`ValueError: array of sample points is empty` when plotting trajectories (e.g., in SuperAnimal inference)

Is there an existing issue for this?

I have searched the existing issues

Bug description

When plotting trajectories of a bodypart where no predictions are made (or all are below the plotting threshold), matplotlib versions 3.7.0 and 3.7.1 fail with error ValueError: array of sample points is empty.

This issue cannot be reproduced with matplotlib<3.7.0 and matplotlib>=3.7.2 (it was fixed by matplotlib/matplotlib#25978).

Operating System

macOS

DeepLabCut version

dlc version 2.3.8
