| There is a but in your version of octave. Try this ...

It should also work if the order is
hold on
x = -10:0.01:10;
plot (x, sin (x));
plot (x, cos (x));
hold off
If that's not working properly, then there is a bug, but I don't know
what would be cuasing it. It works properly for me with
Octave 3.0.4, 3.1.54, and the current development sources. Does my
simple example above that plots sine and cosine waves work for you?
