Re: [Matplotlib-users] nonlinear axes for imshow
Hi Eric, thanks for the help, but this doesn't do what I want. I don't want to change the image in any way, I just want the axes to have a decreasing spacing. I made a small example with ms paint to clarify. http://www.nabble.com/file/p25867951/axes.png I could do this with ax.set_xticks() and ax.set_xticklabels(), but I was wondering if there is a way that also changes the whole coordinate system and not only the labeling. For example, the position of the mouse pointer will not be shown anymore when I use custom ax.set_xticklabels().

Re: [Matplotlib-users] Little issue with blitting technique
I haven't tested it with qt4, but with gtk, add_axes DOES work. So, can you try other backends and see if they work? And, I believe that add_subplot -> add_axes is a only change you made?

Re: [Matplotlib-users] Little issue with blitting technique
Hello, I've tested so far with wx and QT4 backend. The two are buggy. Easy way to reproduce the bug (another way I mean) ax = p.subplot(212) ax2 = p.subplot(211) and the two backends got the same error. Note that I'm under windows. I'll try under linux tonight just to check. I'll also try gtk backend as you suggest.

[Matplotlib-users] Installing matplotlib on mac os 10.6 (Snow Leopard)?
I've not been able to find a successful way to install matplotlib since upgrading to OS 10.6. There doesn't seem to be an egg for it. Easy_install matplotlib finds an old version (0.91) that is not compatible with the new numpy supplied by Apple. Easy_install matplotlib-0.99.1 can't find it. Likewise, easy_install http://sourceforge.net/projects/matplotlib/matplotlib-0.99.1/matplotlib-0.99 .1.1.tar.gz doesn't find it. I tried downloading the gzipped tar file, then python setup install , but I got a compile error. I'm now stumped. Any ideas? Thanks, Bill Carithers -- Come build with us!

Re: [Matplotlib-users] Little issue with blitting technique
I've just installer GTK on windows + tested your file and it works... Moreover, I've modified the source to make the code use QT4Agg instead of GTK and the bug does not appears. So I think it is more an issue of misusing bliting technique in other examples. (still your gtk example is more beautiful but 10 times slower than other examples, so is blitting really working in this case ?)

[Matplotlib-users] [Solved] Little issue with blitting technique
Hey, coparing on how GTK2 example is done I've seen a difference between the two! In QT4Agg example and WX example the code use: canvas.copy_from_bbox(ax.bbox) replacing all occurrence of ax.bbox with ax.get_figure().bbox solved all the issue I add. Perhaps we should correct the examples. I can send you the good working example if you want.

Jeff,
I had already had tk-dev installed:
$ sudo apt-get install tk-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
tk-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded
Please see my latest... This is amazingly difficult. Didn't remember it being
this hard when I did it on my Suse machine.

Re: [Matplotlib-users] cannot install kubuntu 9.04 mpl 0.99.1.1, python 2.6
Well, while I waited for more help/thoughts on the matter, I happened to have another machine with Jaunty 9.04 that I thought I'd give a try I consolidated the install down with the "apt-get" commands at the bottom, and matplotlib failed on the new machine as well (but took longer to fail possibly because the other machine had already compiled everything up to the failing point). This "new" machine is Intel-based, whereas the other one was AMD-based. Similar error message: [code] In file included from /usr/include/c++/4.3/ext/hash_map:64, from ./CXX/Extensions.hxx:68, from src/_backend_agg.h:8, from src/_tkagg.cpp:18: /usr/include/c++/4.3/backward/backward_warning.h:33:2: warning: #warning This file includes at least one deprecated or antiquated header which may be removed without further notice at a future date.

[Matplotlib-users] help with fill_between and a colorbar
Hello, I have the following function as an example. You can see I started to
play with one of the demos to put a colorbar on it. I'm a little confused
how to make this work, as on my figure I have several 'collections'. The
other examples I have seen deal with one collection. Maybe someone could
show how to make a color bar here??
Thanks!
