Easiest way to plot pointDisplacement

Hi!
I want to do a few heave decay test of some objects in 2D and 3D. However, I am not sure how to properly plot the displacement over time for the objects. If I for example look at the FloatingObject tutorial, what would be the best approach to plot its displacement over time? I'm mainly concerned with the vertical direction first, but for the 3D case I would like to plot for all three directions, plus pitch, heave and yaw.

Is paraView a good option, or will I have to write a script to read the sixDof output directly? If so, does anyone have any scripts available that could help me on my way?

Hi,

I use interFoam solver and if I have a bubble or a slug flowing within a channel, I use center of mass as a variable to describe the displacement.

I never used it for more complicated cases such as 2 slugs in a channel but i guess even that could be possible if some sort indexing can be given for individual entities.
