RDK direction of the coherence dots in degrees

I want to let the signal dots move together in same direction. I change the coherence from 0to 1. but I didn’t see any changes in the experiment.
even I change the coherence to 1 ,I didn’t see the dots move together in the same direction obviously

looking forward to your help sincerely.

Do the dots move at all?
If not, can you please include your experiment here so we can take a look?


The points can move, but they don’t move in the same direction consistently.I read in the reference manual that “This value can be set using the dir property after initialization.”, but I don’t quite understand it. In addition,my experiment is not finished yet, so I’m sorry I can’t show it. Finally, thanks for your reply.
