Hi,

Could you explain what you are doing differently than this sample, for example:

        <igChart:XamWebChart x:Name="theChart" >
            <igChart:XamWebChart.Axes>
                <igChart:Axis AxisType="PrimaryX">
                    <igChart:Axis.Label>
                        <igChart:LabelGroup Format="{}{0:MMM-dd}" Angle="90"/>
                    </igChart:Axis.Label>
                </igChart:Axis>
            </igChart:XamWebChart.Axes>
            <igChart:XamWebChart.Series>
                <igChart:Series ChartType="ScatterLine" 
                                DataSource="{StaticResource data}"
                                DataMapping="ValueX = DateTime; ValueY = Value"/>
            </igChart:XamWebChart.Series>
        </igChart:XamWebChart>

Code behind:

public partial class MainPage : UserControl
    {
        public MainPage()
        {
            InitializeComponent();
        }

    }

    public class TestData
        : ObservableCollection<TestDataItem>
    {
        public TestData()
        {
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2006, 10, 6),
                Value = 1
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2006, 11, 6),
                Value = 2
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2006, 12, 6),
                Value = 3
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 1, 6),
                Value = 1
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 2, 6),
                Value = 2
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 3, 6),
                Value = 3
            });
            Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 4, 6),
                Value = 1
            }); Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 5, 6),
                Value = 2
            }); Add(new TestDataItem()
            {
                DateTime = new DateTime(2007, 6, 6),
                Value = 3
            });

        }
    }

    public class TestDataItem
    {
        public DateTime DateTime { get; set; }
        public double Value { get; set; }
    }

Thanks,
