- X-axis = Band labeled by xProperty (default: band name).
- Y-axis = Reducer output.
- Series = Region labeled by seriesProperty (default: 'system:index').
Returns a chart.

| Argument | Type | Details |
|---|---|---|
image | Image | Image to extract band values from. |
regions | Feature|FeatureCollection|Geometry|List, 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, 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. |
