[Matplotlib-users] Numpy & Numarray
I recently installed Matplotlib .90 under CentOS 5 (like RHEL 5). When I import pylab, it wants numarray rather than the numpy I have installed. Do you need both or is there a config file that needs editing?

[Matplotlib-users] wxPython-2.8 problems
Hi,
I am having problems installing matplotlib-0.90.0 under Mac OS X
(using MacPorts) when having wxPython-2.8.4.0 installed, getting the
following error at build-time:
DEBUG: Assembled command: 'cd "/opt/local/var/db/dports/build/
_Users_jochen_source_macports-trunk_dports_python_py-matplotlib/work/
matplotlib-0.90.0" && /opt/local/bin/python2.4 setup.py build'
setup.py:267: DeprecationWarning: The wxPython compatibility package
is no longer automatically generated or actively maintained. Please
switch to the wx package as soon as possible.
import wxPython

WXAgg's accelerator requires wxPython
running build
Nevertheless, matplotlib builds, but bails out with

Again, a release number mismatch;
but then there is also the
import _locale
error.
With respect to matplotlib I have now resorted to install it with
GTKAGG, which works as expected.
For wxPython: I get the same error when trying to import wxpython or
wx directly in a fresh python:

Is this a known issue?
Is there an easy way around ?
Is there any other information I should send?
Greetings,
Jochen

Re: [Matplotlib-users] problem with saving eps and ps with GTKAgg backend (and current head of SVN)
hi there, out of idea I decided to download gsview and try to open my eps file with it. It still showed it truncated but this time gsview has resizing capabilities, and I could actually reformat the plot so that it shows the whole figure and then save it. Given the fact that Matthew could not reproduce my issue and noticed that the ps figure was looking slightly different, I have the feeling that somehow ghostscript is not behaving correctly on my system, though I have no clue why or how. Is anyone expert in these matters around? thanks a lot, Johann Matthew Auger wrote: > I was having the same problem, but the recent xpdf thread pointed me > to a/the solution.
