Date-Time Scale
Documentation
In this demo, data used to define the RangeSelector scale comes in the string type. However, there is the valueType property that specifies the actual scale data type. As this property is set to «datetime», the string data will be cast to the date type.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
