  It's like that now too, I just refactored some of the repeated code into 
different functions, but it's still confusing to work with.  Some of it has 
to change because it (2d plots) just works differently now, but basically I 
think it's working as is.  All that remains is to add in the label mode and 
the rest of the actions.
