Showcases how to synchronize axis ranges across multiple charts by sharing IRange instances. Two SciChartSurfaces are created and arranged vertically. This example shows how to synchronize Zoom, Pan, Axis Scale operations.

Tip!

The charts are synchronized by setting shared instances of DoubleRange as X-Axis VisibleRange and Y-Axis VisibleRange for both charts.
