In pylab: just choose the number of bins. Hope this helps.

If you know your data are integers, you might get nicer results by
specifying the bins rather than autogenerating them by passing in
number of bins. Eg for a 12 sided dice
import matplotlib.numerix as nx
bins = nx.arange(1,13)
n,bins,patches = P.hist(throws, bins)
