Wrong argument documentation for reindex_axis

[dargueta]

Problem description

The documentation for DataFrame.reindex_axis() has incorrect documentation for the arguments. The function signature is correct, but the description of fill_value is missing and there's a description of a tolerance argument that isn't accepted by the actual method. This can cause crashes or bad data due to incorrect use of the method.

Expected Output

Documentation for the tolerance argument should be removed, and a description of the fill_value argument should be added.

Hi, I can take care of this if no one else is working on it.

Hm, just a clarification. I don't see a fill_na argument, but there is fill_value which doesn't have a description. Is that the argument you meant?

I'm looking here.

[dargueta]

Agh yeah that's what I meant. Nice catch! I've updated the original report.

Please take a look. I am not very savvy with github so pls let me know if I should do anything differently.
