Chart.Draw (gb.chart)

Sub Draw ( )

Renders the chart object in a (DrawingArea) control. 

Private $MyChart as Chart

Public Sub MyDrawingArea_Draw()
  
  ' do any on the fly stuff here, e.g reset the Height and Width
  
  $MyChart.Draw

End

(Now, somewhere else you need (AFAICT) to call MyDrawingArea.Refresh!)
