DXPieChart Class

The Chart view that visualizes data as pie series.

Declaration

@interface DXPieChart: DXChartBase

Remarks

The Chart displays a collection of series the series property stores. A series type defines how the chart shows data and how data representation behaves. Series that are compatible with the Pie Chart View should inherit the DXPieSeries class. The legend displays series’ and series points’ designations.

Refer to the Pie Chart guide to learn more about the Pie Chart.

Note

To display Cartesian series, use the DXChart view instead.
