Occurs right before the  LeftAxis is drawn. Use the OnDrawingLeftAxis event to paint behind the LeftAxis before it is drawn over top. By setting the DoDraw parameter to False, you can also prevent the LeftAxis from drawing. The Canvas parameter contains the canvas where the LeftAxis will be drawn, and the ARect parameter specifies where on the canvas the LeftAxis will be drawn.

Namespace: RSChartPanel

expandingSyntax

Delphi

public
  property OnDrawingLeftAxis: TRSChartDrawingEvent read GetOnDrawingLeftAxis write SetOnDrawingLeftAxis;
 

Value

Type: TRSChartDrawingEvent

expandingExamples

The following code uses the OnDrawingGradient event handler to prevent the gradient from being drawn. The same principle applies here:

Delphi

procedure TForm1.RSChartPanel1DrawingGradient(Sender: TObject;
   const Canvas: TCanvas; ARect: TRect; var DoDraw: Boolean);
 begin
      DoDraw := False;
 end;
