tag. --> Below are a couple of plots of the logistic equation:

Xn+1 = k(Xn)(1-Xn)

The left hand equation is a cobweb plot.  The parabola

y = k(x)(1-x)

is shown and the positive diagonal.

The cobweb plots Xn versus Xn-1 with stops along stops on the positive diagonal. 

The right hand is an interation plot.  You can adjust k and the first value in the interation (technically Xo).
