Interesting, I didn't even know about apply_aspect. And it does indeed work
for my case.
Any reason not to call that at the end of the set_aspect function? Eric
Firing probably knows.
I think the aspect ratio functionality is very cool.
You can set all kind of preferences, including an arbitrary aspect ratio.
I don't know any other plotting packages that does it so well.
Whether the code is complex or not I don't know.
But there is a lot of crap to have to keep track off.
