.TH PLOT 1 .CT 1 comm_dev graphics .SH NAME plot \(mi graphics filters .SH SYNOPSIS .B plot [ .BI -T terminal ] .SH DESCRIPTION These filters read plotting instructions (see .IR plot (5)) from the standard input, and in general produce plotting instructions suitable for a particular .I terminal on the standard output. .PP If no .I terminal type is specified, the environment parameter .L TERM (see .IR environ (5)) is used. Known .I terminals are: .TP .B 2621 .PD 0 .TP .B hp Hewlett-Packard screen terminal. .PD .TP .B 4014 .PD 0 .TP .B tek Tektronix 4014 storage scope. .PD .TP .B troff Convert to .IR troff (1) input. .TP .B 5620 .PD 0 .TP .B jerq Teletype DMD display under .IR mux (9.1). The filter persists after plotting, to make a layer that skips downloading on subsequent plots. .PD .TP .B 750 .PD 0 .TP .B pen Hewlett-Packard pen plotter. .PD .SH FILES .nf .F /usr/lib/plot/hpplot .F /usr/lib/plot/trplot .F /usr/lib/plot/penplot .F /usr/lib/plot/tek .F /usr/jerq/bin/jplot .fi .SH "SEE ALSO" .IR plot (3), .IR plot (5) .SH BUGS A persistent .I plot layer on a 5620 terminal imitates .LR "term 33" , it loses most abilities of a .IR mux (9.1) layer; see .IR term (9.1). .br Which plotters are known depends on which computer you are on.
