Because RadChart can be bound to objects that implement the IList interface, and generic lists implement IList, it follows that you can bind RadChart to generic lists. These lists can be of simple types, e.g. int and double types, or the lists can be composed of complex objects containing multiple properties.
See Data Binding RadChart to a Generic List of Simple Types for a minimal example binding to a list of type double.
See Data Binding RadChart to a Generic List of Objects for a more complex example where multiple properties are used for data and labeling.
