I’ve got two time based series, and I want a graph of them multiplied together. Spent a fair bit of time searching, but no luck. Data is stored in influxdb, coming from an openhab install.
I can get the two series shown separately easily enough
SELECT “value” FROM “Solis_AC1Volt” WHERE $timeFilter
SELECT “value” FROM “Solis_AC1Amp” WHERE $timeFilter
but I want to display a graph of the power generated (Volts * Amps)
Can this be done in grafana?
