thanks for your help! yes, I do get the plotarea position by following fomula now: top=graphic.height-(xscale.height+plotarea.height)+devx left=yscale.width+devy Additionary numbers, devx and devy, must be added for fix the result, so I want to get it by: top= xscale.top - plotarea.height left= yscale.left + yscale.width but the results are terrible mistake, why? Does xscale.position means the absolute position in panels but not the relative position in the graphic control?

how to get the plot area's position property of a wavegraph in labview 7.1, I can only find the size property.
