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