the first column has a value much higher than 1.0, it's not a
> probability distribution I believe.
Ahh, this appears to be a docstring bug. The plotting function
matplotlib.axes.Axes.hist docstring indicates "probability
distribution" but the underlying function matplotlib.mlab.hist which
computes the histogram correctly states that it returns a probability
*density*, ie, it integrates to one.
Thanks for pointing this out. The docstring will be updated for the
next release.
