Thread: [Matplotlib-users] Plotting histograms with zero counts

Hi, when I do:

   hist([0,0,0], bins=10, range=(0,10))

How come the single bin takes up the entire plot?  Same with just two 
values, or anything less than 10 - the two bars take up the entire plot, 
no matter what I plug in for range.  I'd just like 10 bins, from 0 to 9.

That's a bug in the current implementation (see also

This is fixed now on the trunk.
