I think the problem might be related to using numarray and not numpy.
matplotlib is not heavily tested (if at all) on anything but numpy anymore.
See this from your output log:
D:\Program
Files\Python-2.5.1\Lib\site-packages\matplotlib\numerix\__init__.py:65:
DeprecationWarning: numarray use as a numerix backed for matplotlib is
deprecated
DeprecationWarning, stacklevel=1)
Indeed, using float as a type specifier works with numpy but not with
numarray.
Try setting your numerix setting to numpy in your matplotlibrc file.
If there are good reasons that you need to keep using numarray (for
compatibility with your own code for instance), please mention that on
this list -- there may be workarounds.
Cheers,
Mike

Hello i' am an newbie in matplotlib and python!
I've installed python 2.5.1 + numpy 1.0.4 + numarray 1.5.2 but have many
problems !
I've written an easy plot script
import matplotlib
import pylab
from pylab import arange,sin,pi,plot,xlabel,ylabel,title,grid,show,axis
ymax = max([1,4,9,16,12,5,7,13,7,1,33])
ymin = min([1,-4,9,16,12,5,7,13,7,1,33])
print 'ymax = %s' % ymax
print 'ymin = %s' % ymin
plot([1,2,3,4,5,6,7,8,9,10,11], [1,4,9,16,12,5,7,13,7,1,33], 'ro')
axis([0, 15, ymin-5, ymax+5])
xlabel('time (s)')
ylabel('voltage (mV)')
title('About as simple as it gets, folks')
grid(True)
show()
-- AND i get some problems
