Generates an iOS Digital (Step) Line Chart in code. See Documentation on how to use this type here: The iOS Digital Line Chart Documentation.

The SCIFastLineRenderableSeries can be used to render a high performance iOS Line Chart in either Swift or Objective C. SciChart iOS supports millions of points out of the box, and is suitable for use in real-time scientific, medical and trading applications.

Data is provided by a DataSeries, e.g. the SCIXyDataSeries, XyyDataSeries (uses Y1 only) or SCIOhlcDataSeries (renders close).
