RadChart supports data binding to various data sources and services. Moreover, RadChart can be used in two modes:
Automatic Series Mappings - simply set ReadChart.ItemsSource and RadChart will automatically create the needed series mapping. Use automatic data series mapping when you have simple data.
Manual Series Mapping - use manual series mapping for more complex business objects or when you want more control.
