|
Jani Honkonen
|
r952 | The pie series defines a pie chart which consists of pie slices which are defined as QPieSlice objects. | ||
|
Jani Honkonen
|
r320 | The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices. | ||
|
Jani Honkonen
|
r386 | The actual slice size is determined by that relative value. | ||
|
Jani Honkonen
|
r320 | |||
|
Miikka Heikkinen
|
r2494 | Pie size and position on the chart is controlled by using relative values which range from 0.0 to 1.0. | ||
|
Jani Honkonen
|
r952 | 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
|
r320 | This can be done by setting a starting angle and angle span to the series. | ||
|
Jani Honkonen
|
r952 | Full pie is 360 degrees where 0 is at 12 a'clock. | ||
