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 undo/redo Zoom and Pan (Zoom History) by using the ZoomHistoryManager type.
The ZoomHistoryManager is attached to the chart via the SciChartSurface.ZoomHistoryManager property.
All zoom, pan operations then become tracked, and you can Undo or Redo zoom via the ZoomHistoryManager.Undo and ZoomHistoryManager.Redo methods.
In MVVM Applications, you can also bind to and execute the ZoomHistoryManager.UndoCommand and ZoomHistoryManager.RedoCommand.
The C#/WPF source code for the WPF Chart Undo Redo Zoom 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 in the SciChart WPF Examples suite.
- Also the SciChart WPF Trial contains the full source for the examples (link below).
