Hi all,
I've recently implemented a simple equal area (Lambert) projection in
mpl, using two polar Axes (to draw each hemisphere), and this
currently works fine to draw lines and points, since I'm transforming
the points in my own code, from 3d-polar to 2d-projected-polar
co-ordinates, and then pl

Hi all,
I'm playing around with plotting with the Lambert transform. I want to
only plot one hemisphere at a time.
I see that if I create the appropriate axes:
ax = plt.subplot(111, projection='lambert')
the resulting axis object's ax.get_xlim() and ax.get_ylim() methods
give the limits in rads

obvious that it can be used to nest one grid within another, as
gridspec can. Can
