Generates a Digital (step) Line-Chart in code using the FastLineRenderableSeries.IsDigitalLine property.

Digital line series can be used to render an XyDataSeries, XyyDataSeries (uses Y1 only) or OhlcDataSeries (renders close).

Tips!

As well as Stroke, you can set StrokeThickness, AntiAliasing, IsVisible properties to change how the series is rendered.

You can add data-point markers to a line series using the PointMarker API. This is very performant and uses the same bitmap rendering as our Scatter-Charts.
