PLOT(3X)
NAME
openpl, erase, label, line, circle, arc, move, cont, point, linemod, space, closepl − graphics interface
USAGE
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 produce a device-independent graphics stream on standard output for plot(1) filters
-lgmr produce a DOMAIN 2D Graphics Metafile Resource (2DGMR) file.
