// Summary:
|
|
// This class abstracts the view of a pie series.This class is a kind of
|
|
// CXTPChartSeriesView.
|
|
// Remarks:
|
|
// A pie chart (or a circle graph) is a circular chart divided into sectors,
|
|
// illustrating percents. In a pie chart, the arc length of each sector (and
|
|
// consequently its central angle and area), is proportional to the quantity
|
|
// it represents. Together, the sectors create a full disk.
