Maybe one extension of Jeff's answer.
The process works as long as x, y, and z are 2D arrays of the same size and
shape.
Hence, x and y don't have to form a rectangular grid.

And it makes a lot of sense.

I think LABELPAD is the padding between the label and the tick.
What I would like to control is the distance between the label and the
y-axis itself.
This is desired when you do multiple subplots and you want all ylabels to
align nicely; they may differ
depending on the numbers along the yticks.

You started a discussion about dpi on the figures.
Yet here you claim that 1pt = 1/72 inch.
Is that always the case?
And why? How does mpl figure that out, if there are also different dpi

The plot thickens...

Hello -
As reported in an earlier post, when setting aspect ratio, the axis limits
don't get updated correctly it seems. Or maybe I have to make another
function call. Very easy example:
from pylab import *
ax = subplot(211)
plot([1,2,3])
ax.set_aspect('equal',adjustable='datalim')
print ax.get_x

As a workaround, can you just turn the axis box and ticks off?
xticks([])
yticks([])
setp(ax,'frame_on',False)
Or does that give the same problem?

d with 0.91.2, the cm fonts are not included, which I

To be honest, I think the native array storage order matters a lot.
When you have a large dataset, transposing the matrix is not a cheap command.
