The following query uses the NOAA water sample data to display changes in water levels over time. Use level description as the Fill Column in the visualization controls.

from(bucket: "noaa")
  |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
  |> filter(fn: (r) => r._measurement == "h2o_feet")
  |> filter(fn: (r) => r._field == "level description")
  |> aggregateWindow(every: v.windowPeriod, fn: last, createEmpty: false)
