| * Released under the MIT license by IOLA, December 2007. | |

| */ | |
| // first an inline dependency, jquery.colorhelpers.js, we inline it here | |

| /* Plugin for jQuery for working with colors. | |
| * | |
| * Version 1.1. | |
| * | |
| * Inspiration from jQuery color animation plugin by John Resig. | |
| * | |
| * Released under the MIT license by Ole Laursen, October 2009. | |
| * | |
| * Examples: | |
| * | |
| * $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString() | |
| * var c = $.color.extract($("#mydiv"), 'background-color'); | |
| * console.log(c.r, c.g, c.b, c.a); | |
| * $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)" | |
| * | |
| * Note that .scale() and .add() return the same modified object | |
| * instead of making a new one. | |
| * | |
| * V. 1.1: Fix error handling so e.g. parsing an empty string does | |
| * produce a color rather than just crashing. | |

| 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. | |
