* This version of the 'unixplot' driver produces device independent
* output. I've chosen parameter values so that the PostScript output
* produced by plot2ps is 5" x 3". You can use the 'set size' command
* to get output up to 8.25" x 8.25", i.e. size values larger than
* 1 are okay.
*/
/*
Unixplot library writes to stdout. A fix was put in place by
..!arizona!naucse!jdc to let set term and set output redirect
stdout. All other terminals write to gpoutfile.
*/
/* This is a device independent format, so the output should look
* look "reasonable" on any output device. I set things up there so
* that the output of plot2ps is 5" x 3" (standard GNUPLOT size).
* You can use GNUPLOT's size command to obtain plots to almost the
* 8.25" x 8.25" limit.
