A Chebyshev curve $\cC(a,b,c,\phi)$ has a parametrization of the form $ x(t)=T_a(t)$; \ $y(t)=T_b(t)$; $z(t)= T_c(t + \phi)$, where $a,b,c$ are integers, $T_n(t)$ is the Chebyshev polynomial of degree $n$ and $\phi \in \RR$. When $\cC(a,b,c,\phi)$ is nonsingular, it defines a polynomial knot. We determine all possible knot diagrams when $\phi$ varies. Let $a,b,c$ be integers, $a$ is odd, $(a,b)=1$, we show that one can list all possible knots $\cC(a,b,c,\phi)$ in $\tcO(n^2)$ bit operations, with $n=abc$.
