I too am not crazy about autoreplot.  I find it odd to set the title and
labels after plotting.  As you say, takes some getting used to I guess.

Binary data can also be fed to gnuplot via the pipe.  However, I didn't
want to mess with Octave innards if possible; plus pipes seem sometimes a
bit dodgy across platforms.
