How do I time shift an audio signal?

So I've got this audio signal I've wanted to shift to the right but I can't seem to reach it.

I've tried adding zeros but no shifting occured.

load handel.mat

filename = 'handel.wav';
audiowrite(filename,y,Fs);
clear y Fs  

[y,Fs] = audioread('handel.wav');  

N = length(y);
t = (0:N-1)/Fs;
Z = zeros(N,1);

subplot(2,1,1);
plot(t,y);
xlabel 'Time'
ylabel 'Audio signal'
grid on

subplot(2,1,2);
Ynew = [Z;Fs];

When you select the second subplot, you need to use the plot command again to plot the audio signal.

Here's a modified version of the code.

load handel.mat

filename = 'handel.wav';
audiowrite(filename,y,Fs);
clear y Fs  

[y,Fs] = audioread('handel.wav');  

N = length(y);
t = (0:N-1)/Fs;
delay2 = 3*Fs;
Z = zeros(delay2,1);

subplot(2,1,1);
plot(t,y);
xlabel 'Time'
ylabel 'Audio signal'
grid on

subplot(2,1,2);
Ynew = [Z;y(1:end-delay2)];
plot(t,Ynew);
xlabel 'Time'
ylabel 'Delayed Audio signal'
grid on
