Need help with simple pie chart

[Novella]

I need to bind to a simple pie chart and I don't seem to be having any luck, perhaps there is something I'm missing.
Basically, I have a collection of items with a property called "Status", which is a string. I want to create a pie chart that shows how many items have each "Status".  Here is what I've come up with, which just shows a solid blue circle.

<telerik:RadChart  ItemsSource="{Binding}">

    <telerik:RadChart.DefaultSeriesDefinition>

        <telerik:PieSeriesDefinition/>

    </telerik:RadChart.DefaultSeriesDefinition>

    <telerik:RadChart.SeriesMappings>

        <telerik:SeriesMapping>

            <telerik:ItemMapping DataPointMember="XCategory" FieldName="Status" />

            <telerik:ItemMapping DataPointMember="YValue" FieldName="Status" AggregateFunction="Count" />

        </telerik:SeriesMapping>

    </telerik:RadChart.SeriesMappings>

</telerik:RadChart>

Hello Novella,

When binding the control to a custom object, you will need to properly set the mappings. Additional information on this is available in the following topic:

http://www.telerik.com/help/silverlight/radchart-populating-with-data-data-binding-with-manual-series-mapping.html

When binding to a colleciton, you can take a slightly different approach, as shown in the following article:

Also, you will need to ensure, that the field which you use for the y value has a numeric value, which can be used by the control to show.
I hope this information helps.

I've got the similar problem... :(

Sorry. Fixed with changing mapping.GroupingSettings.ShouldFlattenSeries to true.
