Easy Tech TutsHow to Do Anomaly Detection in Power BI Visuals (Built-In AI Feature) Easily 2026
By Impran M N
Spotting irregularities in your data manually is slow and easy to miss, but Power BI's built-in AI anomaly detection can flag unexpected patterns automatically. This guide covers how to turn on and interpret anomaly detection within your visuals. It's a valuable feature for anyone doing fraud checks, quality control, or general performance monitoring.
01Access the AI features in Power BI
Locate the built-in AI options within your visual's settings, where anomaly detection can be enabled.
02Set up anomaly detection visuals
Apply anomaly detection to a time-based visual, such as a line chart, so Power BI can flag data points that deviate from expected patterns.
03Interpret detection results
Review the flagged anomalies to understand why they were marked as unusual and whether they represent a real issue worth investigating.
04Apply detection to business use cases
Use anomaly detection in scenarios like fraud checks in financial data or quality control in manufacturing metrics.
05Integrate with other Power BI features
Combine anomaly detection with alerts or other visuals so unusual patterns get surfaced as part of your broader reporting workflow.
