first of all I’m new with Grafana and I’m using it to display power consumption.
The “series”, for now, is composed by the voltage value measured every 10s with a Raspberry and a SDM120, the database is InfluxDB.
I’ve been able to build a dashboard with a panel (line type) and 3 singlestat “gauge” that report current voltage, min voltage and max voltage.
I would like to add to the “line graph” a “red point” that highlights the max voltage and one for the min voltage.
I added a “B” query (SELECT max(“value”) FROM “voltage” WHERE time >= now() - 1h) and tried to “add override” in the “series overrides” but the only result that I had is to change color to the existing graph.
How can I have a second graph on the same panel?
Thank you, regards.
