    [Newbie question]

    Hi,

    I'm trying to set up a simple line chart.
    My code is very simple:

     

    DataSeries ds1 = new DataSeries();  
    ds1.LegendLabel = "Random";  
    ds1.Definition = new Telerik.Windows.Controls.Charting.LineSeriesDefinition();   
    FillDataSeries(ds1); // Fills series data points with XValue and YValue   
    chartArea1.DataSeries.Add(ds1); 

    When the code runs, a NullReferenceException is thrown.
    ----------------------------------------------------------------------------------------------------------

     

    System.NullReferenceException: Object reference not set to an instance of an object.

       at Telerik.Windows.Controls.Charting.BaseAnimationConverter.GetAnimationSettings() in c:\Builds\WPF_Scrum\Chart_WPF_2009_Q2_SP1\Sources\Development\Controls\Chart\Chart\Animations\BaseAnimationConverter.cs:line 163
    -----------------------------------------------------------------------------------------------------------

    what am I missing?

    Thanks.

    Hi Yoni Dagan,

    I see from your post that you have tried to use the ChartArea as a standalone control and populate manually its data series collection. This control was designed to be placed within a RadChart control and should  not be used separately. You can find more information on how to set up the chart control here.
