record/view steering vectors (not resultant vector)

Hi, I am trying to record the steering vector of a flock using locust.

I have tried inputting a display vector after the steering components which produces vectors but they originate from the initial position (as showing in one of the images attached).

What I am looking to do is record the steering vectors from each point as it moves

I also have attached a document showing what the components of locust are used for.

Thank you

Sarah
