    This example shows how an ASP.NET AJAX Chart can be bound to an ObjectDataSource. The ObjectDataSource uses a custom class Vehicle, which is declared in the App_Code directory of the website application. The major chart properties are:

    • DataSourceID in the main tag sets the declarative data source for the entire chart. The DataSource property can be used for a programmatic data source if you create the connection in the code-behind.
    • DataFieldY for the series to point it to the desired column of the data source.
    • DataLabelsField for the x-axis labels to populate the items for the axis (it can also be applied to the y-axis).
    • DefaultCS.aspx
    • Vehicle.cs
