XamDataChart with multiple series
posted

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.

    Hello Ansgar,

     

    Thank you for your post. I have been looking into it and I can say that collections you use as DataSources for the Series should have equal number of items. They could be null values and you can set the UnknownValuePlotting to DontPlot in order not to pot these values. Please let me know if this helps you or you need further assistance on this matter.

     

    Looking forward for your reply.
