PLOT(3X)                                                              PLOT(3X)



NAME
       plot: openpl et al. - 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-inde‐
       pendent 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 output devices.
       They are obtained by the following ld(1) options:

       -lplot  device-independent  graphics  stream  on  standard  output  for
               plot(1) filters
       -l300   GSI 300 terminal
       -l300s  GSI 300S terminal
       -l450   DASI 450 terminal
       -l4014  Tektronix 4014 terminal
