Not really.  gnuplot doesn't do real-time plotting.  It can be plenty 
fast, but it won't do any sliding-window buffering of a continuous input 
stream for you.  You would have to do that yourself (e.g. by filling a 
file with the "little of the past" you want to display), and keep on 
sending "replot" requests to gnuplot to update the display.
