That problem was fixed quite a few months ago; I don't recall exactly when.

Thanks for your responses, David and Bill.

I'm quite busy at the moment to go into detail in this, but strangely enough 
when I changed the backend from the default (GTK(Agg?) - I'm on linux) to 
QtAgg the bug disappeared.

I think too that there could be an issue with numpy, so I just recompiled the 
whole python-numpy-mpl toolchain using the latest versions of everything 
available. I'll test ASAP if the problem under GTK persists, and then I'll 
report here.

Thanks again,

  Francesco

Works fine here.

pylab.matplotlib.__version__
'0.87.5'

pylab.matplotlib.__revision__
'$Revision: 2761 $'

Which version are you using?

Random number generation is the art of producing pure gibberish as 
quickly as possible.

The following code throws ZeroDivisionError:
import numpy, pylab
z = numpy.random.normal(-0.37727, 0.1, size=10)
pylab.plot(z)
pylab.show ()
The stack trace:
Traceback (most recent call last):
  File "<stdin>", line 3, in ?
  File "/usr/lib/python2.4/site-packages/matplotlib/pylab.py", line 2018, in
plot
    ret =  gca().plot(*args, **kwargs)
  File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 2790, in
plot
    self.autoscale_view()
  File "/usr/lib/python2.4/site-packages/matplotlib/axes.py", line 817, in
autoscale_view
    self.set_ylim(locator.autoscale())
  File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line 798, in
autoscale
    return take(self.bin_boundaries(dmin, dmax), [0,-1])
  File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line 768, in
bin_boundaries
    scale, offset = scale_range(vmin, vmax, nbins)
  File "/usr/lib/python2.4/site-packages/matplotlib/ticker.py", line 733, in
scale_range
    var = dv/max(abs(vmin), abs(vmax))
ZeroDivisionError: float division

Any ideas?
