110 | The pie series defines a pie chart which consists of pie slices which are QPieSlice objects. | |
|

111 | The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices. | |
|
|
112 | The actual slice size (span) is determined by that relative value. | |
|
|
113 | ||
|
|
114 | By default the pie is defined as full but it can be a partial pie. | |
|
|
115 | This can be done by setting a starting angle and angle span to the series. | |
