DESCRIPTION
These subroutines generate graphic output in a relatively
device-independent manner. See plot (VI) for a description
of the meaning of the subroutines.
There are four libraries containing these routines, one that
produces general graphics commands on the standard output,
and one each for the vt0 storage scope, the Diablo plotting
terminal and the Tektronix 4014 terminal. Openpl must be
used before any of the others to open the device for writ-
ing. Closepl flushes the output.
FILES
/usr/lib/plot.a produces output for plotting filters
/usr/lib/vt0.a produces output on vt0 storage scope
/usr/lib/gsip.a produces output on Diablo terminal
/usr/lib/tek.a produces output for the Tektronix 4014 ter-
minal
