Ben,
This patch to the legend script:
http://hg.savannah.gnu.org/hgweb/octave/rev/9f34f7636fe0
fixed the case of horizontal string cells, but not vertical string cells. Try
something like:
x = [0:0.1:1]';
Y = [x sin(x)];
C = {'x', 'sine'};
plot(x, Y, '-');
legend(C);
pause;
C = {'x'; 'sinusoid'};
legend(C);
I've attached two patches to pick which way to fix this. Either with a rot90()
or indexing backward through the cell... I suppose one should try
legend('x', 'sin(x)');
to make sure the order is also correct for non-cell entries. (I don't have a
recent version on this machine.)
Dan
