36 35 \class QPieSeries
37 36 \brief Pie series API for QtCommercial Charts
38 37
39 38 The pie series defines a pie chart which consists of pie slices which are defined as QPieSlice objects.
40 39 The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices.
41 40 The actual slice size is determined by that relative value.
42 41
43 42 Pie size and position on the chart is controlled by using relative values which range from 0.0 to 1.0
44 43 These relate to the actual chart rectangle.
45 44
46 45 By default the pie is defined as a full pie but it can also be a partial pie.
47 46 This can be done by setting a starting angle and angle span to the series.
48 47 Full pie is 360 degrees where 0 is at 12 a'clock.
49 48
50 49 See the \l {PieChart Example} {pie chart example} to learn how to create a simple pie chart.
