Generates a Digital Mountain (Area) Chart in code calling the setIsDigitalLine(True) method on a FastMountainRenderableSeries.

Digital mountain charts 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).

Tips!

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!
