These commands read plotting instructions (see
plot(5))
from the standard input or the specified
files,
and in general
produce plotting instructions suitable for
a particular
terminal
on the standard output.
The
-r
flag may be used to specify the device's output resolution
(currently only the Imagen laser printer understands this option).
If no
terminal
type is specified, the environment parameter
$TERM
(see
environ(7))
is used.
Known
terminals
are:
-4013
Tektronix 4013 storage scope.
-4014\&or -tek
Tektronix 4014 or 4015 storage scope with Enhanced Graphics Module.
(Use 4013 for Tektronix 4014 or 4015 without the Enhanced Graphics Module).
