The Pie graph or series is used to represent data as sectors or slices of a circular
pie. It has only one mandatory series
component, Pie, whose data are used to determine the relative sizes
of the pie slices. It also has an optional component called LabelMember
whose data may be used as the mark labels for the pie slices.
The color and explosion of a specific pie slice can be customized with the Series
Piece Editor that can be opened by left clicking on the pie slice while
keeping the Shift key pressed.
Multiple pie slices can be grouped into the so-called "Other" slice if
their values in the Pie components are below a specific threshold. The OtherSliceType,
OtherSliceValue, and OtherSliceText properties respectively specify
the type and value of the threshold, and the text label for the Other
