C++

delphi

procedure TMyForm.cdAreaGetSeriesPointDrawParameters(Sender: TdxChartCustomDiagram;
  AArgs: TdxChartGetSeriesPointDrawParametersEventArgs);
var
  ASimpleDrawParameters: TdxChartSimpleSeriesPointDrawParameters;
begin
  if AArgs.SeriesPoint.Argument = 'English' then
  begin
    if AArgs.DrawParameters.ClassType <> TdxChartSimpleSeriesPointDrawParameters then Exit;
    ASimpleDrawParameters := AArgs.DrawParameters as TdxChartSimpleSeriesPointDrawParameters;
    ASimpleDrawParameters.FillOptions.BeginUpdate;
    ASimpleDrawParameters.FillOptions.Color := TdxAlphaColors.LightCyan;

    ASimpleDrawParameters.FillOptions.Mode := TdxFillOptionsMode.Hatch;
    ASimpleDrawParameters.FillOptions.HatchStyle := TdxFillOptionsHatchStyle.ForwardDiagonal;
    ASimpleDrawParameters.FillOptions.EndUpdate;
  end;
