Hello,

in our current project, I had to bind multiple series to a XamDataChart. So I ran into an issue, than when the series did not contain the same date time values an the same count of items, only the last series ist displayed. I am using the latest Infragistics 2012.2 Version .Net4.0 on Windows 7.

A short sample:

 public partial class MainWindow : Window
    {
        public List<Data> Series1 = new List<Data>();
        public List<Data> Series2 = new List<Data>();
 
        public MainWindow()
        {
            Series1.Add(new Data { Date = new DateTime(2012, 1, 1), Value = 1 });
            Series1.Add(new Data { Date = new DateTime(2012, 1, 3), Value = 4 });
            Series1.Add(new Data { Date = new DateTime(2012, 1, 5), Value = 9 });
            Series1.Add(new Data { Date = new DateTime(2012, 1, 7), Value = 16 });
 
            Series2.Add(new Data { Date = new DateTime(2012, 1, 2), Value = 4 });
            Series2.Add(new Data { Date = new DateTime(2012, 1, 4), Value = 2 });
            Series2.Add(new Data { Date = new DateTime(2012, 1, 6), Value = 1 });
 
            InitializeComponent();        
 
        }
 
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            xamDataChart.Series[0].DataContext = Series1;
            xamDataChart.Series[1].DataContext = Series2;
 
            xamDataChart.Axes[0].DataContext = Series1;
        }
    }

XAML:

<ig:XamDataChart HorizontalAlignment="Left" Name="xamDataChart" VerticalAlignment="Top" Height="445" Width="606" Margin="12,-4,0,0">
            <ig:XamDataChart.Series>
                <ig:LineSeries Title="L1"
                               XAxis="{Binding ElementName=xAxis}"
                               YAxis="{Binding ElementName=yAxis}"
                               ValueMemberPath="Value" Thickness="1"
                               ItemsSource="{Binding}"                               
                               MarkerType="Diamond"
                               />
                <ig:LineSeries Title="L2"
                               XAxis="{Binding ElementName=xAxis}"
                               YAxis="{Binding ElementName=yAxis}"
                               ValueMemberPath="Value" Thickness="1"
                               ItemsSource="{Binding}"
                               MarkerType="Circle"
                               />
            </ig:XamDataChart.Series>
            <ig:XamDataChart.Axes>
                <ig:CategoryDateTimeXAxis x:Name="xAxis" ItemsSource="{Binding}"
                                           Label="{}{0:dd.MM hh:mm}" DateTimeMemberPath="Date">
                    <ig:CategoryDateTimeXAxis.LabelSettings>
                        <ig:AxisLabelSettings Location="InsideBottom"></ig:AxisLabelSettings>
                    </ig:CategoryDateTimeXAxis.LabelSettings>
                </ig:CategoryDateTimeXAxis>
             
                <ig:NumericYAxis x:Name="yAxis">
                    <ig:NumericYAxis.LabelSettings>
                        <ig:AxisLabelSettings Location="OutsideLeft" Extent="50" VerticalAlignment="Center" Visibility="Visible" />
                    </ig:NumericYAxis.LabelSettings>
                </ig:NumericYAxis>
            </ig:XamDataChart.Axes>
        </ig:XamDataChart>

Only Series1 ist displayed. Is there a bug fix? Thanks in advance.
