/* Flot plugin for rendering pie charts.

Copyright (c) 2007-2014 IOLA and Ole Laursen.
Licensed under the MIT license.

The plugin assumes that each series has a single data value, and that each
value is a positive integer or zero.  Negative numbers don't make sense for a
pie chart, and have unpredictable results.  The values do NOT need to be
passed in as percentages; the plugin will calculate the total and per-slice
percentages internally.

* Created by Brian Medendorp

* Updated with contributions from btburnett3, Anthony Aragues and Xavi Ivars

The plugin supports these options:

    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')
                 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
            }
        }
    }
