You can retrieve data from database using a technology of your choice (like Ado.NET, Linq to SQL, Entity Framework, etc.) and store this data in objects. Then you can bind your RadChart to the collection of these objects and set the SeriesMapping accordingly. Here
you may find helpful information how to populate RadControls with data. You may also take a look at our RadChart documentation where we demonstrated how to bind RadChart to Northwind sample database using WCF service
or ADO.NET Data Service
. There are also online examples
with source code provided of RadChart databound to an SQL datasource.
Please note that consuming data from SQL database is beyond the support scope of our RadChart control.
If you have some concrete question regarding one of our controls , do let us know and we'll be glad to help.
