You may want to simplify this a bit:
xpra start ssh:SERVER:100 --start-child=xterm --exit-with-children
(no need to ssh, exit the xterm to stop the session)

Then you could also do this on the server after you "ssh -X":
xpra start :100
DISPLAY=:100 gnuplot
Then attach as normal.
The downside is that if your ssh connection goes down.. gnuplot will die.
But then you should be able to use screen or tmux to workaround that.
