Joe, Henry and others
the modified figure.m for OS X _should_ work if you set the default 
gnuplot term to aqua.

You can do that by setting the environment variable GNUTERM to aqua
"setenv GNUTERM aqua" or "export GNUTERM=aqua" depending on shell.

That was the only way I could think of to implement the feature and 
still give the user a choice of aquaterm or x11.
Not documenting it was very stupid indeed.

Until someone comes up with a better solution, the following doc text 
would probably help:

  - Function File:  figure (N)
      Set the current plot window to plot window N.  This function
      currently requires aquaterm or X11 and a version of gnuplot that 
supports
      multiple frames.
	To use aquaterm, set environment variable GNUTERM to aqua,
	making it the default gnuplot terminal.
