WPF Chart Secondary Y-Axis
// 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.
A static example which demonstrates a line chart with two series and primary and secondary Y-Axis. SciChart supports unlimited left and right Y-Axes and this example shows in a simple way how to register a line series on each axis.
Also see the Drag Area to Zoom, Drag Axis to Scale examples to show how to add interactivity to a dual-axis application.
Tip!
The properties NumericAxis.AxisAlignment, NumericAxis.Id and FastLineRenderableSeries.YAxisId / FastLineRenderableSeries.XAxisId show how to align axes and assign series to them.
