But this looks as if my application would have to
run gnuplot in popen() and not vice versa?

Currently I run a number of scripts in plot
where each script delivers data for a part graph.

It would be nice to be able to access these values
from the script which runs inside

plot "<script"

or am I misunderstanding?
