    Hi Telerik,

    I am gonna use RadChart for the first time in a Windows application using VB.Net.

    I need to display the pie chart for the total amount  with 7 divisions namely - Visa, Master, Amex, Cheque, Cash, Discover, Paypal.

    This is my stored procedure output -

    Amount     TenderType     NoOfPeople

    300.00      Amex                  2
    600.00      Cash                  4
    450.00      Cheque              3
    450.00      Discover             3
    300.00      Master                2
    300.00      Paypal                2
    300.00      Visa                    2

    The pie chart has to display Amount of the respective tendertype.   

    Plz help me with how to code and display in Windows application using VB.Net.

    Thank you in advance.

    Regards,
    Raj

    Hi Ves,

        That sample code worked and helped a lot to understand it. One small clarification - 

            Is it possible to show the pie chart section values as the pie chart label and the Types in legend?

            For Eg. Please see the attached image file in which I have used picture box as legends.

    Hi Raj,

    I am sorry for the delay. Please, find attached an updated version. By default RadChart will show the value as pie slice label, so I have removed the DataLabelsColumn setting. I have wired the ItemDataBound event and updated the Name property for every item.
