Zooming and Scrolling API
Documentation
This example demonstrates how you can connect the Chart and RangeSelector widgets 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.
