    RadChart rcOTDBar = new RadChart();
    List<ChartData> objList = _objBLL.GetData();
    rcOTDBar.DataSource = objList;

    rcOTDBar.DataGroupColumn = "Group"; // "Grade A", "Grade B", "Grade C"

Hello Michelle,

 There is no need to use Grouping to achieve your scenario. The grouping feature should be used when you have repeating values in a column of your datasource. It creates as many series as the number of distinct values in this column. For more information, you can review our documentation.
To have stacked bars as shown on your sample image you may follow our help topic and demo. The topic demmonstrates how you can bind a single series to a List of objects. However to have stacked bars with three bars in a stack , you will need three series. The approach is absolutely the same, but you should extend the Product class in the topic with two more int properties (for the two more bar series). Of course, you'll need to populate the collection of instances of the Product class with your new data.
Finally just set the Type of the series to StackedBar and Voilà.
