[Paraview] VTK: Re(z), Im(z) plotted as |z|^2, arg(z) ?

Hi, I'm having that very simple legacy VTK file (STRUCTURED_GRID) with one big block of SCALARS with two components, representing the real part and the imaginary part of complex values z. The values that are interesting for plotting are |z|^2 and arg(z), which of course can be entirely expressed
