OK.  The "print" function is now used to send a plot to a file so replotting is not really needed.  
It would be nice if "replot" and "figure" raised the current or activated plot, but 
that's a personal preference sort of thing I guess.

Not in core Octave.  I don't know the various environment additions to Octave 
("GUI" was a poor choice of words), but this would allow placing a plot in an X 
window that the environment has created rather placing the plot in its own, separate X 
window.  There's a demo in gnuplot's CVS repository.  I've places a screenshot at

under "Gnuplot Stuff", first in the list.
