Pie Chart in MVVM

[Muthukumar]

hi team,
i need to develop a simple pie chart. but i have only below code in my Xaml. i need to create and control series from my viewmodel not in the code behind. And also i need to control the series colors, number of legends and legend colors from my viewmodel. if u guys give the sample code would be the great help. 

The idea is i need to have only one template and use that control as common control.
need to show that more that one pie chart in the same page.

 <telerik:RadChart x:Name="RadChart1" ItemsSource="{Binding Data}">
            <telerik:RadChart.DefaultSeriesDefinition>
                <telerik:PieSeriesDefinition>                
                </telerik:PieSeriesDefinition>
            </telerik:RadChart.DefaultSeriesDefinition>
        </telerik:RadChart>

Hello Muthukumar,

You can find a similar example in our legend features demo - the Pie chart is created using MVVM, with different legend options. As for the series colors, please, refer to this example.

hi ,
thanks for ur reply. In this above example i can bind the legends from viewmodel, but Color palettes are from code behind
i need that too from view model and another thing if i create color palettes from codebehind it is very slow. Is there any way to do that in viewmodel.



thanks,

Hi Muthukumar,

Yes, it is possible to bind the colors using MVVM as well - please, have a look at this thread for more information on the matter and sample code.
