Calculate a weekly mean

This example calculates a temperature weekly mean and stores it in a separate bucket.

The following query: - Uses filter() to filter the average_temperature measurement. - Uses range() to define a time range. - Uses aggregateWindow() to group average temperature by week and compute the mean. - Sends the weekly mean to a new bucket (weekly_means)

option task = {
  name: "weekly-means",
  every: 1w,
}

from(bucket: "noaa")
  |> filter(fn: (r) => r._measurement == "average_temperature")
  |> range(start: 2019-09-01T11:24:00Z)
  |> aggregateWindow(every:  1w, fn: mean)
  |> to(bucket: "weekly_means")
