RadChart is responsible for creating the DataSeriesCollection and for this reason the DataSeries
property of the ChartArea is read-only. Generally, you can add/remove/modify series in this collection, but you cannot initialize it. Still, you can set the ItemsSource
property with any observable collection, which contains the data you need to show. This collection does not need to be a DataSeriesCollection, but it could be a collection of custom objects. RadChart provides convenient mapping mechanism for databinding in such scenarios. You can take a look at these help topics:

for more details about databinding RadChart. Even though this is an example of RadChart for WPF, the approach shown there is applicable in RadChart for Silverlight. Hope this helps.
