Mac backend problems for nearly all backends.

Community matplotlib-users

%^&#!!! My sincere apologies, gmail sent before I was ready. To continue:
GtkCairo: looks great, crashes ipython on resize.

Wx: color issues, not stable.
Qt: installs from fink, but won’t load.

In any case, it’s not the Gtk/Qt/Wx problems that are important, it’s the OSX backend issue. Others whom I work with do not have this issue, but installed using EPD.
Has anyone else experienced such problems?

Thanks for your help; let me know if there’s more info I can provide.

Greetings.

I did quite a bit of digging on this and cannot find similar problems, but if I did miss an earlier discussion, then I apologize.

In any case, I have been having royal problems with GUI backends and matplotlib.

Some background on where I’ve been having these problems:
Machine 1: OSX 10.5.8 G5 PPC
Machine 2: OSX 10.5.7 Macbook pro/Intel
Code versions: python 2.5.4, Numpy 1.3.0, Scipy 0.7.0 (all obtained through fink.)

MPL versions: 99.0.1 and 99.1.1 (Older obtained through fink, newer installed from source.)

Here are the issues; behavior is consistent on both machines:

MacOSX backend: Loads plots quickly, but when I try to save, I cannot type in the file name area of the save file dialog. Furthermore, with ipython, I can continue to use the ipython prompt up until the I shut the plot window. ipython then freezes until I control-c it. This occurs in both versions.

TkAgg backend: In 99.0.1, this works fine. However, it is slow, hence my want for a different working backend. in 99.1.1, the plot window opens but the picture is never drawn. After a moment, segfault back to the x11 prompt. Blerg.

GtkAgg: Bad color (e.g. the background is pink rather than gray, color tables are way goofed up. Writes to file fine.)

MPL versions: 99.0.1 and 99.1.1 (Older obtained through fink, newer installed from source.)
Compilers: gcc/g++ 4.0.1/Mac.

Here are the issues; behavior is consistent on both machines:

the file name area of the save file dialog. Furthermore, with ipython,
I can continue to use the ipython prompt up until the I shut the plot
window. ipython then freezes until I control-c it. This occurs in

window opens but the picture is never drawn. After a moment, segfault

I’ve tried nearly all of the GUI tool kits, but ran into some problem:
GtkAgg: Bad color (e.g. the background is pink rather than gray, color tables are way goofed up. Writes to file fine.)
GtkCairo: looks great, crashes ipython on resize.

Wx: color issues, not stable.
Qt: installs from fink, but won’t load.
Fltk: Couldn’t get it to install via fink; can’t remember why.

In any case, it’s not the Gtk/Qt/Wx problems that are important,
it’s the OSX backend issue. Others whom I work with do not have this
issue, but installed using the EPD.
Has anyone else experienced such problems? Anyone know possible fixes?
Given that this occurs on two different machines with two different MPL versions (a total of 4 combinations), I’m guessing it’s my fault somehow.

Thanks for your help; let me know if there’s more info I can provide.

Are you using a framework install of Python? Also, does the MacOSX backend work with plain python instead of ipython?

I am using the EPD and have have an issue with saving( I cant type in a name for the file) Are you using the 64bit? I don’t think wx runs in 64 bit and so something else is used in the EPD 64 distro. Not really clear on this and has been awhile since I looked at it.
