Real-time plots under X11/Exceed

[<pa...@mi...>]

Hi,
I would appreciate answer to following problem related to fast updated
real time data.

I plot an ASCII file using a "plot" command. Upon arrival of new data
(with a frequency close to 1 second) I issue a "replot" command.

In effect I see that gnuplot_x11 takes al large amount of CPU resurces 
(no matter if the gnuplot is iconified or not).

Worst, when X11 is displayed on a PC through an emulator Exceed, Exceed
runs
out of memory (or so it says) no matter how it is configured.

Questions are
  1) What is the best way to use gnuplot for real-time visualization
  (are there any buffering options reducing resouces needed for redraw)

  2) How to iconify gnuplot windows (other through -noraise option)
   so when window is inconified gnuplot does not eat X11 resources.


Thanks

 Pawel
