I’m assuming this is due to a truncation behaviour, but given a query roughly in the form:
from(bucket:"my-bucket")
|> range(start: -6d)
|> aggregateWindow(every: 3d, fn: sum)
why do I end up with three rows?
e.g. running this today (1st of December) gives me rows with a _time column
2022-11-27 00:00:00 GMT
2022-11-30 00:00:00 GMT
2022-12-01 15:25:22 GMT
What I want to get is two values - one for the last three days (or whatever period) and one for the previous period of the same length. How can I achieve this?
