PLOT(3X)                GENIX Programmer's Manual                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-
           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  dev-
           ices. 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
