[Matplotlib-users] ZeroDivisionError in scale_range

[W Netzberg]

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)

    var = dv/max(abs(vmin), abs(vmax))
ZeroDivisionError: float division

Any ideas?
