\class QPieSeries
\brief Pie series API for QtCommercial Charts
Jani Honkonen
Pie doc updates
 r952 The pie series defines a pie chart which consists of pie slices which are defined as QPieSlice objects.
Jani Honkonen
More documentation for pie
 r320 The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices.
Jani Honkonen
Review corrections for pie
 r386 The actual slice size is determined by that relative value.
Jani Honkonen
More documentation for pie
 r320
Jani Honkonen
Pie doc updates
 r952 Pie size and position on the chart is controlled by using relative values which range from 0.0 to 1.0
These relate to the actual chart rectangle.
By default the pie is defined as a full pie but it can also be a partial pie.
Jani Honkonen
More documentation for pie
 r320 This can be done by setting a starting angle and angle span to the series.

Pie doc updates
 r952 Full pie is 360 degrees where 0 is at 12 a'clock.
