I think I have seen this before, but, ...

octave:11> x=1:.1:pi;
octave:12> plot(x,sin(x))
octave:13> print("sin.png", "-dpng")
octave:14>

When I open sin.png with eog, the axis labels are OK, but, the plot is just a black square.

I have something set wrong, but, what?

octave:14> version
ans = 4.1.0+
