Sorry, I should have explicitly stated most of this: This is on Redhat 9.0. I built numarray and matplotlib myself. Initially the matplotlib build had problems finding the numarray headers since I have to install everything to a non-standard place (I don't have root) and simply modifying basedir in setupext.py did not work. I made some sym-links and added to an include_dir to fix that and now there are no build problems. My .matplotlibrc is identical to the one put in share/matplotlib except numerix is set to 'numarray' and set datapath to '/local/share/matplotlib' which is where all the fonts and stuff are. Thanks again, Scott. -----Original Message----- From: Stephen Walton [mailto:ste...@cs...] Sent: Wednesday, November 17, 2004 12:55 PM To: Zelakiewicz, Scott (Research) Cc: 'mat...@li...'

Still no luck. I am not trying to run this interactively. Switching
between TkAgg and GTKAgg does not seem to do anything.
Here is the output from `python simple_plot.py --verbose-helpful`
Thanks again,
Scott.

To test your installation, cd into the examples dir and try running
simple_plot.py from the unix shell.
> cd examples
> python simple_plot.py
OR you can choose your backend from the shell with
> python simple_plot.py -dTkAgg
> python simple_plot.py -dGTKAgg
If that works, almost surely you have an interactive problem that will
be cleared up with the links above. If now, rerun the script with
--verbose-helpful and report back.
Good luck,
JDH

Did you try rm -rf your old site-packages/matplotlib and your build
subdirectory of the matplotlib src tree, and rebuild/install
matplotlib cleanly?
If that fails, it might be instructive to edit
"/local/lib/python2.2/site-packages/matplotlib/lines.py", line 234,
and print len(x), len(y) and seeing what the hell is going on, since
the last error is
if midPoint and self.gridOn: self.gridline.draw(renderer)
File "/local/lib/python2.2/site-packages/matplotlib/lines.py", line 234,
in draw
xt, yt = self._transform.numerix_x_y(x, y)
ValueError: x and y must be equal length sequences
Finally, I can see that this is an error arising from drawing the
grid. Does it go away if you turn the grid off (axes.grid : False in
rc and comment out the grid call in simple_plot).
I'm grasping at straws here - my best guess is above, that you have
some incompatible old matplotlib lying around.

First off, thanks to everyone for the replies.
I think the problem turned out to be that when you do a `python setup.py
clean` it does not clean out the build directory (despite what it is
saying). I manually cleaned it out, rebuilt and everything is fine. There
must have been some strangeness left over from when I was trying to resolve
my include_dir issues I mentioned before.
Just for the record, I am having no problems building against numarray 1.1
or 1.1.1. I started to try to use numeric, but it wanted a lib for cblas
that I didn't have. Before I started any of this, I deleted all old
versions of numarray and matplotlib is had in site-packages.
Thanks again for the help,
Scott.

I'm afraid I can't be much help. I long ago updated all my RH9 boxes to FC1 and I also have root access on them.

If you are running interactively from the python shell, you need to make sure "interactive" is set to True in your rc file and do not use show. http://matplotlib.sourceforge.net/faq.html#SHOW Also, to work interactively, you must use either the tkagg backend or a python shell that supports threading for the GUI you are using (GTK or WX) such as ipython http://ipython.scipy.org, which has explicit support for matplotlib in the pylab mode http://matplotlib.sourceforge.net/interactive.html To test your installation, cd into the examples dir and try running simple_plot.py from the unix shell. > cd examples > python simple_plot.py OR you can choose your backend from the shell with > python simple_plot.py -dTkAgg > python simple_plot.py -dGTKAgg If that works, almost surely you have an interactive problem that will be cleared up with the links above.
