Previous versions of Octave saved data to a temporary file, then sent the
filename to gnuplot.  But that caused trouble because there was no way
for Octave to know when it was safe to delete the temporary file.  To
fix that problem, Octave now sends all data to gnuplot in the same
stream that is used for plotting commands.  That avoids the need for
temporary files, but unfortunately, gnuplot is unable to zoom with the
mouse when it is used this way.  So when the problem is fixed in
gnuplot, zooming will work again.  But given the long release cycle of
gnuplot, I don't expect a fix soon (but maybe a gnuplot developer is
reading this and would like to comment).
