Status of polar() / rgrids() / thetagrids() documentation

I'm trying to describe how to plot polar graphs with mpl, but the doc
for the above functions (in pyplot api page) is a bit "reduced".

For example, thetagrids() doc says it receive a fmt karg but calling
with it the error:

AttributeError: Unknown property fmt

is returned.

I'd like to know if there's a better place to have doc about those
functions, or if
there's an effort to improve it already planned.
