The simplest way is to reshape the data so that you plot multiple columns simultaneously, like this:

x = 1:400;
y = x.^1.5;
plot(reshape(x,80,5), reshape(y,80,5))

If you need more control, you can either use the line command, or plot with hold on.

There's two ways to do this:

(1) Reshape your vector so that it's a 80-by-5 array and call plot once

plot(reshape(yourVector,80,5))

(2) Use hold on to make sure plots get added, not replaced
