To compile GNUPLOT 2.02 (I got mine from duke.cs.duke.edu) on the NeXT, copy
makefile.unx to Makefile, and make the following changes:

1. lines 6, 8, 11 of Makefile: optionally change destination directories.
2. line 28 of Makefile: change "gamma" to "lgamma" (modern name on NeXT).
3. line 28 of Makefile: delete "#-gx #" (enable optimization).
4. line 28 of Makefile: add " -bsd" (strict BSD compilation).
5. line 34 of Makefile: delete "-lplot" (no plot support on NeXT).
6. line 34 of Makefile: add " -object -s" (smaller object file).
6. line 44 of Makefile: delete "-DUNIXPLOT" (no plot support on NeXT).
7. Line 102 of plot.h: change "HUGE" to "1e308" (only on version 2.0 of the
   NeXT operating system--this is fixed in 2.1).

Then do a "make install", possibly as root if installing in public
directories.

Then you can use the terminal types postscript, psbig, epsf1, and epsf2
for producing PostScript pages or Encapsulated PostScript plots.  I have
also added some types of my own by adding to the files term/post.trm and
term.c to provide for different fonts.  For example, you can add the type
epsf3 by adding:

    ,{"epsf3", "Encapsulated Postscript graphics language, Times font, 11pt",
	   PS_XMAX, PS_YMAX, PS_VCHAR2, PS_HCHAR2, 
	   PS_VTIC, PS_HTIC, EPSF3_init, EPSF_reset, 
	   EPSF_text, null_scale, EPSF_graphics, PS_move, PS_vector, 
	   PS_linetype, PS_put_text, PS_text_angle, 
	   PS_justify_text, PS_point, do_arrow}

to term.c after line 788 (which is just the definition for epsf2 with the 2's
changed to 3's and a different description), and adding:

EPSF3_init()
{
	ps_big = TRUE;
	ps_font = "Times-Roman";
}

to term/post.trm after line 131 (which is just EPSF2_init() modfied).

As a test, give the follwing commands to gnuplot:

     set terminal epsf3
     set output "sinc.eps"
     plot [-20:20] sin(x)/x
     quit

and then do "open sinc.eps" to see the plot in Preview.
