying to parse an

645
646
647
648## Flot 0.6 ##
649
650### API changes ###
651
652Selection support has been moved to a plugin. Thus if you're passing
653selection: { mode: something }, you MUST include the file
654jquery.flot.selection.js after jquery.flot.js. This reduces the size of
655base Flot and makes it easier to customize the selection as well as
656improving code clarity. The change is based on a patch from andershol.
657
658In the global options specified in the $.plot command, "lines", "points",
659"bars" and "shadowSize" have been moved to a sub-object called "series":
660
661```js
662$.plot(placeholder, data, { lines: { show: true }})
663```
664
665should be changed to
666
667```js
668  $.plot(placeholder, data, { series: { lines: { show: true }}})
669```
670
671All future series-specific options will go into this sub-object to
672simplify plugin writing. Backward-compatibility code is in place, so
673old code should not break.
674
675"plothover" no longer provides the original data point, but instead a
676normalized one, since there may be no corresponding original point.
677
678Due to a bug in previous versions of jQuery, you now need at least
679jQuery 1.2.6. But if you can, try jQuery 1.3.2 as it got some improvements
680in event handling speed.
681
682## Changes ##
683
684 - Added support for disabling interactivity for specific data series.
685   (request from Ronald Schouten and Steve Upton)
686
687 - Flot now calls $() on the placeholder and optional legend container passed
688   in so you can specify DOM elements or CSS expressions to make it easier to
689   use Flot with libraries like Prototype or Mootools or through raw JSON from
690   Ajax responses.
691
692 - A new "plotselecting" event is now emitted while the user is making a
693   selection.
694
695 - The "plothover" event is now emitted immediately instead of at most 10
696   times per second, you'll have to put in a setTimeout yourself if you're
697   doing something really expensive on this event.
698
699 - The built-in date formatter can now be accessed as $.plot.formatDate(...)
700   (suggestion by Matt Manela) and even replaced.
701
702 - Added "borderColor" option to the grid. (patches from Amaury Chamayou and
703   Mike R. Williamson)
704
705 - Added support for gradient backgrounds for the grid. (based on patch from
706   Amaury Chamayou, issue 90)
707
708   The "setting options" example provides a demonstration.
709
710 - Gradient bars. (suggestion by stefpet)
711 
712 - Added a "plotunselected" event which is triggered when the selection is
713   removed, see "selection" example. (suggestion by Meda Ugo)
714
715 - The option legend.margin can now specify horizontal and vertical margins
716   independently. (suggestion by someone who's annoyed)
717
718 - Data passed into Flot is now copied to a new canonical format to enable
719   further processing before it hits the drawing routines. As a side-effect,
720   this should make Flot more robust in the face of bad data. (issue 112)
721
722 - Step-wise charting: line charts have a new option "steps" that when set to
723   true connects the points with horizontal/vertical steps instead of diagonal
724   lines.
725
726 - The legend labelFormatter now passes the series in addition to just the
727   label. (suggestion by Vincent Lemeltier)
728
729 - Horizontal bars (based on patch by Jason LeBrun).
730
731 - Support for partial bars by specifying a third coordinate, i.e. they don't
732   have to start from the axis. This can be used to make stacked bars.
733
734 - New option to disable the (grid.show).
735
736 - Added pointOffset method for converting a point in data space to an offset
737   within the placeholder.
738 
739 - Plugin system: register an init method in the $.flot.plugins array to get
740   started, see PLUGINS.txt for details on how to write plugins (it's easy).
741   There are also some extra methods to enable access to internal state.
742
743 - Hooks: you can register functions that are called while Flot is crunching
744   the data and doing the plot. This can be used to modify Flot without
745   changing the source, useful for writing plugins. Some hooks are defined,
746   more are likely to come.
747 
748 - Threshold plugin: you can set a threshold and a color, and the data points
749   below that threshold will then get the color. Useful for marking data
750   below 0, for instance.
751
752 - Stack plugin: you can specify a stack key for each series to have them
753   summed. This is useful for drawing additive/cumulative graphs with bars and
754   (currently unfilled) lines.
755
756 - Crosshairs plugin: trace the mouse position on the axes, enable with
757   crosshair: { mode: "x"} (see the new tracking example for a use).
758
759 - Image plugin: plot prerendered images.
760
761 - Navigation plugin for panning and zooming a plot.
762
763 - More configurable grid.
764
765 - Axis transformation support, useful for non-linear plots, e.g. log axes and
766   compressed time axes (like omitting weekends).
767
768 - Support for twelve-hour date formatting (patch by Forrest Aldridge).
769
770 - The color parsing code in Flot has been cleaned up and split out so it's
771   now available as a separate jQuery plugin. It's included inline in the Flot
772   source to make dependency managing easier. This also makes it really easy
773   to use the color helpers in Flot plugins.
774
775## Bug fixes ##
776
777 - Fixed two corner-case bugs when drawing filled curves. (report and analysis
778   by Joshua Varner)
779
780 - Fix auto-adjustment code when setting min to 0 for an axis where the
781   dataset is completely flat on that axis. (report by chovy)
782
783 - Fixed a bug with passing in data from getData to setData when the secondary
784   axes are used. (reported by nperelman, issue 65)
785
786 - Fixed so that it is possible to turn lines off when no other chart type is
787   shown (based on problem reported by Glenn Vanderburg), and fixed so that
788   setting lineWidth to 0 also hides the shadow. (based on problem reported by
789   Sergio Nunes)
790
791 - Updated mousemove position expression to the latest from jQuery. (reported
792   by meyuchas)
793
794 - Use CSS borders instead of background in legend. (issues 25 and 45)
795
796 - Explicitly convert axis min/max to numbers.
797
798 - Fixed a bug with drawing marking lines with different colors. (reported by
799   Khurram)
800
801 - Fixed a bug with returning y2 values in the selection event. (fix by
802   exists, issue 75)
803
804 - Only set position relative on placeholder if it hasn't already a position
805   different from static. (reported by kyberneticist, issue 95)
806
807 - Don't round markings to prevent sub-pixel problems. (reported by
808   Dan Lipsitt)
809
810 - Make the grid border act similarly to a regular CSS border, i.e. prevent
811   it from overlapping the plot itself. This also fixes a problem with anti-
812   aliasing when the width is 1 pixel. (reported by Anthony Ettinger)
813
814 - Imported version 3 of excanvas and fixed two issues with the newer version.
815   Hopefully, this will make Flot work with IE8. (nudge by Fabien Menager,
816   further analysis by Booink, issue 133)
817
818 - Changed the shadow code for lines to hopefully look a bit better with
819   vertical lines.
820
821 - Round tick positions to avoid possible problems with fractions. (suggestion
822   by Fred, issue 130)
823
824 - Made the heuristic for determining how many ticks to aim for a bit smarter.
825
826 - Fix for uneven axis margins (report and patch by Paul Kienzle) and snapping
827   to ticks. (report and patch by lifthrasiir)
828
829 - Fixed bug with slicing in findNearbyItems. (patch by zollman)
830
831 - Make heuristic for x axis label widths more dynamic. (patch by
832   rickinhethuis)
833
834 - Make sure points on top take precedence when finding nearby points when
835   hovering. (reported by didroe, issue 224)
836
837
838
839## Flot 0.5 ##
840
841Timestamps are now in UTC. Also "selected" event -> becomes "plotselected"
842with new data, the parameters for setSelection are now different (but
843backwards compatibility hooks are in place), coloredAreas becomes markings
844with a new interface (but backwards compatibility hooks are in place).
845
846### API changes ###
847
848Timestamps in time mode are now displayed according to UTC instead of the time
849zone of the visitor. This affects the way the timestamps should be input;
850you'll probably have to offset the timestamps according to your local time
851zone. It also affects any custom date handling code (which basically now
852should use the equivalent UTC date mehods, e.g. .setUTCMonth() instead of
853.setMonth().
854
855Markings, previously coloredAreas, are now specified as ranges on the axes,
856like ```{ xaxis: { from: 0, to: 10 }}```. Furthermore with markings you can
857now draw horizontal/vertical lines by setting from and to to the same
858coordinate. (idea from line support patch by by Ryan Funduk)
859
860Interactivity: added a new "plothover" event and this and the "plotclick"
861event now returns the closest data item (based on patch by /david, patch by
862Mark Byers for bar support). See the revamped "interacting with the data"
863example for some hints on what you can do.
864
865Highlighting: you can now highlight points and datapoints are autohighlighted
866when you hover over them (if hovering is turned on).
867
868Support for dual axis has been added (based on patch by someone who's annoyed
869and /david). For each data series you can specify which axes it belongs to,
870and there are two more axes, x2axis and y2axis, to customize. This affects the
871"selected" event which has been renamed to "plotselected" and spews out
872```{ xaxis: { from: -10, to: 20 } ... },``` setSelection in which the
873parameters are on a new form (backwards compatible hooks are in place so old
874code shouldn't break) and markings (formerly coloredAreas).
875
876## Changes ##
877
878 - Added support for specifying the size of tick labels (axis.labelWidth,
879   axis.labelHeight). Useful for specifying a max label size to keep multiple
880   plots aligned.
881
882 - The "fill" option can now be a number that specifies the opacity of the
883   fill.
884
885 - You can now specify a coordinate as null (like [2, null]) and Flot will
886   take the other coordinate into account when scaling the axes. (based on
887   patch by joebno)
888
889 - New option for bars "align". Set it to "center" to center the bars on the
890   value they represent.
891
892 - setSelection now takes a second parameter which you can use to prevent the
893   method from firing the "plotselected" handler.
894
895 - Improved the handling of axis auto-scaling with bars.
896
897## Bug fixes ##
898
899 - Fixed a bug in calculating spacing around the plot. (reported by
900   timothytoe)
901
902 - Fixed a bug in finding max values for all-negative data sets.
903 
904 - Prevent the possibility of eternal looping in tick calculations.
905
906 - Fixed a bug when borderWidth is set to 0. (reported by Rob/sanchothefat)
907
908 - Fixed a bug with drawing bars extending below 0. (reported by James Hewitt,
909   patch by Ryan Funduk).
910
911 - Fixed a bug with line widths of bars. (reported by MikeM)
912
913 - Fixed a bug with 'nw' and 'sw' legend positions.
914
915 - Fixed a bug with multi-line x-axis tick labels. (reported by Luca Ciano,
916   IE-fix help by Savage Zhang)
917
918 - Using the "container" option in legend now overwrites the container element
919   instead of just appending to it, fixing the infinite legend bug. (reported
920   by several people, fix by Brad Dewey)
921
922
923
924## Flot 0.4 ##
925
926### API changes ###
927
928Deprecated axis.noTicks in favor of just specifying the number as axis.ticks.
929So ```xaxis: { noTicks: 10 }``` becomes ```xaxis: { ticks: 10 }```.
930
931Time series support. Specify axis.mode: "time", put in Javascript timestamps
932as data, and Flot will automatically spit out sensible ticks. Take a look at
933the two new examples. The format can be customized with axis.timeformat and
934axis.monthNames, or if that fails with axis.tickFormatter.
935
936Support for colored background areas via grid.coloredAreas. Specify an array
937of { x1, y1, x2, y2 } objects or a function that returns these given
938{ xmin, xmax, ymin, ymax }.
939
940More members on the plot object (report by Chris Davies and others).
941"getData" for inspecting the assigned settings on data series (e.g. color) and
942"setData", "setupGrid" and "draw" for updating the contents without a total
943replot.
944
945The default number of ticks to aim for is now dependent on the size of the
946plot in pixels. Support for customizing tick interval sizes directly with
947axis.minTickSize and axis.tickSize.
948
949Cleaned up the automatic axis scaling algorithm and fixed how it interacts
950with ticks. Also fixed a couple of tick-related corner case bugs (one reported
951by mainstreetmark, another reported by timothytoe).
952
953The option axis.tickFormatter now takes a function with two parameters, the
954second parameter is an optional object with information about the axis. It has
955min, max, tickDecimals, tickSize.
956
957## Changes ##
958
959 - Added support for segmented lines. (based on patch from Michael MacDonald)
960
961 - Added support for ignoring null and bad values. (suggestion from Nick
962   Konidaris and joshwaihi)
963
964 - Added support for changing the border width. (thanks to joebno and safoo)
965
966 - Label colors can be changed via CSS by selecting the tickLabel class.
967
968## Bug fixes ##
969
970 - Fixed a bug in handling single-item bar series. (reported by Emil Filipov)
971
972 - Fixed erratic behaviour when interacting with the plot with IE 7. (reported
973   by Lau Bech Lauritzen).
974
975 - Prevent IE/Safari text selection when selecting stuff on the canvas.
976
977
978
979## Flot 0.3 ##
980
981This is mostly a quick-fix release because jquery.js wasn't included in the
982previous zip/tarball.
983
984## Changes ##
985
986 - Include jquery.js in the zip/tarball.
987
988 - Support clicking on the plot. Turn it on with grid: { clickable: true },
989   then you get a "plotclick" event on the graph placeholder with the position
990   in units of the plot.
991
992## Bug fixes ##
993
994 - Fixed a bug in dealing with data where min = max. (thanks to Michael
995   Messinides)
996
997
998
999## Flot 0.2 ##
1000
1001The API should now be fully documented.
1002
1003### API changes ###
1004
1005Moved labelMargin option to grid from x/yaxis.
1006
1007## Changes ##
1008
1009 - Added support for putting a background behind the default legend. The
1010   default is the partly transparent background color. Added backgroundColor
1011   and backgroundOpacity to the legend options to control this.
1012
1013 - The ticks options can now be a callback function that takes one parameter,
1014   an object with the attributes min and max. The function should return a
1015   ticks array.
1016
1017 - Added labelFormatter option in legend, useful for turning the legend
1018   labels into links.
1019
1020 - Reduced the size of the code. (patch by Guy Fraser)
1021
1022
