Defines the method signature for a chart drawing event handler. The Canvas parameter contains the canvas that is about to painted on, and the ARect parameter specifies where on the canvas the chart will be drawn. Use a drawing event handler to paint to the canvas before the chart is painted or to stop the drawing of the chart. By setting DoDraw to False, the chart drawing can be stopped.
