It _does_ change the aspect ratio, as desired, but since the tick marks and labels are applied in the original plot call, they end up smushed on the reformatted plot. I could fix this by redoing the tick marks and labels, but this is starting to be a poor use of time.

Doing it afterward hadn't occurred to me, and it wasn't clear how to do it upfront because every plot is different. So that should work. Still, it would be nice not to add two extra steps.

I'll think about a way to do that with "dimensions," although in this case I'm letting IDL pick the axis range and dimensions has to be specified in the original call.

Just use ASPECT_RATIO keyword in the original call.
