WPF Digital Line Chart
// WPF Chart Examples
SciChart WPF ships with hundreds of WPF Chart Examples which you can browse, play with, view the source-code and even export each WPF Chart Example to a stand-alone Visual Studio solution. All of this is possible with the new and improved SciChart WPF Examples Suite, which ships as part of the SciChart WPF SDK.
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.

// Source Code
The C#/WPF source code for the WPF Digital Line Chart example is included below (Scroll down!).
Did you know you can also view the source code from one of the following sources as well?
- Clone the SciChart.WPF.Examples from Github.
- Or, view source and export each example to a Visual Studio project from the SciChart WPF Examples suite.
- Also the SciChart WPF Trial contains the full source for the examples (link below).
