Dynamic Series from the DataSource
Documentation
In this example, data for series is provided in a peculiar manner. Each object in the data source represents a point in a single series. To define series in this case, use the seriesTemplate object where you need to specify the data field providing series names and custom settings for a given series. Settings common to all series must be set within the commonSeriesSettings object. Providing data in this manner is useful when the number of points within a single series changes over time.
