[Paraview] How to compute functions for all particles and plot as function of time

[William Oquendo]

Dear all,
I have a system of particles printed on vtp files. I am visualising them on
Paraview, and want to analyse some dynamic info. Each particle has its own
position and velocity vectors, and mass (scalar) as well, plus some other
scalars and vectors not relevant now. Let/s say that I want to plot the
*total* kinetic energy as a function of time. I was able to plot the
individual kinetic energies per particle for each time (using the
calculator and plot data filters), and also to plot the kinetic energy for
a single selected  particle as function of time (after selecting the
particle and using the plot selection over time filter). But I haven't
found how to use the Python calculator or similar to compute that aggregate
quantity (total kinetic energy in this example), and to plot it as a
function of time.
Any help is greatly appreciated.
