It reduces values within a specified region using `regionReducer` (defaulting to mean) and across years with `yearReducer` (also defaulting to mean). The x-axis represents the day of the year (from `startDay` to `endDay`), the y-axis represents the derived band values, and the series represents band names. Users provide an ImageCollection and optional region, reducers, scale, and day range.\n"]]
