# Calculation Engine based on time range

My feedback is to include a PE type calculations in Coresight similar to Datalink.

The calculations should work with the time range selected.

Options should be similar to Datalink avg, min, max, total, range etc...

It would also be great to include basic arithmetic calculations to use against multiple PI Tag inputs and output the live calculation to a PI Value on screen.

e.g PI Tag A + PI Tag B
