MATLAB: Plotting from a for loop- discrete maps

MATLABplottingvector

I'm just playing around with discrete maps (i.e. the logistic map). I seem to be having an issue plotting my data; It seems to only plot the last data point. Any suggestions?
function [x] = logistic(lambda,x0,n)
x(1) = x0;
for i= 1:n
    x(i+1) = lambda*x(i)*(1-x(i));
    z = [i,x(i)];
    disp(z);
end
plot(z,'+');
end
Thank you in advance

function [x] = logistic(lambda,x0,n)
x(1) = x0;
for i= 1:n
    x(i+1) = lambda*x(i)*(1-x(i));
    z(i,:) = [i,x(i)];
    disp(z);
end
plot(z(:,1),z(:,2),'+');
end
