I've had a lot of luck with hybrid systems like this.
One win is that once the data is in Java, you
can basically use any of the literally dozens of 
plotting packages available in Java.

Here's a pointer to a paper (presented at LUGM98) which describes
a Lisp/Hybrid system I worked on some time back:

One thing you might consider is the LIJOS system:

   http://www.pointnclick.com/lijos/index.html

This is a Lisp Implementation of the Java Object (and Data)
Streams.  (One advantage here is that, since the streams
speak the pure Java protocol, no modifications are required
to an existing Java system; i.e. as far as the Java system
is concerned this Lisp system on the other end might as well
be another Java system.)

Hope this helps,
Nichael

[P.S. If anyone here as looked at LIJOS before, a couple
of updates:  First the LispObjectOutputStream is completed
and, second, PnC has decided to release the source, hence
portability, etc, is less an issue.]
