Ya, that one isn’t quite clearly labeled. The rest of the charts and data points make sense. Since it looks like this is a 5 day forecast I am guessing that the shaded green area is the historical average high/low temperatures for that date/time wherever this is in the world. The forecast is saying that the temp is expected to be 49°F on 11/1 at 2:07pm which is 9°F lower than the historical average so there looks like there will be a lesser chance of spotting deer according to the top graph. I guess? It would help to see the source page for context/additional info.
Lol - ya, location makes a difference. I am now also curious what that is supposed to represent. I looked on their website but since I don’t have an account all I could see was mostly marketing and sales info. There was a FAQ about that feature with a youtube video that might explain the data points but the video opened with a 2.5 minute ad so I bailed… can’t believe there are 3rd party adds on a video from a company’s help section! The iOS app store lists the rut map/forecast as a feature but that’s it. The app does look pretty sweet though - I’ll have to tell my brother about it.
