InfluxDB v2.7.1
Grafana 10.0.1
I want to create bar graph monthly energy.
from(bucket: “IDA”)
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r._measurement == “Electric” and r._field == “P” )
|> aggregateWindow(every: 1mo, fn: sum, createEmpty: true)
|> drop(columns: [“host”, “topic”])
|> cumulativeSum()
My data is Active Power, P (kW).
P is send every 1 minute.
I want to convert P to Energy (kWh) and show on the graph.
Example graph that I want to get it
Another question, how can I offset -7h?
I try to use this “option location = timezone.fixed(offset: -7h)”
from this https://docs.influxdata.com/flux/v0.x/stdlib/timezone/fixed/
but I cannot offset it.

Here is what I do (not completely the same as what your query, but should help you get started):
from(bucket: "EIAtest7")
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r["_measurement"] == "ElectricPowerOperations")
|> filter(fn: (r) => r["_field"] == "value")
|> filter(fn: (r) => r["type"] =~ /^${type:regex}$/ )
|> filter(fn: (r) => r["region"] =~ /^${region:regex}$/ )
|> group(columns: ["region", "_measurement"], mode:"by")
|> aggregateWindow(every: 1mo, offset: 1d, fn: sum, timeSrc:"_start") // sums the total used per month
|> yield(name: "monthly_data")

Thanks for your help.
I updated my energy chart.
I change data from Power [kW] every 1 minute to Energy (accumulated) [kWh]
I can create daily energy chart but I still cannot create monthly energy chart (It does not show value on first month).
For someone who wants to create the graph like me.
option location = {zone: “UTC”, offset: 7h}
from(bucket: “IDA”)
|> range(start: v.timeRangeStart, stop: v.timeRangeStop)
|> filter(fn: (r) => r._measurement == “Electric” and
r._field == “actEnrg” )
|> aggregateWindow(every: 1d, fn: last, createEmpty: true, timeSrc: “_start”)
|> difference(nonNegative: true, initialZero: false, keepFirst: true, columns: [“_value”])
|> drop(columns: [“host”, “topic”])
