Zooming and Panning API
Documentation
This example demonstrates how you can connect the Chart and RangeSelector components in order to zoom into the appropriate data range within the Chart. Move the sliders along the RangeSelector, and you will note that the value axis of the Chart is adjusted automatically.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
