- What Grafana version and what operating system are you using?
Grafana v10.2.3 - What are you trying to achieve?
I measuring the daily consumption of my coffee machine and would like to sum up the daily values to calculate the total consumption of the heater. I have following data:
Day 1: 5
Day 2: 4
Day 3: 6
Day 4: 5
Now, I would like to sum up the individuals values so that I arrive at 20 and then display it on a bar chart
- How are you trying to achieve it?
from(bucket: “iobroker”)
|> range(start: -10d, stop: v.timeRangeStop)
|> filter(fn: (r) => r[“_measurement”] == “Coffee”)
|> filter(fn: (r) => r[“_field”] == “value”)
|> aggregateWindow(every: 1d, fn: max, createEmpty: false)
|> sum()
|> yield(name: “max”)
This does the calculation (see below) but I am not able to put this on a chart.
- What happened?
When I try to display a chart, I get the following message
