Do you use Latex formatting? Then the labels appear correctly on the  
screen but disappear in the saved plot:

%  LaTeX-labels disappear in saved plot

ff=@(x,y) x.*y;

[X,Y]=meshgrid(linspace(-2,2),linspace(-2,2));
Z=ff(X,Y);
contour(X,Y,Z,42);
xlabel('x_1');
ylabel('x_2');
title('LaTeX formatting: x_1\times x_2');
print -dpng ff.png


I have Octave 3.0.0 for Mac OS X (10.4.11 PPC) from octave.sf.net  
with gnuplot (bundled with octave) and X11 plotting terminal.
