Currently on InfluxDB v2.0.5 and using Grafana v7.5.6 for visualization. I originally posted this question on Grafana forum thinking this would be solved with Grafana transformations, but I’m now thinking it may be better solved with Influx.
I need a movingSpread() function that will work similar to movingAverage() except it returns the spread
from(bucket:"mybucket") |> range(start: v.timeRangeStart, stop: v.timeRangeStop) |> filter(fn: (r) => r["_measurement"] == "TimeDomain") |> filter(fn: (r) => r["Channel"] == "Ch0") |> filter(fn: (r) => r["_field"] == "value") |> movingSpread(n: # of points) |> yield()
Is something like this possible? If so, does anyone have any pointers on how I could create this function? I’m currently going through the docs but the dots are not connecting for me yet. Thank you!
