[matplotlib-devel] logit scale for frequencies

[Fabio Z. <fab...@tu...>]

Dear all,

I've been using matplotlib with great satisfaction for a few years, but
one feature I've been missing is a "logit" scale. This is essentially a
nonlinear scale that is log both towards 0+ and log towards 1-. It is
useful when one has frequencies in a population (i.e. floats between 0
and 1) and both rare events and very common ones are interesting.

For instance, say you ask about the fraction of people with blue eyes in
various world populations, you want to spot even tiny deviations from
zero or one.

I have coded a scale according to matplotlib's documentation and it
works well, so I was wondering whether you are interested into merging
it into the the main repository. I think it'd be useful because lots of
people have such frequency data, especially now that matplotlib is
becoming popular in the biology/social sciences research communities.

If there is interest, I'll just start a pull request on github and try
to adapt the code to your coding style. It's already PEP8 and similia.

Thanks. Cheers,
Fabio
