56 | 56 | QLegend is a graphical object, whics displays legend of the chart. Legend state is updated by QChart, when |

|
59 | 59 | User isn't supposed to create or delete legend objects, but can reference it via QChart class. |

|
38 | 38 | \brief Pie series API for QtCommercial Charts |
|
39 | 39 | |
|
40 | 40 | The pie series defines a pie chart which consists of pie slices which are defined as QPieSlice objects. |
|
41 | 41 | The slices can have any values as the QPieSeries will calculate its relative value to the sum of all slices. |
|
42 | 42 | The actual slice size is determined by that relative value. |
|
43 | 43 | |
|
44 | 44 | Pie size and position on the chart is controlled by using relative values which range from 0.0 to 1.0 |
|
45 | 45 | These relate to the actual chart rectangle. |
|
46 | 46 | |
|
47 | 47 | By default the pie is defined as a full pie but it can also be a partial pie. |
|
48 | 48 | This can be done by setting a starting angle and angle span to the series. |
|
49 | 49 | Full pie is 360 degrees where 0 is at 12 a'clock. |
|
50 | 50 | |
|
51 | 51 | See the \l {PieChart Example} {pie chart example} or \l {DonutChart Example} {donut chart example} to learn how to use QPieSeries. |
