// Summary:
// This class abstracts the view of a pie series point.This class is a kind of
// CXTPChartSeriesPointView.
// 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.
