Many times we need to load long-term image timing image charts to view changes in the past period of time. Here we will use (chart) chart analysis. What is the difference between doySeriesByYear and doySeries? Here we first look at two functions. When we have a loading limit, we can first reduce my date, because the images in a small area exceed 1,250 scenes in just 3 months, so when loading more than 5,000 images, the content loading cannot be completed. It will reflect the process of exceeding the limit.
ui.Chart.image.doySeries(imageCollection, region, regionReducer, scale, yearReducer, startDay, endDay)

X-axis: Day of year (startDay to endDay, defaults to 1 to 366).
-
Y-axis: Derived band value (reduced within the region and across years).
