plot(3X)                                                 plot(3X)



NAME
     plot - provide graphics interface subroutines

SYNOPSIS
     int openpl()

     int erase()

     int label(s)
     char *s;

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

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

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

     int move(x, y)
     int x, y;

     int cont(x, y)
     int x, y;

     int point(x, y)
     int x, y;

     int linemod(s)
     char *s;

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

     int 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 newlines.

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

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

WARNINGS
     To compile a program containing these functions in file.c,
     use

        cc file.c -lplot


     To execute it, use

        a.out | tplo

     The above routines use <stdio.h>.  Therefore, the size of
     programs not otherwise using standard I/O is increased more
     than might be expected.
