ui.Chart.image.doySeries

  • 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.

Generates a Chart from an ImageCollection. Plots derived values of each band in a region for a each day of the year.

  - 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.
