DESCRIPTION
These functions generate either a device-independent graphic stream
(see plot(5)) or device-dependent graphics commands. For device-inde‐
pendent graphic stream, include file <plot.h> for floating point argu‐
ments; and file <iplot.h> for integer arguments. The libraries for
different devices are loaded with the following ld(1) flags:
-lplot general stream output
-l2621 HP2621 terminal
-l4014 Tektronix 4014 terminal
-lram Ramtek 9300 display
-ltr Troff input, tuned for the Mergenthaler Linotron 202 phototype‐
setter
-lpen HP7580 pen plotter
-lblit blit terminal running mux
-l5620 5620 terminal running mux
String arguments are null terminated and may not contain embedded new‐
lines. For details on string arguments, see plot(5). Poly, fill, and
the various spline functions take an integer array and an array of
pointers to double floating point arrays. The integers specify the
number of vertices (x-y pairs) in the floating point array. The last
integer entry should be 0.
