NAME
     plot - graphics interface subroutines

USAGE
     openpl ()

     erase ()

     label(s)
     char *s;

     line(x1, y1, x2, y2)
     int x1, y1, x2, y2;

     circle(x, y, r)
     int x, y, r;

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

     move(x, y)
     int x, y;

     cont(x, y)
     int x, y;

     point(x, y)
     int x, y;

     linemod(s)
     char *s;

     space(x0, y0, x1, y1)
     int x0, y0, x1, y1;

     closepl ()


DESCRIPTION
     These subroutines generate graphic output in a relatively
     device-independent manner.  Space must be used before any of
     these functions to declare the amount of space necessary.
     See plot(4).  Openpl must be used before any of the others
     to open the device for writing.  Closepl flushes the output.

     Circle draws a circle of radius r with center at the point
     (x, y).

     Arc draws an arc of a circle with center at the point (x, y)
     between the points (x0, y0) and (x1, y1).

     String arguments to label and linemod are terminated by
     nulls and do not contain new-lines.

     See plot(4) for a description of the effect of the remaining
     functions.

     The library files listed below provide several flavors of
     these routines.

FILES
     /usr/lib/libplot.a  produces output for tplot(1G) filters

     /usr/lib/lib*.a     various device-specific filters

WARNINGS
     In order to compile the program file.c that uses these func-
     tions, it is necessary to use the -lplot option to cc(1).

     Before you can execute the output of such a compilation, you
     must pipe it through tplot.

     The above routines use <stdio.h>, which causes them to
     increase the size of programs, not otherwise using standard
     I/O, more than might be expected.
