How to plot a shifted signal?

I'd like to shift any signal, be it periodic or non-periodic without using in-built functions like circshift(). How would I do this? I'm seeking to understand shifting conceptually and would love to have code examples.

One way:

t=linspace(0,2*pi);
y=sin(t);

plot(t,y,t-pi/2,y,'x'); legend Original Shifted
