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.
An introduction to the UIElement Annotations API, which allows WPF UIElements to be placed over the chart at specific X and Y data-values.
Annotation Types Include:
– AxisMarkerAnnotation
– BoxAnnotation
– CompositeAnnotation
– CustomAnnotation
– HorizontalLineAnnotation
– LineAnnotation
– LineArrowAnnotation
– TextAnnotation
– VerticalLineAnnotation
