Good point!

I tend to forget that there is a life beyond the keyboard -- I was using
CTRL+L which naturally doesn't make any sense to the "vttek terminal"

I'm a lot more interested in the capabilities of xterm's 4014 emulation
than gnuplot per se, but I must say that with even my very elementary
notions of mathematics gnuplot is a lot of fun.

What I find rather surprising is that I'm in an xterm window in VT mode
... then I start gnuplot and set term to vttek .. then do something like
a "splot sin(x) * cos(x) / tan(x)" or whatever .. and all of a sudden my
VT window/terminal becomes a graphic display .. now there's some magic
here that I don't understand.

To me that's the hard part .. with the countless samples I found in the
various gnuplot galleries .. and all the scripts that go with them ..
not to mention the excellent tutorials .. learning gnuplot should really
be a breeze!

At this point and following the above sequence .. everything works very
smoothly .. the only thing that the tek emulation does not appear to
have is color(s) .. presumably the original tektronix terminal did not
have that either.

Also, I'm curious of the possibility of using the tek emulation to
graph something like my CPU utilization or network activity in "real
time" on the terminal. I've written a few awk one-liners that display
the numbers on my gnu/screen status line - so I can tell at a glance
what's going on .. and I was thinking it would be cool to do the same
thing "graphically".

Thanks for your tips and apologies for my total ignorance and dumb
questions.
