[Paraview] Extract/plot data at a specified set of points

[Niccolò Bitossi]

Dear Paraview users,

I am post-processing an OpenFoam simulation.
I want to extract and possibly plot data (velocity magnitude, temperature, O2 concentration, etc.) at a specific set of points. They are in a number around 150 and form a polyline.
I just have the list of this series of points written in 3 columns (x,y,z) in a .csv (or .txt) file.

How can I do that?

Thank you.

Niccolò
