Generates an Android Mountain Chart in code. See Documentation on how to use this type here: The Android Mountain Chart Documentation

The FastMountainRenderableSeries can be used to render an XyDataSeries (which contains one X-point and one Y-point), XyyDataSeries (renders Y values), XyzDataSeries, HlDataSeries and OhlcDataSeries(renders Close values).

Tip!

– To alter the line color, provide a pen by the setStrokeStyle() method.
– Calling the setAreaStyle() alters the fill.
– The setIsDigitalLine() method makes the series digital. The Mountain-Series supports semi-transparent and gradient fills and looks great!
