I did earlier today; I'm hoping it will go up in the next day or so.
WXAgg is built against wxPython 2.6.x because last I heard the 2.8.x 
issues weren't resolved.

Well that explains why there is no readme in the distribution on 
source forge.
Any chance you will build a distribution of matplotlib 0.90 for 
pythonmac soon?

It's Python 2.5, and the new Matplotlib 0.9 built from source. I saw the 
same problem with Python 2.4.3 and Matplotlib 0.8.(can't remember), 
which was part of the reason I upgraded. However, I didn't look at the 
problem with gdb using the earlier versions.
Thanks,

If I go to the matplotlib download page:
<http://sourceforge.net/project/showfiles.php?group_id=80706>
then there is a table showing "matplotlib" and "matplotlib-toolkits". 
Clicking on "Download" or "matplotlib-0.90.0" results in a page with 
no files.
On the other hand, clicking on "matplotlib" (the upper-left link of 
the table) does the right thing. So does scrolling down, but that may 
be not be obvious unless one has a really big window.

Oops, I just realized how misleading my earlier message was. I do NOT 
build the official matplotlib Mac packages. I have been building the 
packages at pythonmac.org. I started that because an earlier Python 
2.4 matplotlib package crashed when using a user-installed Tcl/Tk* 
and just never got out of the habit.
So I don't have anything to do with the official matplotlib Mac 
binaries and I have no idea what's in their ReadMe files. I *hope* 
they include the necessary info about what version of wxPython is 
required and all that, but I don't know.
I can't help you with easy_install either. Sorry.

* The crash stems from a limitation of the Mac build of Python 2.4 
that was fixed in 2.5. By default MacPython 2.4 does not find a 3rd 
party Tcl/Tk. There's a simple patch to fix this but it appears that 
binary packages that use Tkinter may not work with 3rd party Tcl/Tk 
unless the patch was applied by the person doing the build.

I will try to remember to look there in the future to know which wx 
is supported, thanks.
The matplotlib on sourceforge
http://downloads.sourceforge.net/matplotlib/matplotlib-0.90.0-py2.5- 
macosx-10.4-fat.egg?modtime=1171118530&big_mirror=0
is an egg but doesn't install with easy_install. Complains there is 
no setup.py file.
I copied the .egg directory into ....site-packages but it is not 
automatically included in sys.path
when I run the python interpreter.
I have to manually do this:
 >>> from pkg_resources import require
 >>> require("matplotlib")
[matplotlib 0.90.0 (/Library/Frameworks/Python.framework/Versions/2.5/ 
lib/python2.5/site-packages/matplotlib-0.90.0-py2.5-macosx-10.4- 
fat.egg)]
for it to be accessible.
I guess I have to add it manually to my PYTHONPATH or else generate 
a .pth file and put it in site-packages
to get it automatically added to sys.path?
In the past the distributions were a little more user friendly for 
installing.
I know I can't complain too much since you are doing all the work.
Just wondering if I missed something when I tried to install it.

What version of matplotlib, what version of Python and where did you 
them from from (build from source, some binary installer, fink...?)

It was compiled with wxPython 2.6. It will NOT work with wxPython 2.8.
What Chris is referring to is that when I built matplotlib against 
wxPython 2.8 (in hopes of serving that at pythonmac.org) I ran into 
several problems:
- there appears to be broken code in matplotlib's wx support (making us 
wonder how and why it works with wxPython 2.6 at all)
- fixing that left something that ran but had some odd problems

That information is in the ReadMe file in the installer.
Keep in mind that we have:
- which back ends are supported
- which numeric packages are support
I don't want to try to fit all that into a file name.

Hi all,
Matplotlib occasionally crashes Python at the end of a long program on 
my powerbook g4 running OS X 10.4. gdb output follows:
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x0a68fe40
0x002eae50 in visit_decref (op=0x28a1cb0, data=0x0) at

270 /Users/ronald/Python/r25/Modules/gcmodule.c: No such file or 
directory.
 in /Users/ronald/Python/r25/Modules/gcmodule.c
or
Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000056
0x002eae50 in visit_decref (op=0x28a17e0, data=0x0) at

It's always something like that, and it always happens after the little 
Python icon starts bouncing around in the dock. I don't know anyone 
named Ronald and no such directory exists on my machine.

Where can I find the master TeX document for 0.90? I'd like to make some

Dear Gary, "_ns" is the numpy backend. Do you have numpy installed? Is 
it working? Are you compiling matplotlib from source? What version of 
Ubuntu are you using (Dapper? Edgy?)
