Re: [matplotlib-devel] Alternative way of specifying plot layout

[Nicolas P. R. <Nic...@in...>]

Great ! Thanks for setting this up. One comment, it would be great to have a README.rst in the directory to have abstract of all MEPS at once in github (I can make a PR).


I've started working on MEP28 (https://github.com/rougier/matplotlib/blob/MEP28/doc/devel/MEP/MEP28.rst). I intend to make a PR once it is a bit more polished or should I make a PR right now to initiate the discussion on the PR ? (It is not clear to me if the preferred medium for discussion is the mailing list or the PR comments).

It would also allow us to return the plotting axes separate from the colorbar axes, which is how axes_grid1 does it, and it is very nice that way.
