I use logarithmic bins myself quite often, and the fact that a
logarithmic bin
size is the same as a constant bin size in log space, makes it is easy
to use histogram to get that. Less regulars binning don't work with
histogram, but nobody stops you from writing your own version to work
with them (it will not be as fast as histogram though).
