Hi @nym2834610! We’re glad you’re finding 3D Flex useful!
For your first question, that plot is created manually. We do not know of a good way to generate such plots algorithmically. For instance, the curved arrows shown are meant to indicate a rotational movement, which would depend on the trajectory through the latent space (as you hint at in your second question), and there’s no way to know the optimal trajectory without manual inspection.
If you require a 2D summary of the results, the best method is probably to inspect the volume series and manually construct a figure that you feel best summarizes the movement.
Similarly, for your second question, there’s probably not a “best” way to display or inspect these latent spaces. Their non-linear nature (summarized here) makes it challenging to find a best path. I would guess that manual inspection of several trajectories would be necessary to find the most informative path.
I am sorry to not have the plot generation methods you were hoping for, but I hope that is helpful nonetheless!
