Delphi

public 
  procedure Draw( const Canvas: TCanvas; ARect: TCanvasRect); overload; virtual; 
 

Parameters

Canvas

Type: TCanvas

Canvas to draw on

ARect

Rectangle in canvas to draw itself

The Draw method first calls the  OnDrawing event, which signals that it is about to draw and allows users to stop the drawing before it occurs. Then, it calls the protected  InternalDraw method to actually do the drawing. Finally, it calls the OnDraw event to signal the end of drawing of the chart graphic.
