AI-generated Key Takeaways
-
The function generates a chart from an ImageCollection, plotting derived band values within a region for each day of the year.
-
The chart's X-axis represents the day of the year, and the Y-axis represents the derived band value, with band names as the series.
-
The function returns a
ui.Chart.
- 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).
- Series: Band names.
Returns a chart.
