Chop Data builds a selection list by repeatedly getting and skipping so many data points.
Chop operates on the Data Source. That means for most situations you should make sure Data Source is "File" so there's no surprises. Data Source: "List" allows some fancy tricks, like transforming a selection list to make a new list with just points 100-200 of each selection.
