/* Flot plugin for rendering pie charts.

Copyright © 2007-2013 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.

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')
                        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
                }
        }
}
