Use Range Selection for Filtering
Documentation
The RangeSelector widget allows you to handle changes of the currently selected range. For this purpose, the callback function is specified in the onValueChanged option. This demo illustrates how to use the newly selected range for filtering data.
Feel free to share demo-related thoughts here.
