you can add more space.

I noticed that colorbar.Colorbar treats segmentation via *boundaries*

It already has this. You can pass in a custom locator or set of tick

I have found a solution. I'm not sure if it's good or intended but the
following works:
for label in xax.get_ticklabels():
label.set_rotation(45)
label.set_horizontalalignment('left')
This is fully intended. Maybe you

See Subject. I use matplotlib, scipy, numpy and possibly one other
module. If I go to the control panel, I only see numpy listed. Why? I

and scipy be uninstalled?

On my Macbook Pro I use Python 2.6 as provided by the Enthought Python
Distribution. I ran into some problem with Axes3D so I decided to
upgrade to the latest version from source. While trying that I got a
similiar error message as discussed in
Are you on OSX 10.5 or 10.6? I'm asking because it's important for
others when you're on 10.5 because you're using gcc-4.0 then, while

I'm running Mac OS X 10.5.8.
Ok, that explains why it works to flawlessly. When you would be on
10.6, you would probably run into the problem I mentioned, because the

I would like to have the colorbar displaying the same color scaling
regardless of the data input.
This /should/ be feasible with .contourf(.., vmin=VMIN, vmax=VMAX),
but from the doc this isn't clear at least. If it doesn't work, we
have to work out

Dear John,
thank you for your suggestion. Unfortunately, I have just tried that and I
am positive that it does not work.
It works only if the option frameon of the figure is True, which is not
what I want in this case (I have to produce a pdf

Agreed. The only thing I can think of is that the second figure is
reusing the first. You can try calling plt.figure() at the beginning
of the functions to create a new figure, or call plt.figure() in
between the calls to
