WPF Bubble 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.
As part of our WPF chart library, this generates a line and bubble series chart in code. The FastBubbleRenderableSeries requires an XyzDataSeries, which contains one Z-value per X-Y point.
Bubble sizes can be scaled using the ZScaleFactor property. In this example this is bound to a slider. Move the slider to see the effect!.
Tip!
If you share an XyzDataSeries between Line and Bubble Renderable Series, the line will render the X-Y points while the Bubble will render the X-Y-Z points.
