WPF Chart Change Series Type
// 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.
Demonstrates how to change how a series type is rendered in code. This is achieved by manipulating the SciChartSurface.RenderableSeries collection at runtime. The same thing can be achieved in MVVM, using our new MVVM SeriesBinding Markup Extension.
Click on a series to select it. With the series selected, change the Series Type via the dropdown.
Note: this example uses the HitTest API with interpolation to allow selecting of a series via mouse-click anywhere on the line, column or area.
// Source Code
The C#/WPF source code for the WPF Chart Change Series Type 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).
