Hi,
I am trying to make an animated plot with gnuplot controlled from a
python program. The problem is I did not find a command to sync with
gnuplot. More precisely my program looks like this:
while True:
write data to 'file.dat'
plot 'file.dat' with gnuplot
wait a little
the problem is in 'wait a little'. Sometimes, gnuplot is too slow, and
does not plot 'file.dat' fast enough. So the file may be destroyed
before it is plotted. What I would need is a command that would wait for
gnuplot to finish plotting. Is there such a command ? I could not find it.
It should be easy to implement. Just send 'echo "sync"' to gnuplot, and
wait for a line with "sync" in return.
I will probably implement this myself.
I found some interesting ideas there:

Maintainers of gnuplot-py may wish to implement these functions. It
seems very convenient, and easy to implement.
