Hello, if you have an array like
A = [69.1687 67.7771 68.3709 70.7292 70.8961 65.8046 66.6392 74.2880 69.9386 69.7100 66.2853 67.0199; 68.0923 66.0579 66.2874 69.2144 65.8344 65.6781 67.8803 73.7639 67.3430 67.1914 67.3368 66.7132];
you can use,
plot([A(1,:);A(2,:)]);

For the example that i already give you can use,
plot(A(1,:),'b');
hold on;
plot(A(2,:),'r');
hold off
You can apply it to your case.
