Grafana in Factry Historian | Repeat by Variable

In this tutorial, we show how to build dynamic, scalable dashboards in Grafana using the “Repeat by Variable” feature — a key tool when working with data from Factry Historian. Instead of manually duplicating panels for each machine, asset, or production line, this feature allows you to define a variable (e.g., machine_id, line, or asset_group) and automatically generate repeated panels for each value.This is particularly useful in batch manufacturing or environments with a high number of similar assets. The video walks through a real example: setting up a dashboard where each production line gets its own panel for temperature, pressure, or OEE metrics — using one query and layout structure. You’ll also see how to improve navigation with dropdowns, how template variables interact with your Factry Historian time series queries, and how this fits within a broader Grafana dashboarding strategy for factories.The result? A dashboard that adapts to the context selected by the user, improving usability for operators, engineers, and team leads — without having to create dozens of static views.
