Generates a Chart from an image. Extracts and plots the value of each band in one or more regions.
- X-axis = Band labeled by xProperty (default: band name). - Y-axis = Reducer output. - Series = Region labeled by seriesProperty (default: 'system:index'). Returns a chart. | Usage | Returns | |---|---| | `ui.Chart.image.regions(image, *regions*, *reducer*, *scale*, *seriesProperty*, *xLabels*)` | ui.Chart | | Argument | Type | Details | |---|---|---| | `image` | Image | Image to extract band values from. | | `regions` | Feature\|FeatureCollection\|Geometry\|List\[Feature\]\|List\[Geometry\], optional | Regions to reduce. Defaults to the image's footprint. | | `reducer` | Reducer, optional | Reducer that generates the value(s) for the y-axis. Must return a single value per band. | | `scale` | Number, optional | The pixel scale in meters. | | `seriesProperty` | String, optional | Property to be used as the label for each region in the legend. Defaults to 'system:index'. | | `xLabels` | List\[Object\], optional | A list of labels used for bands on the x-axis. Must have the same number of elements as the image bands. If omitted, bands will be labeled with their names. If the labels are numeric (e.g., wavelengths), x-axis will be continuous. |
