Answer
Creating a custom anomaly detection alert in Looker Studio involves setting up a visualization that highlights data points deviating from expected patterns. This can be done by using calculated fields and conditional formatting to identify anomalies.
- Sign in to your Looker Studio account.
- Create a new report or open an existing one where you want to add the anomaly detection.
- Add a chart (e.g., line chart) that represents the data you want to monitor.
- Create a calculated field to define the anomaly condition (e.g., data point exceeds a certain threshold).
- Apply conditional formatting to the chart to visually highlight anomalies based on your calculated field.
Additional Comment:
- Use calculated fields to define what constitutes an anomaly, such as deviations from a moving average.
- Conditional formatting can be applied to change colors or add markers to highlight anomalies.
- Regularly review and adjust your anomaly criteria to ensure it remains relevant to your data trends.
