Calculation

The Calculation control is a helper that performs mathematical computations on numerical data from a dataclip. Unlike visual controls, it doesn’t render anything on the dashboard: it produces a value that other controls, such as Gauge or Delta, can consume.

Setting	Required	Description
Calculation type	Yes	The operation to apply: Sum, Min, Max, Average, or Count.
Mapping	Yes	How data is selected: Datapoints or Reference.
Datapoints	Conditional	One or more numerical columns from a dataclip; all their values are included in the calculation.
Reference	Conditional	A single column from a dataclip; all its values are included in the calculation.

Either Datapoints or Reference must be configured. The result recalculates whenever the underlying dataclip data changes, and there’s no user interaction involved.

Typical uses: an aggregated total or average feeding into a Gauge, a target or threshold value, or a comparison value for a Delta control.

Tips

• Make sure every selected field actually contains numerical values.
• Use Datapoints to combine multiple columns into one calculation, and Reference to aggregate across all rows of a single column.
• Centralize a calculation here instead of duplicating the same logic across multiple visual controls.

Limitations

• Only basic aggregations are supported (Sum, Min, Max, Average, Count): no custom formulas or expressions.
• No event handling or user interaction.
