NAME
     plot: openpl, erase, label, line, circle, arc, move, cont,
     point, linemod, space, closepl - graphics interface

SYNOPSIS
     openpl()

     erase()

     label(s)
     char s[];

     line(x1, y1, x2, y2)

     circle(x, y, r)

     arc(x, y, x0, y0, x1, y1)

     move(x, y)

     cont(x, y)

     point(x, y)

     linemod(s)
     char s[];

     space(x0, y0, x1, y1)

     closepl()

DESCRIPTION
     These subroutines generate graphic output in a relatively
     device-independent manner.  See plot(5) for a description of
     their effect.  Openpl must be used before any of the others
     to open the device for writing.  Closepl flushes the output.

     String arguments to label and linemod are null-terminated,
     and do not contain newlines.

     Various flavors of these functions exist for different out-
     put devices. They are obtained by the following ld(1)
     options:

     -lplot  device-independent graphics stream on standard out-
	     put for plot(1) filters
     -l300   GSI 300 terminal
     -l300s  GSI 300S terminal
     -l450   GSI 450 terminal
     -l4013  Tektronix 4013 terminal
     -l4014  Tektronix 4014 and 4015 terminals with the Enhanced
	     Graphics Module (Use -l4013 for 4014's or 4015's

     On many devices, it is necessary to pause after erase(),
     otherwise plotting commands are lost.  The pause is normally
     done by the tty driver if at login time, tset found a df
     field in the termcap(5) entry for the terminal.  If a pause
     is needed but not automatically being generated, add
	  flush(stdout);
	  sleep(1);
     after each erase().
