For context on this, being able to look at value based anomalies on grouped by data is a critical feature, not just for us I’m sure. Take an example where you have sensors deployed in the real world gathering data, and you have a monolithic table in your database that stores data from all sensors, we’d like to use the column anomaly features in Elementary to look at the quality of each individual sensor over time, which we would be able to do if there was an implementation of this Github feature request. Happy to discuss!
