x = 1:10;
y1 = 2*x;
y2 = 3.5*x;
% error
dy = y2-y1 ;
% Multiple plot commands, with "hold" on
figure
hold on
plot(x,y1,'r');
plot(x,y2,'b');
plot(x,dy,'g');
%
legend('Signal1','Signal2','error')

KSSV needed some data for illustration purposes, so he created a range of x from 1 to 10, and created one line as 2*x and a second line as 3.5 * x. In your actual code you would replaces those three lines with your own data.
