RE: [Matplotlib-users] Simple plot command fails

[Zelakiewicz, S. (Research) <zel...@cr...>]

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.

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.
