It would, of course, help to see the script, but I can guess what the
issue is.
Try doing
use Demeter qw(:ui=screen);
at the top of the script, and
$data_object -> pause;
before it exits.
The specific message is issued because the perl script ended while the
pipe to the gnuplot process was still open. That doesn't happen if you
put in a pause. And you get to look at the plot before it vanishes!
