hello,
I try to have my hist bars inside grids, some bars creep into others..
I create my hist thus:
bins = nx.arange(1-(0.9/2),max(values))
n, bins, patches = hist(values, width=0.9)
example:

and I have display problems for axis names, I use : xticks(arange(len(names)), names)
if any idea.. thanks
