Grafana v10.1.2 (8e428858dd) on a Raspberry PI 4
I want to do a monitoring of my heating system: Raspberry PI traces different values via MBus and modbus. Data is stored via IOBroker and influxDB. Visualization of actual values or values versus time works fine.
But if I want to plot e.g. power vs outside temp (XY Chart), I get an error message: ‘Y must be in the same frame as X’. This is probably because both time series have different time stamps.
Is there a possibility to add data points e.g. via interpolation for desired time values?
