would like isotropic axis scaling

Hi,
It would be usefull to have the option to make a chart istropic (chart aspect ratio in real coords space == chart aspect ration in pixel coords). For example on some charts ,i sometimes want the ratio of
A/B == C/D
where A = (chart.Axis.Left.Maximum - chart.Axis.Left.Minimum)
B = (chart.Axis.Bottom.Maximum - chart.Axis.Bottom.Minimum)
C = char.Axis.Left.CalcYPosValue(A)
D = char.Axis.Bottom.CalcXPosValue(B)
Moreover, I also need to be able to resize the parent window of the chart
keeping this ration constant. My reason for doing this is that if a contour
is a circle (for example section of a cylinder) I need (or customers need) to see it as a circle so that i can visually check that the contour is as expected. This would be really useful to have, as we have many cases where an engineer wants to look at a cross-section through a grid of surface data and would like to see the real cross section shape that was independent of the current display window size. I can see uses of this as and inspection tool for point clouds (reverse engineering, rapid prototyping and CMM)
Thanks
Andrzej
