    Chart: IChart;
Begin
    Rep := PrxReport.ActiveReport;
    TabS := (Rep.ActiveSheet As IPrxTable).TabSheet;
    pChart := TabS.Objects.Item(0).Extension As IPrxChart;

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 this button displays only the secondary chart in black and white.
