Displaying bands in a time-series chart?

I’ve been using Grafana for 60 whole minutes. Very impressed so far.

From an InfluxDB source I’m plotting indoor temperature. I would like to display banded sections of the chart that overlays if/when the air conditioning is running during those periods. How do I do this in Grafana?

In my database, I have a history of when the air conditioning conditioning changes states between “idle” and “cooling” (string values).
