Follow-up Comment #77, bug #47974 (project octave):

I missed the bug in #75, sorry.  Hmm, here's what is different between the two
files created with drawnow (there is another difference after the binary data,
but it looks fine):

I think that "palette" in line 11 is the source of the problem.  gnuplot is
expecting a third column for that style (the index to the color map).  I don't
see why we should be using the palette, however.  I'll have a look...
