DESCRIPTION
These functions generate either a device-independent graphic
stream (see plot(5)) or device-dependent graphics commands.
For device-independent graphic stream, include file <plot.h>
for floating point arguments; 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
PLOT(3) PLOT(3)
-l4014 Tektronix 4014 terminal
-lram Ramtek 9300 display
-ltr Troff input, tuned for the Mergenthaler Linotron 202
phototypesetter
-lpen HP7580 pen plotter
-lblit blit terminal running mux
-l5620 5620 terminal running mux
String arguments are null terminated and may not contain
embedded newlines. 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.
