That's actually quite simple: you do that by not restarting gnuplot for 
every plot.  You have to keep a gnuplot process open, and generate fresh 
plots by sending it new commands from time to time, typically through a 
pipe fed by another process.

-persist is exactly the option you should not use.  That's used to keep
gnuplot's graph windows open indefinitely.  That's working in the exact
opposite direction of what you were trying to do.

That doesn't make any sense at all.  That 'replot' doesn't achieve 
anything useful.
