I think this is because the bar is going from zero to your value, so the
left edge of the rectangle becomes log(0). I see this when using the 'k'
and 'l' keys to interactively put a histogram on a log scale. Passing in
log=True for hist fixes this. I'm sure there's something similar that can
be done for bar/barh.
