Thanks Chris!  I'm using ipython -- why suffer with anything else;-) -- and
I use tab completion to see namespace properties.  I have it set to filter
out double-underscore names on the assumption that these are intended to be
private by convention.  It seems to me that __version__ should not be
double-underscored unless I misunderstand the convention.  Anyway it works
and I will certainly remember it now.  As soon as i type matplotlib.__v(tab=
)
it shows up.  My version is 0.81 for those who can't handle suspense.

Originally my question was about how to handle line properties when using
psd and other higher-level plotting routines.  I figured out how to set the=
m
manually by keeping a reference to the axis before plotting and then
manually adjusting things one item at a time.  It's wordy but works fine. I
see now there is a setp() function that should help with this but I still
have to get the lines from the axes object first.  Directly setting these
properties in psd would be much cleaner in common use cases I think.

I looked in to how to improve this for psd and csd at least.  It turns out
to be trivial to add. I just added  '**kwargs' to the parameter lists of ps=
d
def and to it's call to plot().  this is in file axes.py.  This way the
extra keywords just get passed along.  I don't know how to submit a patch
but could this be added to psd and csd functions?  I also don't know if
there would be any side effects so it might need to be checked a bit more
carefuly.
