normplot and cdfplot

I have been using matplotlib as a replacement for MatLab and have had
a great deal of success repicating basic plots. I was now trying to
replicate some of the more value added functionality like the normplot
and cdfplot. The normplot is particularly tricky because you need to
scale the axises by the inverse normal cdf. There seems to be
functionality to write scalers but the only ones that come with
matplotlib out of the box are linear and log.

Does anyone know how I might be able to achieve this functionality?
