Stacked Column, Bar and Radar-Column series
        in the ASP.NET AJAX Chart can be clustered in groups
        since the Q3 2013 	release.
    
    
        Series that will be stacked in a separate group
        must have the same group name set in their  	GroupName property.
        If the property is left blank, all series will be placed in one default stack. Setting
        the GroupName property of any series automatically sets the
        Stacked property of the  	first series to true, so it is not required
        to be explicitly set.

    You can further examine the stacking of Series in the Stacked Series example.
    Optionally, you can also use the StackType property to change the stack type from the default (Normal) type to Stack100, which will lead you to a 100% stacked chart. More about the  		Stack100 type is explained in the Stacked 100% Series demo.
