[Matplotlib-users] Simple plot command fails

[Zelakiewicz, S. (Research) <zel...@cr...>]

Hi,

I am trying to get matplotlib (0.64) up and running.   When I run the
following commands
	from matplotlib.matlab import *
	figure(1)
	plot([1,2,3,4])
	show()
I get an error message (shown below), the figure window draws with the
buttons on the bottom, but no plot is drawn.  I have tried this with the
GTKAgg and TkAgg backends and they both give the same error.  If it matters,
I am using numarray.

Any help/suggestions would be appreciated.

Thanks,
Scott.
