Visualizing the particle trajectories- in particle tracing for fluid model

Hi,

My fluid flow model and particle tracing module work fine. BUT problem in post-processing is:

I released 4 particles (using massless formulation) in 3D model, from -5[cm] relative to the surface boundary/ vertical height is around 12[m].

My question is that: How is it possible to plot and visualize the particles trajectories with line?
Is it possible to show them in 2D cross section? How? Is there any example?

I attached my model here.

Hope to hear your answers.
Thanks
