Re: [Matplotlib-users] Multiple Projections On Same Axes

[Benjamin R. <ben...@ou...>]

Well, the way those work is essentially overlay one axes object over
another along with some extra fanagiling to link up the shared axis and put
ticks on opposing sides. If your projection is already available as an
axes, then you are good to go that way. However, it sounds what you want is
to have some things follow one transform while others follow another? That
is certainly doable, it is just a question of bookkeeping.

I would check to see if the axis_artist1 toolkit supplies what you need (or
at least some of it).
