How do I join the data points?

Hi,

I am given a problem where I have to plot the orbit of a function cos(x). I want to join the data points so that a line goes through each point.

Here is my code:

function cos_orbit(x, N)
for i = 1:N
    y = cos(x);
    hold on
    plot(i, x, 'b.')
    x = y;
    hold off
end

Calculate everything first and plot() it later.
