[Mis]understanding graph data

The screenshot shows result and graph definition, except for what you cannot see. Graph definition also sets Time Frame to Last 420 Days.
I do not understand why the daily temperature plot in green could be higher than the min/max range in red. This seems to occur from about June through October. I do notice in colder months the green line tends to hug the bottom of the min/max, but in summer months it exceeds the top of the min/max.
Question: how is a day's worth of data calculated to yield the daily temperature value, and why would it be higher than the day's max value?
Another question: Is it possible within Meteohub to sample and graph a month this year and compare it to the same month last year? I think the answer is no. Exporting data and analysis offline is the way to go.
