Differentiate Series Function

The Differentiate series function is used to calculate finite differences of the data in the source series. This series function takes only one source series. The data in the value component of the destination series are the finite differences of the data in the function domain in the value component of the source series.

Four algorithms of calculating finite differences are supported (i.e. two-point forward difference, two-point backward difference, three-point central difference, and cubic spline) and can be selected on the Differentiation tab-page of the Series Function dialog box.
