Ah, I see.
Well, at least the screen shots from
  http://vofce.sourceforge.net/
look promising. Although I lived well with GnuPlot for this purpose
until now.

There are a few general purpose CAS written in Java available.
(yacas et al, plunder sourceforge as usual). I'm not sure whether
any of them has a plotting component. I'd still be very surprised
if there isn't even an attempt at a java graph plotter on
sourceforge.
If not, ripping code off GnuPlot and/or GNU plotutils should be
easy enough. :-)

You might also ask here (not OSS)

or a dozen or so of other websites
(making plotting applets must be *really* fun!)
