Plot Description:
The frequency of days per year that the temperature was above/below average. Data is shown for the current year as well, so you should consider the representativity of that value when compared with other years with a full year's worth of data.This app gets a bit tricky to understand the interplay between direction and magnitude. For example, if you pick -5 degrees as the magnitude and then an above departure, you get the data domain of departures ranging from -5 to positive infinity. If you pick the absolute value departure, then you can do the combination of departures of both sides of average.
