Line chart with dynamically added series

* UPDATE: I've found the solution - you can ignore the question *

Hello,

I'm currently evaluating version 6.0.2165.22593 of Mindscape WPF Elements (the latest non-nightly version on the site). I'm trying to add line series to a chart by synchronizing my ObservableCollection to the chart object, as described here:

Dynamic Chart Series

With the example from the code supplied in that thread, it works great. X-values from 0 to 10 are created, and a random Y-value is assigned to that x.

Now, my series has custom objects. I have a TimeStamp-property (DateTime) that should be my x-value and a Value property (double) that is my y-value. I create the LineSeries in code, like this:

foreach (var dataSet in set)
            {
               LineSeries ds = new LineSeries();
               ds.ItemsSource = dataSet.Values;
               ds.SeriesBrush = Brushes.Green;
               var xBinding = new Binding("TimeStamp");
               xBinding.Source = dataSet.Values;
               ds.XBinding = xBinding;
               var yBinding = new Binding("Value");
               yBinding.Source = dataSet.Values;
               ds.YBinding = yBinding;
               ds.Title = dataSet.Tag.Name;
               TagSets.Add(ds);
            }

The ItemsSource property of the series object shows that it contains values. The problem is that I can't get the chart to show anything. The Y-axis sets the minimum and maximum values correctly (I think), but the X-axis never gets any values. Since the X-axis is a DateTime-axis, I tried setting the axis configuration like this:

<ms:Chart Background="White" x:Name="Chart" Title="Testdata" Margin="10" moduleClasses:CollectionBinder.SynchronizedSelectedItems="{Binding Data.TagSets}" LegendPosition="None" >
        <ms:Chart.XAxis>
            <ms:ChartAxis Title="Time" LabelFormat="{}{0:hh:mm tt}" ValueConverter="{StaticResource TimeScale}" Style="{StaticResource AxisStyle}" />
        </ms:Chart.XAxis>...

...and the resources:

<ResourceDictionary>
        <ms:DateTimeAxisValueConverter x:Key="TimeScale" />
        <DataTemplate x:Key="AxisLabelTemplate">
            <TextBlock Text="{Binding}" FontWeight="Normal" Foreground="{Binding Foreground, RelativeSource={RelativeSource AncestorType={x:Type ms:ChartAxis}}}" />
        </DataTemplate>

        <Style x:Key="AxisStyle" TargetType="{x:Type ms:ChartAxis}">
            <Setter Property="FontSize" Value="16" />
            <Setter Property="LabelTemplate" Value="{StaticResource AxisLabelTemplate}" />
            <Setter Property="FontWeight" Value="Bold" />
            <Setter Property="FontFamily" Value="Segoe UI" />
        </Style>...

I don't know where the problem lies. I'm out of ideas... could you point me in the right direction?

Best regards, Roland

Scratch this - I've found my error.

yBinding.Source = dataSet.Values;

You should not set the binding .Source. I guess it sets the collection as source, and tries to find the TimeStamp- and the Value-properties on the collection object instead of on each item in the collection. When I don't set the source it works.
