Only for some subset of the various meaning that term has been given, by
various people, over time.

This won't work.  Gnuplot never "receives" data (i.e. it doesn't have
any way to push data into a running session).  It "requests" data, if
and when you give it a {|s|re}plot command.

So the "receiving" will have to be done by some other program, which can
then remote-control an instance of gnuplot through a command pipe,
sending it "replot" commands or complete new plot commands every once in
a while.
