[Matplotlib-users] changing labeling of axes

[Thomas Caswell]

You can do this with the formatter on the axis, see
https://matplotlib.org/gallery/ticks_and_spines/tick-formatters.html#sphx-glr-gallery-ticks-and-spines-tick-formatters-py
 and https://matplotlib.org/api/ticker_api.html

You can also pass log-spaced bins to `hist2D` and then set the axis scales
to log (but trying to construct an example did not got as I expected...)
