Hi there,
    I'm facing three issues as, (as MVVM, I'm not using CodeBehind)
    I've single row result set, which query back from Domain Service. How do i bind that 1 row data into PieChart (I want to show Column name as Legend)?
    Another question is, How can I show % information beside Legend name? (eg, First Test 20.00% in ledgent area)
    Last question is, How can I bind that % information into Textbox beside Legend.


Here is my Code (but not working)

and I don't know how to show % beside Legend and how to put TestBox for That % information at Legend Area.

Please advise and I'm uploading sketch images.
Thanks.

Hi qwer,

 1. How do i bind that 1 row data into PieChart (I want to show Column name as Legend)?
I am not sure what you are using to get the data but  here is a nice blog post about using RIA services with RadChart: http://blogs.telerik.com/vladimirmilev/posts/10-07-15/silverlight_radchart_codeless_binding_to_ria_services_domaindatasource.aspx

2.How can I show % information beside Legend name? (eg, First Test 20.00% in ledgent area)
This is not supported by the RadChart legend. What I would do is put the chart in a canvas, then put a grid in the canvas and position it just next to the legend. Make 4 row grid and put the information you want into labels.

3.How can I bind that % information into Textbox beside Legend.
I believe this is the same question as the second one. When you get a DomainDataSource object as a DataContext for the whole form you can easily bind it to any UI element. I believe that a grid with labels is a better option than a textbox.
