Plot Description:

This chart presents the daily frequency of the given date having the prescribed number of previous days above or below some provided treshold. Autoplot 216 provides actual streaks and yearly maximum values.

The accumulated precipitation metric is for an inclusive number of trailing days evaluated at that given day, so there is not double accounting for days that participate in a trailing day period that ended in the future. Rewording, an example frequency of 25% of May 1 would indicate that on that date, it had an inclusive trailing number of days accumulation above or below the choosen threshold.

2 Oct 2023: The plotting logic was updated to plot the frequency of a given day participating in a streak, rather than the frequency of a streak ending on that day. This should be a more useful metric for the user.

Based on a sampling of recent timings for this application, plot generation time has averaged 3 seconds. Hold on for the plot is generating now!
