matplotlib-users Mailing List for matplotlib

The mingw/2.4 build still works. There are instructions at the top of
the setupext.py file. The dll linking error you are getting is
something we ran into a lot. If you have numpy installed distutils
will use the numpy\distutils\mingw32ccompiler.py file. In the
Mingw32CCompiler class remove all links to "msvcr71". In my version
of numpy just comment out the whole if block at line 127.

This error used to come up with mingw and python2.4 builds, but now we
use Visual Studio for python2.4. I am surprised no one else has
reported this error though? I see you used the egg binary? Has
anyone else use the python2.4 windows egg with success.

You want to use matplotlib.numerix and use a masked array

More information on this bug: on my WinXP laptop, it seems to only 
manifest under some circumstances. When running the script from inside 
SciTE or ipython, it seems more or less repeatable (sometimes it won't 
show on the first run but does from then on), but if the .py file is run 
directly from the windows explorer, it doesn't show up. On my win98 
desktop, however, it shows up regardless.

I also see this behavior in the qtagg and qt4agg backends.

I see weird behaviour like this in Windows too. In my case, the 
horizontal size of the plot window increases as the pointer is moved 
inside a plot region. i.e. the aspect ratio of the window changes 
erratically, I think between two sizes. Sometimes it remains at the 
incorrect shape when the mouse pointer is shifted outside the plot area 
and sometimes it pops back to the correct shape. Is this the behaviour 
you see? I don't know how to avoid it. I noticed that shifting the 
pointer out of the plot area by moving through the bottom of the window 
seems to avoid the possibility of the window remaining with the 
incorrect aspect. I seem to remember seeing this behaviour on an old 
version of matplotlib. I thought it disappeared and has perhaps 
returned. My memory is hazy on this.
