on what are you drawing ?

you must drawing on a drawing area !!...

so in the _Draw event of the drawing area!


or at least you setup the cached property of the drawing area to true and  :

DIM mychart AS NEW Chart (not writte in the help but inserted)
mychart.Count = 3
mychart[0].Values = [1.0, 2.0, 3.0]
mychart.Headers.Values = ["tic", "tac", "toes"]
mychart.Legend.Visible = TRUE
mychart.Style = ChartType.Pie
mychart.Width = DrawingArea1.W
mychart.Height = DrawingArea1.H
Draw.begin(DrawingArea1)
mychart.Draw
Draw.end
