Window calculations provide the capability to apply specific computations to measure values and allow you to perform different analytical tasks such as computing running totals, percentages of totals, differences, etc.
To create a window calculation, invoke the Binding menu and click the required measure. In the invoked data item menu, go to Calculations and select one of the available calculations.

After you have selected the required calculation, you can change its default settings by clicking the Edit button (the icon). This invokes the window containing common and specific calculation settings.
The dashboard control does not allow sorting by measures with applied Window Calculations since the calculation value can depend on the calculated element position.
