I just discovered that [gnuplot][] has an `xterm` terminal output mode
which uses [xterm][]'s tektronix emulator ([since gnuplot
4.2.6][release]).  This is useful if you have logged into a remote
machine and want to plot something, but you didn't have the foresight
to use `ssh -Y` to bring along a connection to your X server.  I used to use

    gnuplot> set term dumb

but often the low resolution available with standard terminal
characters left the resulting output almost unintelligible.  With

    gnuplot> set term xterm

your `xterm` will pop up a new window in tektronix mode, in which you
get very nice monochrome graphics.

Besides the “forgot to tunnel X” use case outlined above, this output
would also be useful if you wanted to avoid exposing yourself to [[X
vulnerabilies|X_hacks]] while logging into an untrusted machine.

Obviously, you'll have to be running `xterm` for any of this to work ;).
