ui.Chart.image.doySeries
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.
| Usage | Returns |
|---|
ui.Chart.image.doySeries(imageCollection, region, regionReducer, scale, yearReducer, startDay, endDay) | ui.Chart |
| Argument | Type | Details |
|---|
imageCollection | ImageCollection | The ImageCollection to chart. |
region | Feature|FeatureCollection|Geometry, optional | The region to reduce. Defaults to the union of all geometries in the image collection. |
regionReducer | Reducer, optional | Reducer for aggregating band values within the region. Must return a single value. Defaults to ee.Reducer.mean(). |
scale | Number, optional | Scale to use with the region reducer in meters. |
yearReducer | Reducer, optional | Reducer for aggregating regionReducer outputs across years (for a given day). Must return a single value. Defaults to ee.Reducer.mean(). |
startDay | Number, optional | Day of year to start the series. Must be between 1 and 366. |
endDay | Number, optional | Day of year to end the series. Must be between startDay and 366. |
