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.
