So I'm trying to plot a graph with the time as the x-axis, but I'm having a hard time trying to.

This is my code so far:

load handel.mat
filename = 'handel.wav';
audiowrite(filename,y,Fs);
clear y Fs  
[y,Fs] = audioread('handel.wav');  
plot(y);
xlabel 'Time'
ylabel 'Audio signal'

I'm still new to MATLAB so it's still not easy for me.

Thanks in advance

t=(0:length(y)-1)/fs;
plot(t, y);
