Whoa.  Can Objective-C programs access classes written in Java?  Do we
have any like that now?

I think I got it.  The grapher class would expect the class offering the
data would have:

 public double getOutputData (int x)

x tells the passer which data stream to provide.  A grapher like a
scatterplot would have to accept 2 data streams.

THis all presupposes I prepare java class objects from scratch, not
using ptplot, because of licensing, correct?
