Setting panel to show different values

I’m a beginner in Grafana. I use Grafana v 7.0.0 and Influxdb to show graphs (time series) & analyse the status of different devices inside my house.
I want to show in one pannel changing of two temperatures during the period when the heater is on. How to configure the Graph of the heater status (0, 1), to show the increase and decrease of temperatures inside the status (1).
I hope so I explained my problem as clear as possible :slight_smile:

How can I make this work?
