matplotlib-users Mailing List for matplotlib

Hi,
Is there an easy way to add axes to a figure, but specify the 'rect' 
in real rather than relative units? For example, something like:
fig.add_axes([0.5,0.5,3.,3.], inches=True)
This would guarantee that for example if I want to increase the canvas 
size to add more subplots, I don't have to re-adjust all the existing 
axes. Also, it makes it easier to figure out the aspect ratio of axes, 
without having to worry about the canvas size. Is there a way to do 
this already, or is the easiest way to write a wrapper for add_axes 
that uses the canvas size from fig?
Cheers,
Thomas

Tim: If that's the case, setting GEOS_DIR=/usr/local and building again 
(after deleting the build directory) should fix it.

Tim: I don't have 10.6 yet, so I've never tried building there. I 
suspect that it's a 32/64 bit library mismatch problem. Since I believe 
OSX builds stuff 64 bit by default on OS X, my guess is you are using a 
32 bit python, perhaps macpython? If so, perhaps building geos with 
CFLAGS="-m32" will fix it. Or, it could be that you have a 64 bit 
python and the lib was built 32 bit.
Maybe someone else with experience with 10.6 will chime in, I'm really 
just shooting in the dark here..

Because that is a very poorly written error message. What is expecting 
is the python.org build, which is installed in /Library/...., not the 
Apple supplied one, installed in /System/Library...., which is likely 
what you have.
I prefer to use python.org's build for various reasons. You might give 
it a try.

It should be fine. It looks like a geoslib other than the one you 
installed in /usr/local is the one being found.

I've been using matplotlib and numpy happily and have gone to install 
basemap.
As part of the basemap 0.99.4 install, I've compiled geos-2.2.3 and 
installed into /usr/local/ - no apparent problems
I then ran >python setup.py install from the basemap directory. No 
issues that I could see.
However, when trying the import I get:
Python 2.6.3 (r263:75184, Oct 2 2009, 07:56:03)
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin

Does basemap build ok on OS X 10.6 or are there some gotcha's I'm not 
aware of?
