 something like R's layout command, which allows you to nearly
 arbitrarily arrange the subplots of a figure. this command is much
 more general than subplot since it does not restrict you to square
 arrangements of figure subplots.

 for examples, check out these figures/examples:

 1. source code of complex layout:
 http://rgraphics.limnology.wisc.edu/rmargins_layout.php
 (the associated graph it produces is here:
 http://rgraphics.limnology.wisc.edu/images/layouts/rmargins_layout_thumb.png)

 2. a tutorial on complex layouts with this command:
 http://www.statmethods.net/advgraphs/layout.html
 in particular, see:
 http://www.statmethods.net/advgraphs/images/layout3a.png where a
 complex layout which is currently not possible with subplot is made.

 a command like R's layout would be a tremendously helpful addition to
 matplotlib, in my opinion. it will prevent the need for annoying
 manual postprocessing of figures into these layouts using tools like
 Illustrator, since these figures could be generated programmatically
 instead, which much more precision.

 as far as i know, this cannot be done in matplotlib right now, without
 plotting your own axes (using some combination of axes grid toolkit
 and raw axes plotting.)

 if anyone out there has written some kind of wrappers that do
 something like the layout command, i would love to know about it. if
 it's still in testing and not part of the current matplotlib, i'd be
 more than happy to beta test this for anyone and try it on many
 examples.
   
Hi Per,

I wrote two things that may be of interest to you.

This first is mplsizer, based on the wx layout model, and works live
(with a figure open in a GUI) as well as for saving to disk. See the
demo directory for, well, some demos. I haven't been using this too much
lately, but it still works as well as it ever did AFAIK. There is a
trivial bit of documentation and a copy of the source at
http://github.com/astraw/mplsizer

The second is svg_stack. This is used as a post-processing step that
requires saving my figures as svg files and then composing them with
this tool. There is some minimal documentation and the source at
http://github.com/astraw/svg_stack . The nice thing with svg_stack is
that you can use svg files from other sources (i.e. not just
matplotlib). Also, everything can be manually adjusted in Inkscape,
which itself has nice command-line export to .png and .pdf capabilities.

Any interest in merging this in as an mpl_toolkit?

It already is. :) Any interest in writing docs and advertising it?

Well, first I'll use it :). I can advertise if I and up using it a lot.
