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-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 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
