jQuery Sparkline Plugin ChangeLog
http://omnipotent.net/jquery.sparkline/


1.5 26/February/2010

+ Very small pie slices could fill the whole chart in IE
Thanks to Peter Doel for catching and fixing it

+ Added chartRangeClip option to force values outside of chartRangeMin/chartRangeMax
to be clipped

+ Added chartRangeMinX/chartRangeMaxX for line charts

+ Allow chart types other than line chart to be used as composites.

+ colorMap may now pass null as a colour to omit that bar from display entirely

+ colorMap may now be passed as an Array of values allowing the colour of each
bar to be specified individually, rather than mapping by value

+ Added nullColor option to bar charts to force null values to show up as a thin line

+ Performance improvements with IE


1.4.3 14/September/2009

+ Updated default pie chart colours - Thanks Liel Dulev

+ Null values can now be supplied to line and bar charts
(use 'null' as the value) - Thanks to Ed Blachman for 
testing/debugging help

+ Added colorMap option for bar charts

+ Added lineWidth option for line charts - Can be an integer or a float
(try 1.5 or 2)


1.4.2 25/April/2009

+ Fixed rendering of circular spots on line charts
for Internet Explorer 8


1.4.1 27/March/2009

+ Fixed minor off-by-1-pixel display glitch with IE

+ Improved compatibilty with jQuery 1.3 which could cause some sparklines
not to be rendered in certain situations


1.4 25/February/2009

+ Added the box plot chart type

+ Fixed a canvas rendering issue that would display some charts with
fuzzy lines

+ Fixed error in bar charts which would causes bars to be too short.

+ Couple of other minor bug fixes


1.3 25/January/2009

+ Sparklines can't be automatically displayed into hidden elements (ie. 
with display:none) - Added a $.sparkline_display_visible() function
to render any sparklines that were generated while a tag was
hidden

+ Fixed positioning issues where sparklines would be displayed a few
pixels offset from their containers in some browsers

+ Made a first attempt at IE8 support.  IE8 beta 2 seems to
have some vml related bugs though so having more than one sparkline
on a line doesn't work correctly, nor do the markers on line charts

+ Misc other bug fixes

+ Updated the web site with a new look


1.2.1 24/November/2008

+ Pie chart bug fixes:  Divide by zero error resolved
and IE rendering issue if a pie slice is equal to 0
Thanks to Hubert Mandeville for a patch fixing both issues


1.2 - 19/November/2008

+ Fixed positioning of min/max line markers for fixed range graphs
(thanks to Stéphane Busso)

+ Fixed rendering of bar charts with negative values

+ All values in a bar chart have a height now (min values used to 
have height = 0)

+ Added zeroColor option for bar charts which allows assignment of
a different color for values that are equal to zero

+ Line charts can now specify both x and y values if required in one of 
three ways:
a) Inline with HTML with values interleaved:
x1:y1,x2:y2,x3:y3
eg. <span class="linechart">1:10,5:8,7:10</span>
b) Programatically using an x,y array for each value:
$('#mychart').sparkline([ [1,10], [5,8], [7,10] ]);
c) Programatically using a separate array for the x values:
$('#mychart').sparkline( [10,8,10], { xvalues: [1,5,7] });

+ Added chartRangeMin and chartRangeMax to line, bar and discrete graphs
This allows you to artificialy fix the min/max values for the graph
so that multiple graphs can share the same scale.

+ Added defaultPixelsPerValue option to specify how many pixels wide
each value should be in a dynamically sized line graph

+ Added offset option to piecharts - Takes a positive or negative degree
offset to start drawing the chart from.


1.1 - 29/July/2008

+ Added minSpotColor and maxSpotColor to line charts - If set then spot
markers are placed at the cordinates of the minimum and maximum values.

+ Added normalRangeMin and normalRangeMax to line charts - If set then
a normalRangeColor band will be drawn on the graph

+ Added chart compositing - Applying another chart to a DOM element with 
an option of composite: true will cause the second (or more) chart to be 
overlayed on the first rather than replacing it.  

+ Added optional colorMap option to tristate chart - This allows specific 
colors to be supplied for specific values

+ Added discrete chart type - Uses fixed size discrete vertical lines to mark
each values in a series

+ Added bullet graph type - Implementation of Stephen Few's bullet graphs

+ Added pie chart type

+ Improved auto height option to match the line height of the containing
element

+ Fixed some off by one positioning errors

+ Reduced the default radius of spot markers from 2 to 1.5 pixels


1.0 - 17/July/2008

+ Initial Release
