Looks interesting, I'll have to take a look when I get a chance. Two
early questions:

1) How does this relate to the functionality present in your axes_grid toolkit?

2) Do you plan on checking this into mpl trunk (still as a mpl_toolkit module)?

axes_grid toolkit is more flexible and is mainly meant to work with
axes with images. gridspec is more for normal axes.

As a matter of fact, the multiple axes created by axes_grid toolkit
usually occupies the area of a single subplot. So, to me, axes_grid
toolkit is something that allows me to divide the area of a single
subplot for multiple images, and gridspec is a replacement of the
subplot.

Not at this moment. But, will consider if there is enough interest.

This looks sufficiently general and useful that we may simply want it
to live in the main tree (not as a toolkit) and have subplot2grd
helper functionality available directly from pyplot.

This is really awesome! Thanks for all the time and hard work, JJ.

Very interesting indeed. If I may comment on the usability, I wish function
gridspec.subplot could become directly a method of Gridspec. The current example:

gs = gridspec.GridSpec(3, 3)
ax1 = gridspec.subplot(gs[0, :])
ax2 = gridspec.subplot(gs[1,:-1])
ax3 = gridspec.subplot(gs[1:, -1])
ax4 = gridspec.subplot(gs[-1,0])
ax5 = gridspec.subplot(gs[-1,-2])

could be written in a much simpler way then, such as:

gs = gridspec.GridSpec(3, 3)
ax1 = gs[0, :]
ax2 = gs[1,:-1]
ax3 = gs[1:, -1]
ax4 = gs[-1,0]
ax5 = gs[-1,-2]

I would LOVE it!

+1 for getting these functionnalities straight in matplotlib: subplot management
always take a decent part of my scripts...

Cheers,

Okay.
I'll merge this into the main tree and commit.

I'm inclined to leave the GridSpec as it is and I prefer to have a
separate class for this (if we go for it). My inclination is to modify
subplot2grid to return such an instance. e.g.,

grid = gridspec.subplot2grid((2,2))
ax1 = grid[0,:]

The functionality of the gridspec is now merged into the matplotlib.
The updated documentation can be found in

http://matplotlib.sourceforge.net/trunk-docs/users/gridspec.html
