* XyNDataSeries is a DataSeries for holding X, and an arbitrary number of sets of Y values in SciChart's 2D

* @remarks
*
* A DataSeries stores the data to render. This is independent from the {@link IRenderableSeries | RenderableSeries}

*
* See derived types of {@link BaseDataSeries} to find out what data-series are available.
