There's an IDL draw widget where I'm defining a region of interest, and depending on that region of interest my program computes an autocorrelation and then plots the results. So the shape of my plot will depend on the shape of the ROI, and since I'm not actually inputting numbers for this ROI but clicking and dragging in that window to create a
rectangle, I don't have a way of knowing what those dimensions are before the plot (so I can't hardcode an aspect ratio ahead of time).

Well, you can continue to believe this if you like. Good
luck with this!

But, if you are the one creating the ROI, and you seem to have
some notion of the xrange and yrange, then I'd be willing to
bet some money you have enough information to set the aspect
ratio of the plot correctly. :-)

Cheers,

David
