+Flot plugin for rendering pie charts. The plugin assumes the data is
+coming is as a single data value for each series, and each of those
+values is a positive value or zero (negative numbers don't make
+any sense and will cause strange effects). The data values do
+NOT need to be passed in as percentage values because it
+internally calculates the total and percentages.
+
+* Created by Brian Medendorp, June 2009
+* Updated November 2009 with contributions from: btburnett3, Anthony Aragues and Xavi Ivars
+
+* Changes:
+ 2009-10-22: lineJoin set to round
+ 2009-10-23: IE full circle fix, donut
+ 2009-11-11: Added basic hover from btburnett3 - does not work in IE, and center is off in Chrome and Opera
+ 2009-11-17: Added IE hover capability submitted by Anthony Aragues
+ 2009-11-18: Added bug fix submitted by Xavi Ivars (issues with arrays when other JS libraries are included as well)
+
+
+Available options are:
+series: {
+ pie: {
+ show: true/false
+ radius: 0-1 for percentage of fullsize, or a specified pixel length, or 'auto'
+ innerRadius: 0-1 for percentage of fullsize or a specified pixel length, for creating a donut effect
+ startAngle: 0-2 factor of PI used for starting angle (in radians) i.e 3/2 starts at the top, 0 and 2 have the same result
+ tilt: 0-1 for percentage to tilt the pie, where 1 is no tilt, and 0 is completely flat (nothing will show)
+ offset: {
+ top: integer value to move the pie up or down
+ left: integer value to move the pie left or right, or 'auto'
+ },
+ stroke: {
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#FFF')
+ width: integer pixel width of the stroke
+ },
+ label: {
+ show: true/false, or 'auto'
+ formatter: a user-defined function that modifies the text/style of the label text
+ radius: 0-1 for percentage of fullsize, or a specified pixel length
+ background: {
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#000')
+ opacity: 0-1
+ },
+ threshold: 0-1 for the percentage value at which to hide labels (if they're too small)
+ },
+ combine: {
+ threshold: 0-1 for the percentage value at which to combine slices (if they're too small)
+ color: any hexidecimal color value (other formats may or may not work, so best to stick with something like '#CCC'), if null, the plugin will automatically use the color of the first slice to be combined
+ label: any text value of what the combined slice should be labeled
+ }
+ highlight: {
+ opacity: 0-1
+ }
+ }
+}
+
+More detail and specific examples can be found in the included HTML file.
