Monitor particle diameter and its frequency at a plane
 

I am trying to monitor a particle distribution at a plane in a pipe, so I would like to plot particle diameter on the x axis and frequency on the y.

I can plot particle diameter, but which options should I select for frequency?

And I also am currently plotting it for the whole pipe, not at a specific plane (I need to see how the distribution changes along the length of the pipe).

Hopefully that makes sense! I am grateful for any assistance you can provide!

Do you want to see the distribution of particle diameters on a plane in a pipe? You can try plot/x-y and then change x and y axis to position and particle diameter. If you want to see particle diameter from a track file then you need to select diameter in lagrangian phase/track file/diameter.
