The Argand diagram is used to display some characteristics of the Riemann ζ function. The zeros of the ζ function on the complex plane give rise to an infinite sequence of closed loops, all passing through the origin of the diagram. The behavior of the phase of the ζ function on and off the line of zeros is studied. Up to some distance from the line of the complex zeros, the phase angle is shown to still retain their memory. The Argand plots also lead to an analogy with the scattering amplitude and an approximate rule for the location of the zeros. The smooth phase of the ζ function along the line of the zeros is related to the quantum density of states of an inverted oscillator.
