Hi,
I installed matplotlib-0.99.3-py2.6-macosx10.6.dmg on MacOS X 10.6.3, python 2.6.5. But I get an error when running the histogram example from
http://matplotlib.sourceforge.net/examples/api/histogram_demo.html
Exception in Tkinter callback
Traceback (most recent call last):

TclError
Would anybody know what's wrong?
Thanks,
Hana

Have you compiled Python yourself? I'm asking because Python 2.6.5
from Python.org is maybe linked against another Tcl/Tk than it links
to when you compile yourself. (I guess the matplotlib._tkagg module
does some patchy things.)

I installed python-2.6.5-macosx10.3-2010-03-24.dmg from python.org. (Sorry, I should have mentioned that before.)

Hmm, could you please run:
otool -L /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/_tkinter.so
otool -L /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/matplotlib/backends/_tkagg.so
and post the output (copy to clipboard with | pbcopy)

# otool -L /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/_tkinter.so
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/_tkinter.so:
/Library/Frameworks/Tcl.framework/Versions/8.4/Tcl (compatibility version 8.4.0, current version 8.4.19)
/Library/Frameworks/Tk.framework/Versions/8.4/Tk (compatibility version 8.4.0, current version 8.4.19)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.3.10)
I needed to modify the path in the second command, since matplotlib was installed into /Library/Python/2.6/site-packages. Could that be the issue? Anyway, here is the output:
# otool -L /Library/Python/2.6/site-packages/matplotlib/backends/_tkagg.so
/Library/Python/2.6/site-packages/matplotlib/backends/_tkagg.so:
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.3)
/System/Library/Frameworks/Tcl.framework/Versions/8.5/Tcl (compatibility version 8.5.0, current version 8.5.7)
/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk (compatibility version 8.5.0, current version 8.5.7)
I see there are some compatibility issues. What would be the best way to deal with it?
Thanks,
Hana

Many apologises for the slow response ...
I'm quite convinced the path is not an issue.

This should be the issue. I think usually the matplotlib binaries are
linked against the same libraries as the Python binaries to avoid such
trouble, but for the 10.6 issue this went wrong somehow? I don't
know.
A possibility would be to compile Python and matplotlib yourself.
This can, for matplotlib, be somewhat troublesome. There is a
recommended way via the make.osx script, and "my" way via tweaking of
the config files. The recommended way downloads freetype2 etc. into a
local directory and does afaik hard linking, "my" way links it the
usual dynamic way against system-wide installed libraries. The
make.osx way is way from perfect, but it should work, albeit I
personally like the other way much more, since it appears much more
clean to me. Tell me what you prefer. If you prefer "my" way, I will
give you detailed instructions, with the make.osx way I'm neither
comfortable nor acquainted, maybe John can help you then. There's
also a recent thread about building matplotlib on Mac (10.6 if I'm not
mistaken) with make.osx.
