For some reason, the current cvs build of matplotlib
generates a strange error:
import pylab
pylab.plot([1,2,3])
yields:
ValueError: arrays must have same number of dimensions
I thought perhaps a second array was required, but:
pylab.plot([1,2,3],[1,2,3])
yields the same error.
Anyone else getting this?
Here is a full debug of the call using ipython:
In [4]: pylab.plot([1,2,3])
···
