How to display the value of the bar on each bar with pyplot.barh()?

Question

I generated a bar plot, how can I display the value of the bar on each bar?

Current plot:

Answer 1

For pandas people :

ax = s.plot(kind='barh') # s is a Series (float) in [0,1]
[ax.text(v, i, '{:.2f}%'.format(100*v)) for i, v in enumerate(s)];

That's it. Alternatively, for those who prefer apply over looping with enumerate:

it = iter(range(len(s)))
s.apply(lambda x: ax.text(x, next(it),'{:.2f}%'.format(100*x)));

Also, ax.patches will give you the bars that you would get with ax.bar(...). In case you want to apply the functions of @SaturnFromTitan or techniques of others.
