PyQt and MatPlotLib - Embedded Bar Chart Starts at Origin

I am trying to reproduce this chart embedded in a PyQt GUI but there is a problem with what my code

N = 5
menMeans = (20, 35, 30, 35, 27)
womenMeans = (25, 32, 34, 20, 25)
menStd = (2, 3, 4, 1, 2)
womenStd = (3, 5, 2, 3, 3)
ind = np.arange(N)    # the x locations for the groups
width = 0.35       # the width of the bars: can also be len(x) sequence

p1 = self.axes.bar(ind, menMeans, width, color='#d62728', yerr=menStd)
p2 = self.axes.bar(ind, womenMeans, width,
         bottom=menMeans, yerr=womenStd)

self.axes.set_ylabel('Scores')
self.axes.set_title('Scores by group and gender')
self.axes.set_xticks(ind)
self.axes.set_xticklabels(['G1', 'G2', 'G3', 'G4', 'G5'])
self.axes.set_yticklabels(np.arange(0, 81, 10))
self.axes.legend((p1[0], p2[0]), ('Men', 'Women'))

produces.

enter image description here

G1 should not be exactly at the origin but a little along. What needs to be changed to do this?

The example you link to is for matplotlib version 2.0. However you are running 1.5 or below. So you need to refer to the example of the previous versions: bar_stacked example for 1.5. Alternatively, you can update matplotlib to version 2.0.

The alternative would be to use the align argument to bar

plt.bar(... , align="center")
