Why is labview so slow when I use an array subset to scan through a large array

[Beaton]

I am using an array sub set to scroll  arrays across an intensity graph, and it works but when I load a large array (ex. 482 x 1000) the program is extremely slow, updating appox. every 3 seconds. What I'm I doing wrong?

Can you attach your code so we can see how you do this?

How big are the subsets you are extracting?

Never mind, found a simpler way to accomplish my task, Thanks anyways
