SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, and iOS Chart & Android Chart Components
WPF Chart Using Vertical Slice Tooltips Example
// 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 usage of VerticalSliceModifier for getting slices of series like when using RolloverModifier.
Tip!
You can add and remove slices on chart. Also you can click on vertical slice and drag it to change point of slice.
