The chart is a timeseries of rainfall with data coming from the Dayfile. Every day it rained it is plotted in the chart as column.
The cumulative value of the rain starts january 1 at zero and augments with every amount measured until 31 december after which it resets to zero.
Also visible is a [https://en.wikipedia.org/wiki/Moving_average#Simple_moving_average_(boxcar_filter) moving average] with a [[Charts#PeriodMovingAverage|configurable period]] (default is 180 days).
If the value of the inifile parameter ''UseNormalRainReference'' is ''Normal'' the user sees a red dotted horizontal line at the Y-axis value of the Normal total rainfall per year. When ''UseNormalRainReference'' is ''StationAverage'' the user sees a green dotted line ate the value of the calculated average total rainfall for the station. And obviously when the parameter value is both, the user sees both lines.
