In pylab: just choose the number of bins. Hope this helps. Alan Isaac >>> import pylab as P >>> help(P.hist) Help on function hist in module matplotlib.pylab: hist(*args, **kwargs) HIST(x, bins=3D10, normed=3D0, bottom=3D0, orientiation=3D'vertical', *= *kwargs) Compute the histogram of x. bins is either an integer number of bins or a sequence giving the bins. x are the data to be binned. The return values is (n, bins, patches) If normed is true, the first element of the return tuple will be the counts normalized to form a probability distribtion, ie, n/(len(x)*dbin) orientation =3D 'horizontal'  'vertical'. If horizontal, barh will be used and the "bottom" kwarg will be the left. kwargs are used to update the properties of the hist bars Addition kwargs: hold =3D [TrueFalse] overrides default hold state >>>
