Occurs just before the chart graphic is painted. Write an OnDrawing event handler to take specific action when the chart graphic is about to paint. If the event handler sets the DoDraw parameter to False, the chart graphic will not be painted. The OnDraw event also allows you to do custom painting before the chart graphic has been painted.
