Hi, I have a ML job with a bucket span of 5 minutes. when an anomaly is detected and displayed in a graph, the red dot is the beggining of that bucket span? or the end of the bucket span? in other words the red dot indicates that the previous 5 minutes where anomalous or the following 5 minutes are anomalous? ![image](https://us1.discourse-cdn.com/elastic/original/3X/d/9/d99aab5c7fab3f81c4f38032c1da95a193a22212.png) ---

the `timestamp` written for the anomaly is for the time that is the beginning of the bucket span Therefore, an anomaly with a `timestamp` of `13:50:00` and a bucket span of `5m` will mean that the anomaly occurred in the 13:50:00-13:55:00 range ---
