Users define `image`, `regions`, `reducer`, `scale`, and `xProperty`. It extracts band values, uses the provided `reducer` to compute a single y-value per band, which are then plotted as separate series. `regions` are labeled on the x-axis, based on the provided `xProperty`. The chart plots the reduced values per band in different regions, returning a `ui.Chart` object.\n"]]
