Detailed Description
An item to render a pie chart.
This item will render a Pie chart based on the valueSources supplied to it. By default it will set indexingMode to IndexSourceValues, meaning that it will use the individual values of the valueSources to render sections of the chart.
Usage example

Multiple Value Sources
Multiple valueSources are rendered as consecutive pie charts in the same item. The first valueSource will become the outermost circle and consecutive valueSources will be rendered as continuously smaller circles. When rendering multiple value sources, filled will only affect the last value source. All other value sources will be rendered according to thickness, with spacing amount of space between them.
Definition at line 50 of file PieChart.h.
Property Documentation
|
readwrite |
Sets a colour to use to fill remaining space on the pie.
The default is transparent.
Definition at line 87 of file PieChart.h.
|
readwrite |
Whether to use a filled pie or not.
If true, the last pie rendered will be rendered as a filled circle. The default is false.
Definition at line 69 of file PieChart.h.
|
readwrite |
The starting angle of the arc used for the entire pie.
When set, instead of rendering a full circle, the pie will be rendered as an arc. The default is 0.
Definition at line 94 of file PieChart.h.
|
read |
The range of values to display in this PieChart.
When set to "automatic", the values will be divided across the entire chart.

- RangeGroup
Definition at line 62 of file PieChart.h.
|
readwrite |
Smooth the ends of pie sections.
When true, this will try to smooth the ends of sections. This works best when filled is false. The default is false.
Definition at line 109 of file PieChart.h.
|
readwrite |
The amount of spacing between pies when rendering multiple value sources.
The default is 0.
Definition at line 81 of file PieChart.h.
|
readwrite |
The thickness of an individual pie, in pixels.
If filled is set, this is ignored for the last pie. The default is 10px.
Definition at line 75 of file PieChart.h.
|
readwrite |
The end angle of the arc used for the entire pie.
When set, instead of rendering a full circle, the pie will be rendered as an arc. The default is 360.
