                 \brief Pie series API for QtCommercial Charts
                 The pie series defines a pie chart which consists of pie slices which are QPieSlice objects.
                 The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices.
                 The actual slice size is determined by that relative value.
                 By default the pie is defined as a full pie but it can be a partial pie.
                 This can be done by setting a starting angle and angle span to the series.
