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 writing. Closepl flushes the output.
FILES
/usr/lib/plot.aproduces output for plotting filters
/usr/lib/vt0.aproduces output on vt0 storage scope
/usr/lib/gsip.aproduces output on Diablo terminal
/usr/lib/tek.aproduces output for the Tektronix 4014 terminal
