Calculate a weekly mean

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

The sample query performs the following operations:

• Uses filter() to select records with the average_temperature measurement.
• Uses range() to define the start time.
• Uses aggregateWindow() to group records 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")
