Hi,
the function works on a discrete amount of data. Hence every call to it replaces the values used first time around.
I've attached an example in LabVIEW 7.0 that uses a pulse generation vi to allow the manipulation of the array sent into the integral object, and then it's easy to calculate what the integral of the data would be.
Hope that helps
