Yeah, I don't think the other line styles work at the moment.

This actually works for me, using gnuplot 4.2 with octave 2.9.13 on 
Ubuntu linux. I'm guessing that this is a problem with gnuplot. Perhaps 
AquaTerm acts different from WxTerm?

You can also set colors as RGB triblets. That is to plot a red line you 
could do
  plot(x, y, "color", [1, 0, 0])

Perfect matlab compatibility will never be achieved, but we are pretty 
close to matching the most commonly used commands.
