Hi Ben,

Thanks for the suggestion. With Octave 3.2.3, I get the following error
message:

octave:1> h = [1 2; 3 4];
octave:2> bar(h, 'stacked')
octave:3> legend('Apples', 'Oranges', 'location', 'northwest')
octave:4> set (gca, 'children', flipud (get (gca, 'children')))
error: set: new children must be a permutation of existing children

Cheers,
Shaun
