Re: [Gnuplot-info] Plotting data file while writing to it

[Thomas S. <t.s...@fz...>]

create a file named e.g. plotloop.gpl :

   plot '< tail -n 99 datafile' using ...
   pause 10
   reread

let your program write its data into 'datafile' and start
the loop in gnuplot:

   load 'plotloop.gpl'

every 10 seconds gnuplot will plot the newest 99 datapoints.

gnuplot waits for an end-of-file or for a pipe being closed
before plotting anything, that's why a '< tail -f ...' doesn't work.
