Thank you in advance.

Include 1.05*signal and 0.95*signal in the same plot.

One final question. How can i check if a random signal is between the limits? How can detect it or mark in the plot! Can i do this with a code or are some predefined commands? My signal is for a 19894*2 double. Thank you.

If S_rand is the random signal 19894x2 matrix, you can sort out the points where this signal is not in the prescribed limits by
S_out = S_rand( S_rand(:,2) < 0.95*S(:,2) | S_rand(:,2) > 1.05*S(:,2) )
where S is the 19894x2 matrix of the original signal.
