Hi, I’m trying to statically visualize the movement of an object on a camera screen by overlaying some arrows showing the movement direction. They may overlap and have different lengths. According to the docs, this should be possible with VectorField, but I can’t seem to get the option rescale_lengths=False to work. What am I missing here?
