CircleInfo: IChartCircleInfo;
The CircleInfo property enables the user to determine pie chart parameters.
Use the IChartCircleInfo interface to work with available parameters.
This example assumes that there is the Chart object of the IChart type. The chart must be a pie chart. If required, the chart can be transformed into a pie chart by executing the command: Chart.Type := 5 As ChartType.
Sub Circle;
Var
Chart: IChart;
Begin
Chart.CircleInfo.FixedRadius:= 30;
End Sub Circle;
After executing the example the radius of the pie chart is equal to 30 millimeters.
