I identify the problem.
There is no basemap data directory and the app search those datas in
[MY_DIR]\dist\library.zip\mpl_toolkits\basemap\data
But I don't know how to add it at the compilation....

it looks like you've got GTK set as your default back-end, but are not 
running and X-server on this box.
If you want to use MPL without a GUI, you need to set your default 
backend to "AGG", but you probably shouldn't use pylab for that anyway, 
but rather use the OO API -- some googling will tell you about that.

It looks like you're using the gtk backend but you're running on a 
remote terminal without an X11 connection. That's what "could not open 
display" probably means. Are you logged in remotely by any chance? Does 
'python -c "import gtk" ' work?
If you want to run headless, you can use the "Agg" backend. See here:

I'm not shure whether the following suggestion solves your problem,
but it would simplify your script anyway.
import matplotlib
...
setup(..., data_files = matplotlib.get_py2exe_datafiles())
And maybe don't forget to exclude 'libgdk_pixbuf-2.0-0.dll' (on my
system) in 'dll_excludes'. But I actually don't remember for what
reason I had to exclude it.
hth,
Friedrich

I did spend a couple of hours looking at the code, and there are a few 
places where the child components do depend on data/methods in the parent 
container, even though the "child" objects can be created without the 
parent; I'm about 80% sure that there are no guards against calling those 
child methods without a parent, so it seems safer to rework my model to 
use the top-down approach.
Perhaps I'll find some time soon to learn enough to create some unit tests that 
confirm/refute the above, and if true I'll file some bugs. 

Hello World,
I'm using py2exe to create an executable on windows .
There is a setup.py file that allows me to create this executable under eclipse.
I have a problem with basemap.
Probably, the app needs data basemap directory but I don't know where to put it.
Thanks for your help.

Hello,
I am testing the newly added subplots function in ipython -pylab with the
following code:
f, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2,2, sharey=True)
ax1.plot(np.random.random(20))
ax2.plot(np.random.random(20))
ax3.plot(np.random.random(20))
ax4.plot(np.random.random(20))
For some reason scaling the y-axes logaritmically works only on the focused
figure canvas, the rest of the subplots are scaled in a distorted fashion.
Axes labels change to proper notation but the scaling stays as if linear
along with the data. See for better description:
http://img408.imageshack.us/img408/7149/logscale.png
Any ideas?

Actually, it does not draw the polygon edges, but leaves small gaps 
between them. Through those gaps you can see the background. (This also 
happens with polar plots and other polygons by the way.) I consider this 
a bug, though there are ways around it. For contour plots one can plot 
two contourplots over each other, one with different levels (or a 
different number of levels) than the other. Messy, but it works.

Well, to be clear.
How to get tick labels at the very end of the axes?
If the x-axis goes from is 0, 1 the axis ticks will be at 0.2,0.4,0.6 and
0.8 as you can here: see
http://matplotlib.sourceforge.net/examples/mplot3d/2dcollections3d_demo.html
How do I additionally get labels at 0 and 1?
Hope this triggers a few responses. :D Thanks in advance.

When I use contourf to plot a filled contour map, I get some white-like lines
between each color patches.
This is not like the contourf doc string says: "it does not draw the
polygon edges.", actually, it does.

The figure above is what I get by contourf, but this is not exactlly what I
want.
The filled contour map I want should be like this one:

Any advices?
Thank you!
