Plot Description:
This plot presents the yearly first or last date of a given high or low temperature along with the number of days that year above/below the threshold along with the cumulative distribution function for the first date! When you select a low temperature option, the season displayed in the chart and available download spreadsheet represents the start year of the winter season. Rewording, the year 2016 would represent the period of 1 July 2016 to 30 Jun 2017.3 Generated Chart
