semilogx and errorbar

On any type of plot where the data on a given axis is strictly
positive, you should be able to set the scale to 'log'. Just make
sure that the axis limits are also strictly positive. Eg

  ax.set_xlim(0.01, 10)

With errorbars, you have to be careful, because if the error limits on
one of your positive datapoints extend into non-positive territory,
you'll get an error with log scaling.
