How to use a multi dimensional array

I am trying to populate the grid using an array with four dimensions. Any ideas

sequence

The 4th dimension isn't time??? Maybe three is enought.

I did some test few months ago, you can try the 3rd dimension (deep)
with multiple grids, but I found that pass 25 of them is a big deal, so went back to just one grid and reload data as it where multiple.
