You want legend((bar1[0],bar2[0]), ('First','Second')). What happened
was that matplotlib made a legend entry for two of the blue bars in
bar1; it would have made six entries, but stopped because you only gave
it two labels.

I get four points, not two, but perhaps this has changed in the svn
version. At least in the svn version you can control the number of
points with the numpoints keyword argument:
In [6]: plot([3,1,4,1,5,9,2,6,5,3,5],'bo')
Out[6]: [<matplotlib.lines.Line2D instance at 0x16cf9b98>]
In [7]: legend(_, ('foo',), numpoints=1)
Out[7]: <matplotlib.legend.Legend instance at 0x16cf9bc0>
