[Matplotlib-users] Multiple Projections On Same Axes

[T J]

When I read the transformations documentation:

http://matplotlib.org/devel/add_new_projection.html#creating-a-new-projection

it seems like each projection is tied to an Axes instance. How might I go
about plotting two different projections on the same axes? Let's just
assume that the actual axes each projection draws is exactly same and all
that differs between to the two is how data is mapped to axis coordinates.

twinx()/twiny() I think is your best bet. It isn't a fully generic
solution, but I think it addresses most needs.

Ok, sounds like I'll have to copy what those do, as I'm not planning on
working with Cartesian or even curvilinear coordinates.

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).
