Re: octave's graphics interface / linux operating system

[etienne]

  Hi all,

I was in Dieter's situation last year, and I took the same path. That is,
writing a few functions to save data and call gnuplot (code available at [1]).

  I wasn't aware of the drawnow trick, which indeed seems to offer means to
customize the output. I also see the online documentation is fairly recent,
maybe it is time for me to switch back to out-of-the-box octave plotting
functions.

  Cheers,

  Etienne

# I use
#
# drawnow ("x11", "/dev/null", false, "file.gp")
#
# that creates a file called file.gp with the raw gnuplot commands that
