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

[William Oquendo]

Hi, thanks for your response.
Yes, I have tried it, and although useful for the statistics, like average
velocity magnitud, still does not allow
me to extract what I really need, like the sum of every mass*|V|^2 for all
particles as a function of time, and,
in general,  a global function (a function which depends on all the
particles) as function of time (array which
seems to be hidden).
Do you or anybody know if it is possible to configure the "Plot Selection
Over Time" filter to add it some
other function? or, is it possible to use the Python Calculator filter for
this? can someone share and example?
Thanks again for your kind response.
