It lets you pick two date ranges and view them in the same graph, so you can see the difference instead of switching back and forth between two views. It is available in the graphs for **Electricity**, **Gas**, **Compressed Air**, and **Water**. ![](https://support.sensorfact.eu/hs-fs/hubfs/image-png-Sep-03-2026-03-15-04-0001-PM.png?width=670&height=222&name=image-png-Sep-03-2026-03-15-04-0001-PM.png) ### Why use Compare dates? - **Check whether a change worked:** Compare the weeks before and after you adjusted a machine, a shift pattern, or a setpoint. - **Spot creeping consumption:** Compare this month against the same month last year to catch a slow increase that a single view hides. - **Compare like with like:** Line up two production weeks with similar output to see which one ran more efficiently. ### Step-by-Step Instructions 1. Open the graph for **Electricity**, **Gas**, **Compressed Air**, or **Water**. 2. Open the **interval selector**. 3. Enable the '**Compare dates**' toggle. 4. Enter the **start date** and **end date** of your first range. 5. Enter the **start date** and **end date** of your second range. *Note: both ranges must be the same length. A single range can cover up to 1 year.*  ![](https://lh7-rt.googleusercontent.com/docsz/AD_4nXdjQamnRW0aOkZzHBYrGnXqoK_HL9iowTQMRKVcJGpI3mYV7QQ_aotRwnA9HVrP_30gz-S922w3GQB6FwXY7H5Z3HtsSFmkq3Q0Wn9taL4zh2R1yapetO_PPNbIWNVuHVNpCVyU37JTuB6-lOft13enuag?key=DLFpfpMo6HbUHh4VlzNsOA) 6. Click '**Apply dates**'. ### What if it doesn't work? - **A red message says the intervals have to be the same length** — your two ranges differ. Adjust one of the end dates so both cover the same number of days, then apply again. - **The comparison looks odd even though the ranges match** — check that both cover comparable production. A holiday week compared against a full production week shows a large difference that has nothing to do with the change you made. - [Hardware & Installation](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#main-content) - [Energy Management](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#energy-management) - [Gas Management](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#gas-management) - [Predictive Maintenance](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#predictive-maintenance) - [Water Management](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#water-management) - [Compressed Air Management](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#compressed-air-management) - [OEE](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#oee) - [Temperature & Humidity](https://support.sensorfact.eu/knowledge/hardware-installation?hsLang=en#temperature-humidity) - [Dashboard & Insights](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#main-content) - [Energy management](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#energy-management) - [Compressed Air](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#compressed-air) - [Overall Equipment Effectiveness (OEE)](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#overall-equipment-effectiveness-oee) - [Reports](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#reports) - [Alerts](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#alerts) - [Ultrasonic Water](https://support.sensorfact.eu/knowledge/dashboard-insights?hsLang=en#ultrasonic-water) - [Advice & ROI](https://support.sensorfact.eu/knowledge/advice-roi?hsLang=en#main-content) - [Energy Management](https://support.sensorfact.eu/knowledge/advice-roi?hsLang=en#energy-management) - [Predictive Maintenance](https://support.sensorfact.eu/knowledge/advice-roi?hsLang=en#predictive-maintenance) - [Compressed Air Management](https://support.sensorfact.eu/knowledge/advice-roi?hsLang=en#compressed-air-management) - [Account & Billing](https://support.sensorfact.eu/knowledge/account-billing?hsLang=en) - [Troubleshooting](https://support.sensorfact.eu/knowledge/troubleshooting?hsLang=en#main-content) - [Energy Management](https://support.sensorfact.eu/knowledge/troubleshooting?hsLang=en#energy-management) - [Gas / water pulse Management](https://support.sensorfact.eu/knowledge/troubleshooting?hsLang=en#gas-water-pulse-management) - [Ultasonic Water Management](https://support.sensorfact.eu/knowledge/troubleshooting?hsLang=en#ultasonic-water-management) - [Product Updates](https://support.sensorfact.eu/knowledge/product-updates?hsLang=en#main-content) - [Release Notes 2025](https://support.sensorfact.eu/knowledge/product-updates?hsLang=en#release-notes-2025) - [Release Notes 2024](https://support.sensorfact.eu/knowledge/product-updates?hsLang=en#release-notes-2024) [![sensorfact\_new\_logo](https://support.sensorfact.eu/hubfs/00.%20Archive/sensorfact_new_logo.svg "sensorfact_new_logo")](https://www.sensorfact.eu) Copyright © 2026, Sensorfact
