  Hello,
  
  I want change some properties of a TChart/TfrxChartView object in the code section of the report: here properties of the section 'tools'...
  
  In the charteditor I can change/add/delete 'tools'-objects like the 'colorband'-tool..., but I want to change it in the code section and don't know the right property names.
  
  I can do it, if I use (in Delphi) a TeeChart component like this

  type
    TForm1 = class(TForm)
      Chart1: TChart;
      Series1: TBarSeries;
      ChartTool1: TColorBandTool;
      TrackBar1: TTrackBar;
      procedure FormShow(Sender: TObject);
      procedure TrackBar1Change(Sender: TObject);
    private
    public
    end;
  
  ...
  
  procedure TForm1.TrackBar1Change(Sender: TObject);
  begin
    ChartTool1.Gradient.Colors.Item[0].Offset:=0;
    ChartTool1.Gradient.Colors.Item[1].Offset:=TrackBar1.Position / 100;
    ChartTool1.Gradient.Colors.Item[2].Offset:=1;
  
    ChartTool1.Gradient.StartColor:=clGreen;
    ChartTool1.Gradient.MidColor:=clYellow;
    ChartTool1.Gradient.EndColor:=clRed;
  end;
  

  
  How can I do this in the code section?

  procedure Page1OnBeforePrint(Sender: TfrxComponent);
  begin
    Chart1.ChartTool1...???
  end;
  

  
  Thanks
