Hello I’m completely new in influxdb. I have a time series which looks like this.
It represents the total of electric power consumption from my smart meter. I would like to get the difference between the last two values and make a graph in grafana.
8268.219 - 8268.218 = 0.001
How would you do that. Is there a nice query I can use in grafana or do I have to create a InfluxDB Task and make the calculation there?
Thank you very much for your answer.
