On-the-fly calculations

August 4, 2026

Until now, series in the explorer and in line/bar chart widgets as well as the single value and gauge chart widgets could only show measurements directly, optionally aggregated across subjects. With this feature, currently in beta, you can now combine and transform those series using the same calculation language that powers calculated metrics.

In the explorer, adding a series now gives you the choice between a measurement series and a calculation series. Once you’ve added at least one measurement series, you can reference it by its letter (a, b, c, …) in a calculation to derive a new series from it. The same capability is available in the single value, gauge chart, and line and bar chart widgets that display measurements, so you can show calculated results directly on a dashboard without first creating a dedicated calculated metric (and thus without the costs of extra usage for series or measurements).

A common use case is tracking KPIs on the fly, such as an efficiency ratio (e.g. heat output divided by electricity consumption), a load factor (e.g. average load divided by peak load), or a loss indicator (e.g. the difference between inflow and outflow measurements).
