Mark,

   I went off in the wrong direction with this function from the start, and I
need to re-write it using list comprehension.

   What I need to do is cycle through different items in the tuples in a
nested fashion. That is:

   For each level-1 name in the list of tuples:
     For each level-2 name in each level-1 name:
       For each level-3 name in each level-2 name:
 	For each level-4 name in each level-3 name3:
 	  Call the appropriate plotting function based on curve shape.

   At my level of python experience this is proving to be a major challenge
that has taken my attention for well too much time. For those of you with
more experience the algorithm implementation is probably simple and obvious.
