Coloring
In Default color mode, the Pie dashboard item colors its segments in the following way:
If the Pie dashboard item contains measures (the Values section) and series dimensions (the Series section), only values corresponding to different measures are colored by hue.
If the Pie dashboard item contains arguments (the Arguments section), different argument values are colored by hue.
To access Pie color options in code, use the ChartDashboardItemBase.ColoringOptions property.
