I have used add_axes() to do this in the past. E.g., import matplotlib.pyplot as plt fig = plt.figure() leftmarg = 0.125 # change these numbers to taste botmmarg = 0.125 width = 0.825 height = 0.825 frac = 2./3. ax0 = fig.add_axes([leftmarg, botmmarg, width, frac*height]) ax1 = fig.add_axes([leftmarg, botmmarg+frac*height, width, (1-frac) *height]) ax1.xaxis.set_ticklabels([]) plt.show() Sorry it is in object-oriented style instead of pylab style...

Re: [Matplotlib-users] building on MAC snow leopard
This doesn't solve the original problem and I know I worked out a way to do it before my hard disk messed up! But it seems you can get a version going through macports... sudo port install py26-matplotlib sudo port install python_select sudo python_select python26 then edit your .matplotlib/matplotlibrc file (make one if you don't have it). And put backend: macosx into it. Should work fine. Does for me. Now I don't know how one would set python up so it doesn't find my other version, other than moving paths around. Or setting it up so easy_install using the /opt/ version of python.

That's not the problem, as that's the version of Python I have. The problem is that the installer doesn't recognize that Python is installed and hence won't let matplotlib be installed at all. -- R.

[Matplotlib-users] problem with RectangleSelector
Hello list,
I'm encountering a strange problem with the RectangleSelector using the latest
version of svn. Namely it doesn't work if it wasn't initialized as
RS = RectangleSelector(...)
but using
RectangleSelector(...)
in my script.
I modified the example rectangle_selector.py from the folder examples/widgets
to illustrate my observation.
Can anybody reproduce my findings or even explain what is going on?
Thanks in advance for any comments.
Kind regards,
Matthias

[Matplotlib-users] building on MAC snow leopard
Hi,
So I have successfully built a 64bit version of Numpy, Scipy from svn and am
using python version 2.6.5. However in trying to follow the instructions on
this blog (http://blog.hyperjeff.net/?p=160), namely...
changing the make.osx file to
MACOSX_DEPLOYMENT_TARGET=10.6
PREFIX=/usr/local
## You shouldn't need to configure past this point (and yet…)
PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
CFLAGS="-arch i386 -arch x86_64 -I${PREFIX}/include
-I${PREFIX}/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.6.sdk"
LDFLAGS="-arch i386 -arch x86_64 -L${PREFIX}/lib
-syslibroot,/Developer/SDKs/MacOSX10.6.sdk"
FFLAGS="-arch i386 -arch x86_64"
and uncommenting wxagg = False from the setup.cfg
I still seem to run into trouble.
Command I am running is sudo make -f make.osx fetch deps mpl_build
mpl_install
which runs into trouble to do with the libpng lib...
x libpng-1.2.39/scripts/makefile.ne12bsd
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for a thread-safe mkdir -p... ./install-sh -c -d
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
checking whether to enable maintainer-specific portions of Makefiles... no
checking for gcc... gcc
checking for C compiler default output file name...
configure: error: in
`/Users/mdekauwe/src/packages/matplotlib_svn/libpng-1.2.39':
configure: error: C compiler cannot create executables
See `config.log' for more details.
make: *** [png] Error 77
I had a look at the config.log file in the libpng directory and the main
thing I can see is...
configure:3266: checking for C compiler default output file name
configure:3288: gcc -arch i386 -arch x86_64 -I/usr/local/include
-I/usr/local/include/freetype2 -isysroot /Developer/SDKs/MacOSX10.6.sdk
-arch i386 -arch x86_64 -L/usr/local/lib
-syslibroot,/Developer/SDKs/MacOSX10.6.sdk conftest.c >&5
gcc: unrecognized option '-syslibroot,/Developer/SDKs/MacOSX10.6.sdk'
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
cc1: error: unrecognized command line option "-arch"
Not sure what the issue with the arch flag is?
Would really appreciate some thoughts on this, many thanks
Martin

Re: [Matplotlib-users] displaying multiple images in series
Hi Daniel, show should be called only once in a script (see also: http://matplotlib.sourceforge.net/faq/howto_faq.html?highlight=show#use-show) and it starts the mainloop, in which the user may interact with the plot using for instance button or key press events like in my second example. Whenever a key-press-event is recognized the function "event_fct" is called with the corresponding key-press-event as argument. This key-press-event holds information like which key was used etc.. All the possible interaction you can have with the plot in this case happens after the plt.show in the "mainloop", where matplotlib waits for events to happen and calls the corresponding functions, which were "connect"ed to the event. You will find more information about the event handling in the documentation of matplotlib (e.g. http://matplotlib.sourceforge.net/users/event_handling.html#event-handling- tutorial or the examples at http://matplotlib.sourceforge.net/examples/event_handling/index.html). In my first example the trick is done by the function "waitforbuttonpress" and all the interaction happens before the show-command. Because I'm not so familiar with this function, I suggest you again to use the documentation and the examples to learn more about this functionality.
