It is possible.  See "help set term x11"

From the manual:
 The `x11` terminal can connect to X windows previously created by an outside
 application via the option `window` followed by a string containing the
 X ID for the window in hexadecimal format.  Gnuplot uses that external X
 window as a container since X does not allow for multiple clients selecting
 the ButtonPress event.  In this way, gnuplot's mouse features work within
 the contained plot window.

I suspect that is an overly complicated way of achieving the effect
you want, but it's certainly one possible approach.

Another possible approach is to have each CALL SYSTEM(...) trigger an update
of an *.eps or *.png file on disk.  Then you just leave ghostview or an image
display program running continuously, set to update the screen display whenever
the underlying file is re-written.
