Discrete Axis Zooming and Panning
Documentation
Discrete data support is one of many strengths of the Chart component. In this example, you can zoom data in the Chart using another DevExtreme JavaScript UI component, the RangeSelector.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
