    Hi, I'm trying to create a simple Doughnut Pie chart, I was checking the silverlight demo gallery but the code doesn't shows me how to do it because is already done inside class SeriesExtensions.GetUserRadialData.
    Could you please tell me how to create manually this kind of chart?

    For example I have these categories with values:

    Apples, 59
    Oranges, 30
    Lemon, 40

    I need to represent these values with a legend, series and titles.
    Thank you very much.

    Hello Chris,

    You can achieve the desired functionality like this:
    DataSeries series = new DataSeries();
    series.Definition = new DoughnutSeriesDefinition();
    series.Add(new DataPoint(59) { LegendLabel = "Apples" });
    series.Add(new DataPoint(30) { LegendLabel = "Oranges" });
    series.Add(new DataPoint(40) { LegendLabel = "Lemons" });
    RadChart1.DefaultView.ChartTitle.Content = "Chart Title";

    Also, you can find more information on populating the chart control with data here (the DataPoint / DataSeries objects work in the same way for all series types, it is the SeriesDefinition that provides the series-specific information).

    Hope this helps.
