[net.micro.pc] plot

unfres@hscfvax.UUCP (Janet) (12/03/85)

	I am trying to use the plot(3X) graphics library on the Vax.  I
would like to load my program with the device-independent plot library (-lplot)
and then run it with a filter specific to my terminal, e.g.,

		cc -o program program.c -lplot
		program | plot -Ttermtype

as described in the UNIX manual (BSD 4.2).
	My problem is that there are only four or five different terminals for 
which filters are provided, none of which I have.  Specifically, I would like
to run my program using an IBM PC/XT or a DEC Professional as my terminal.  Does
anyone know of additional plot filters or device-specific plot libraries that
are compatible with plot(3X)?
					
				Thanks,

Postnews seems to have eaten the signature on my original article...

P.S.  I've heard of a database called "graphcap" that might contain
the necessary info to adapt standard UNIX(TM) routines for other terminals.
Anyone know about it?

Unlike a Tektronix or VT-240 terminal, the IBM PC/XT and DEC Professional
have no built-in graphics sequences.  Interpretation of graphics codes
is entirely dependent on whatever virtual terminal program that
you're running on the PC or PRO, or on the terminal emulation
that is provided by the operating system.

If you're running VENIX on the PC/XT or PRO, my suggestion is to
down-load your program and simply link it with the console plotting
filter provided by VENIX (-ltpc on the PC, or -ltpro on the PRO).
