| Here is more information. It's 20,000 2D vectors, which are to be
| histgramed. But I need to see whether the histgram depends on the

Ok. Assuming you take the easy route and just store these 20,000 vectors
in a single field (something like the following) you can just use Slab to
pull out contiguous groups of position vectors from your vector field.
