ZeroDivisionError in scale_range

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 “”, 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?

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.

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