Force bins with zero-height in matplotlib bar plot

matplotlib, python

Solution

Found another solution that may be working more reliably than `set_xlim`:

import pylab
counts = [0,0,0,125,56,0,0,0,34,77,123,0,0,0]
# add a epsilon to counts to force bins to be plotted
epsilon = 1e-7
counts = [x+epsilon for x in counts]
pylab.bar(*zip(*enumerate(counts)), align='center')
pylab.show()

Problem

Consider the following script: ``` import pylab counts = [0,0,0,125,56,0,0,0,34,77,123,0,0,0] pylab.bar(*zip(*enumerate(counts)), align='center') pylab.show() ``` When I run this I get the following image. As you can see the 0-height bins at the edges of the plot are not plotted. However, I want them indeed to be plotted. What can I do to achieve this? I know that I can set the x_lim of the axes (`Axes.set_xlim`). If no other option exists, what approach takes most elegantly into account the width of the bars?
