/**
* XyyDataSeries is a DataSeries for holding X, Y1, Y2 data in SciChart's 2D
* {@link https://www.scichart.com/javascript-chart-features | JavaScript Charts}
* @remarks
* The XyyDataSeries is primarily used with our {@link FastBandRenderableSeries | JavaScript Band Chart},
* which draws a High-Low fill between two lines, where the fill changes color depending on whether line Y2 > Y1
*
* A DataSeries stores the data to render. This is independent from the {@link IRenderableSeries | RenderableSeries}
* which defines how that data should be rendered.
*
* See derived types of {@link BaseDataSeries} to find out what data-series are available.
* See derived types of {@link IRenderableSeries} to find out what 2D JavaScript Chart types are available.
