Yes, Power BI allows you to directly visualize anomalies within your reports and dashboards using the "Find anomalies" feature available in the Analytics pane of line charts. When enabled, this feature overlays detected anomalies on the chart as distinct markers, typically with a different color or shape, making them easy to spot. These markers can be customized and come with tooltips that explain the anomaly, such as the expected range and the actual value.
For the most effective visualization, use line charts with time-series data, as Power BI’s built-in anomaly detection is optimized for temporal patterns. The anomalies appear automatically once you activate the feature, and users can interact with them via tooltips or by using the “Explain anomaly” option, which opens an AI-generated breakdown of potential influencing factors.
While bar charts don't natively support anomaly detection, you can simulate similar behavior using DAX measures and conditional formatting to flag unexpected values. Additionally, for enhanced customization, third-party custom visuals like Charticulator, Deneb, or HTML Content visual can be used to highlight anomalies in more creative ways, such as dynamic color changes, annotations, or alerts embedded in visuals.
