How to get text appearing within only one plot

I am meant to reproduce this image:

This is what I currently have:

This is my code:

t = linspace(0,2*pi,1000);

for n=1:5 %First row 1:1
    w = [1 1 1 -1 -1];
    d = [0 pi/4 pi/2 pi/4 0];
    x = sin(w(n) * t+d(n));
    y = sin(t);        
    subplot(8,5,n), plot(x,y)
    txt1 = '1:1'; text(0.5,0.5,txt1)
    axis([-1 1 -1 1]), axis square off
end

How can I get the text 1:1 to only appear in the left most image

t = linspace(0,2*pi,1000);
for n=1:5 %First row 1:1
    w = [1 1 1 -1 -1];
    d = [0 pi/4 pi/2 pi/4 0];
    x = sin(w(n) * t+d(n));
    y = sin(t);        
    subplot(8,5,n), plot(x,y)

      axis([-1 1 -1 1]), axis square off
  end
   txt1 = '1:1'; text(0.5,0.5,txt1)

Put your desired text out side the loop.

that puts it on the right side

Is there anyway to get it on the left? like:
