"Split" axes

I'm trying to make 2D figures with "split" axes with matplotlib. I've
included an example, produced in Igor Pro. Is such a thing possible?
Before diving into the inner guts of plot and axes drawing, I thought
I would ask if it's 1, possible and 2, already solved.

If this is a FAQ or otherwise documented, I'd be happy for a link.

Thanks!
