Sketchy, imprecise plotting theme for matplotlib.

Sometimes you want to illustrate a point and do not want to emphasize on accuracy but on overall relations. This code originated at jakevdp's blog.

Just take the logarithm before calling the plotting functions, i.e. give matplotlib the base-10 logarithms of the values. Then set the tick labels with the true values:

ax.set_xticks([-3, -2, -1], ['1e-3', '1e-2', '1e-1'])

Sometimes XKCDify also does not appreciate large/negative values. You can solve this by transformations into a space it likes.
