Generate Random Poisson Distrubution and Plotting.

Hi, I want to create a poisson distrubition with generating random numbers. I find some code in this site and make some modify

-------------------------------------------------------------
function S = PoissonSamp3(lambda,ns);
% -------------------------------------------------------------

S = zeros(ns,1);
for i = 1:ns    
    k = 0;
    produ = rand;
    while produ >= exp(-lambda)
        produ = produ*rand;
        k = k+1;
    end
    S(i) = k;
end
plot(S)

But this plotting like that;

In the internet I found that poisson distrubition should like that

So does anyone can some help me. Thak You
