In this case, you can directly preset the datasource, to get data from the table in question. Let us assume that we have a table called "Products", which is part of the Nwind database. We can select a single column from the table, which would thus represent your layout. In the example below, the chart is bound to an AccessDataSource, but the same approach is valid for an sql connection as well:
<telerik:RadChart ID="RadChart2" runat="server" Skin="LightGreen" Width="450" Height="300" DataSourceID="AccessDataSource1" DefaultType="Pie">
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
SelectCommand="SELECT TOP 4 [UnitsInStock] FROM [Products]">
I hope this gets you started properly.
All the best,
the Telerik team
