Hi Meenakshi,

You can include the three series in a stacked/stacked100 scenario, and following their order, the third will be positioned on top. Can you let me know how this approach meets your requirements?

Hello Meenakshi,

You can show the Data3 as a Label of the Second Series in your StackedBar chart. To achieve it  create a chart databound using  a list of business objects. In order to map to such kind of business objects, you have to create a new instance of SeriesMapping. Each SeriesMapping has ItemMapping property. For each ItemMappings the following properties are set - DataPointMember and FieldName which specifies from where the data should be taken. You can find more information about this in our help article - http://www.telerik.com/help/silverlight/radchart-populating-with-data-data-binding-with-manual-series-mapping.html
 To set the mathematical function (CustomLabel = (data1/(data1+data2))*100) to the Label property just add it in the constructor of your class:

public class Company
        {
            public double CustomLabel { get; set; }
            public double Value1 { get; set; }
            public double Value2 { get; set; }

            public Company(double value1, double value2)
            {
                Value1 = value1;
                Value2 = value2;
                CustomLabel = (value1/(value1+value2))*100;
            }
        }

You can find a sample project attached demonstrating the mentioned approach.

I hope this is helpful.

All the best,
