How can i get (with vb.net) the width and the height of the plotarea in pixel when i have set the autosize feature?
F.e. i tried to get the margin: RadChart1.PlotArea.Appearance.Dimensions.Margins.Right.Value
But i get always the same value f.e. when i switch on / of the legend ... which changes the margins ...
Thanks and best regards

Hi Chris,
RadChart performs the layout calculations only once. RadChart exposes two events - BeforeLayout and PrePaint. The former is fired before the layout is calculated, while the latter is fired after that and before the actual image rendering occurs. That said, you can retrieve the plot area size in the PrePaint event handler. However, you will not be able to take advantage of this size in scenarios related to RadChart layout, as it has already been calculated and any updates in chart elements size and position will not be applied.
