Plotting in real time

[Sig L. <sig...@gm...>]

I would like to plot data in real time. I am not sure if this is
possible but I would like to have time on my X axis, and various
values on Y. I know this could be possible by tailing the last "20
entries" of a file and then feeding that into gnuplot, but was
wondering if there was a better way.

Has anyone any other alternative than feeding gnuplot a "plot
'myfile.txt' with lines" every update interval?

I tried feeding data into gnuplot via a fifo but graphing didn't start
until the fifo was closed on the  writing end. Is there a way around
that?

I understand that gnuplot would have to shift the graph or redraw the
entire thing, this may not have been considered when designing.


TIA,
