WPF Chart Pan on Mouse-Drag
// 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 mouse-dragging of SciChart: Overlays three series on a SciChartSurface and applies the ZoomPanModifier. This is a built-in ChartModifierBase derived class which adds the behavior of panning on mouse-drag. ChartModifiers can be added to the SciChartSurface via the SciChartSurface.ChartModifier property, or via a ModifierGroup
Interactivity Options
Change input button to start the pan operation, e.g. Left, Middle button (WPF Only) or Right Button
