Average Calcuation

Hi
Could you please think about adding a section in the "Calculation Area" to show the average of the selected range based on the definite integral.
Actually, by selecting the calculation of definite integral, the area under a curve (or points series) will be shown. If we divide this calculated area by the x-length (i.e. X2-X1) it will give us the average of the Y in the selected range based on the Integration method.
Thanks for your support.
