Hi,
I built and installed the latest matplotlib from SVN.
When I type:
from pylab import *
plot([1,2,3])
I get:
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.4/site-packages/matplotlib/pylab.py", line
2027, in plot
ret = gca().plot(*args, **kwargs)

2131, in plot self.autoscale_view(scalex=scalex, scaley=scaley)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line

self.set_xlim(XL)
File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line
1227, in set_xlim
self.viewLim.intervalx().set_bounds(xmin, xmax)
TypeError: only length-1 arrays can be converted to Python scalars.
I'm using Numeric as numerix. I'm on a Ubuntu box with python 2.4.
Did you try deleting your old mpl directory from site-packages, remove the
build directory from you mpl sources, and rebuild from scratch?

Unfortunately, I forgot to do it 
Then, just after sending the message to the list, it sprang to my
mind. To make it worse, I then mistakenly entered:
rm -Rf /path/to/site-packages
no matplotlib at the end, and hit enter.
There goes my beautiful Python install. 
Is there some switch to setup.py to make it remove the mpl dir or does
one allways have to do it by hand?
Cheers,

I'm posting this because of the other thread Darren started.
I managed to reinstall python (and the modules I use) several days ago
and tried again to run matplotlib with Numeric as the default backend,
but got the same error (the same error Darren is getting). Then I
installed numpy, and everything was fixed 
Best,
Edin

This is fixed now in SVN. The problem was that Numeric arrays lack a "len" attribute, and "hasattr(xmin, 'len')" was being used to find out whether xmin is a scalar or a length-2 array (xmin, xmax). The solution is to do the test with "iterable(xmin)" instead. The bug was introduced in 2782.

Thanks for clearing this up. Coding with three different numeric
libraries in mind certainly is tricky...
