John,
Attached is a script illustrating how to make contourf plots with a log
colorscale. I made some improvements in svn, as noted in the script,
but you can still do it with the regular mpl release. All of this
should carry through to basemap with no changes in basemap.

John,
We actually have the facility for using a log color scale directly,
including handling out-of-range values, but I confess I am having a
little trouble with it. I can't pursue it right now, but probably can
do so this evening. It looks like the problem is a bug, but I am not sure.

Well, it seems like I'm making progress, but it's stll not the plot I'm

Jeff,
Thanks for the quick reply, below is my plotting code. Here are the answers
to your question about my arrray:
>>> type(Zdat); type(zdat)
>>> shape(Zdat); shape(zdat)
(180, 360)
(596, 596)
>>> shape(lons); shape(x)
(360,)
(596, 596)
>>> shape(lats); shape(y)
(180,)
(596, 596)
I would like

Hi,
Some colleagues have sent some plots which they generated using IDL
(boo!!! hiss!! :D), and they look quite dissimilar to my matplotlib
ones. I would like to mimic their layout as much as possible, which so
far is a success. The only problem is that I don't know what font to
use. In IDL, I beli
Can anyone explain this??

In this case, Zdat is my original array sent to my plotting function. It
seems to lose all it's data when I r

If I'm right, this is because in matplotlib/__init__.py:

That is one solution, but perhaps I should have asked about a solution for
contourf as well. It would be preferable to be able to use a logarithmic
colormap rather than translating the variable.

Hello -
I got confused about specifying colors and linewidths for LineCollections.
I think it would be helpful if the docstrings explicitly state that they
should be sequences.
I know, they do in some way, but it i
