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.
