I've been having trouble gettin histograms to work on arrays.  This is no=
t
the particular case that I've had, but illustrates the general error.=20
Wondering if anyone knew what I was doing wrong?  Thanks.


>>> from pylab import *
>>> from numpy import *
>>> x=3Dones([2,10])
>>> x
array([[1, 1, 1, 1, 1, 1, 1, 1, 1, 1],
       [1, 1, 1, 1, 1, 1, 1, 1, 1, 1]])
>>> hist(x[0])
