This sounds reasonable to me, but I have never seen a plot with that scale and don’t really understand it from your description. Seeing the code usually clarifies things.

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

@Pierre: Yeah, my code looks 99% the same like yours. I'll make a PR
starting from a mix of both - probably closer to yours than to mine 
@Jens: symlog extends to infinity, logit has a compact range, that's why
it's not exactly the same.
Ok I'll make a pull request. Shall I start with a test that fails, then
add the function and show it succeeds? or shall I start directly with
the code and add a test later on?
Cheers,
Fabio
