I think may hist function have some problems, at certain cases when I plot an histogram with matplotlib:
pylab.figure()
H, bins, _ = pylab.hist([2,2])
print H
print bins
The result is:
[ 0. 0. 0. 0. 0. 2. 0. 0. 0. 0.]
[ 1.5 1.6 1.7 1.8 1.9 2. 2.1 2.2 2.3 2.4 2.5]
Do you see at the plot that "bump" at between 1.5 and 1.6, where it is coming from? How can I avoid it?
