How does the new "Degree Days" line work?

I noticed the new Degree Days line in the Thermostat summary graph, but I don’t understand what it’s telling me.

Thanks in advance.

Here’s an article I put together to help answer that. Let me know if you have any other questions!

Oh, looks like you have since fixed the graph. As you can see in the screenshot, I was getting 57 and 23 degree days for heating and cooling, which did not seem right and made me wonder if I was misinterpreting the data. The same day now shows as 5.7 and 2.3, so I guess it had been erroneously multiplied by 10.

As I was writing the article I noticed the error.
