Log scale on bar chart hides bars

[gjx]

When I try use log scales on a bar plot in pandas, the area of the bar disappears. Example in this ipynb

I think the answer is to pass log=True to bar, as in this SO answer, but when I add log=True as a kwarg to Series.plot(), it doesn't fix the problem.

This should be fixed in git master now, can you try it out? (d82e5aa)
