You need to create text instances at the places you want the bar
labels -- something like
from pylab import figure, nx, show
width = 0.5
xs = nx.arange(7)
ys = nx.mlab.randn(7)+5
fig = figure()
ax = fig.add_subplot(111)
ax.bar(xs, ys, width=width)
for x,y in zip(xs, ys):
ax.text(x+width/2., y, '%1.1f'%y, va='bottom', ha='center')
show()
