matplotlib allows you to apply generic coordinate transformations to  
the axis.  The readout cursor then applies that same transformation.

On a side note.
It is a very robust plotting package and I believe it hold it own very  
easily with gnuplot.
When I dive down into plotting with it I can get even better results  
with matplotlib than with gnuplot, because I can run python code  
against the graphics that the plots generate.
