Sub ChangeBlackAndWhite;
Var
    Rep: IPrxReport;
    TabS: ITabSheet;
    pChart: IPrxChart;
    Chart: IChart;
Begin
    Rep := PrxReport.ActiveReport;
    TabS := (Rep.ActiveSheet As IPrxTable).TabSheet;
    pChart := TabS.Objects.Item(0).Extension As IPrxChart;
    Chart := pChart As IChart;
    Chart.MakeBlackAndWhite;
    TabS.Recalc;

Fore.NET Example

This example assumes that there is the Chart object of the IChart type. The chart must be a pie chart type with a secondary pie chart or histogram. If required, the chart can be transformed into the required type by executing the command: Chart.Type := 10 As ChartType.

Imports Prognoz.Platform.Interop.Metabase;
Imports Prognoz.Platform.Interop.Chart;

Private Sub button1_Click(sender: System.Object; e: System.EventArgs);
Var
    Chart : IChart;
Begin
    Chart := UiChartNet1.ChartUi.Chart;
    Chart.CircleInfoEx.ShowMode:= ChartSecondaryShowMode.cssmOnlySecondary;
    Chart.MakeBlackAndWhite();
End Sub;

Clicking the button displays only the secondary chart in black and white format.
