I was just saying it seems silly to munge on ptplot to get something
worse than what we already have.  Implement new stuff with Swing 
(or a subset that works with Kaffe), and worry about replacing existing
interfaces (e.g. EZGraph, EZBin, Raster), when it is a real problem.

You're confusing interface with implementation.  Nothing prevents you
from putting new Java classes in the analysis package.

The idea is to get rid of this notion of `sides'.

A Selector is a notion foreign to Java; Java doesn't let you 
disassociate messages from classes in a direct way.  Typically, you'd
pass interfaces around, knowing that certain methods would be there
by virtue of the typing.
