x1 = 0:10;
y1 = randi(100, 1, numel(x1));
x2 = 0:100;
y2 = randi(100, 1, numel(x2));
plot(x1, y1, x2, y2)

Have you tried simply hold on;
x = randn(100,1);
y = randn(100,1);
plot(x); hold on;
plot(y,'r');
Or simply:
plot(1:length(x),x,1:length(y),y)
If you need different scales for the y-axis see plotyy()
