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

The SCIFastMountainRenderableSeries can be used to render a high performance iOS Mountain or Area Charts 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, SCIXyyDataSeries (uses Y1 only) or SCIOhlcDataSeries (renders close).

Tip!

By setting Stroke you alter the line color, Fill alters the fill. The Mountain-Series supports semi-transparent and LinearGradientBrush fills and looks great!
