Generates a Chart from an image collection. Extracts and plots the value of the specified band in each region for each image in the collection. Usually a time series.
- X-axis = Image labeled by xProperty (default: 'system:time_start').
- Y-axis = Reducer output.
- Series = Region labeled by seriesProperty (default: 'system:index').
Returns a chart.
