CoClasses that implement IChartRenderer
| CoClasses and Classes | Description |
|---|---|
| ChartRenderer | A chart renderer used to draw pie, bar, and stacked bar chart symbols. |
Remarks
The ChartRenderer requires a list of fields whose values are used to generate the pie slices, individual bars/columns, and stacked chart slices for each feature. Assign fields using IRendererFields. The chart type (pie, bar/column, or stacked bar/column) depends on the symbol assigned to ChartSymbol.
Set other properties for a ChartRenderer using this interface. Additionally, set properties for the chart symbol via IChartSymbol and also through interfaces specific to the chart symbol coclasses: PieChartSymbol, BarChartSymbol, and StackedChartSymbol. Also, use IPieChartRenderer to set properties specific to rendering with pie charts.
