Silverlight Charting - Stacked Area vs Area Chart

Silverlight Charting - Stacked Area vs Area Chart

I am currently building a charting application in Silverlight 4.0, Visual Studio 2010. I currently have some area charts which are working fine, however I am currently trying to convert it to a stacked area chart and the libraries / properties for the stackedarea chart seem very different and it seems impossible to do data-binding to a stackarea chart. It simply does not find the property IndependentValueBinding or DependentValueBinding when using a stackedarea chart, so unless I hard-code in the values it seems there is no way of building this chart. Is there a workaround to this? The issue is highlighted clearer in the XAML below, where the area works fine and the stackedarea does not work at all.

        <ch:Chart x:Name="LineChart"                   Height="400"                   VerticalContentAlignment="Center">             <ch:Chart.Series>                 <ch:StackedAreaSeries Margin="0,0,20,20"                               Name="LineSeries"                               IndependentValueBinding = "{Binding Path=Key}"                               DependentValueBinding = "{Binding Path=Value}" />                 <ch:AreaSeries Margin="0,0,20,20"                               Name="LineSeries2"                               IndependentValueBinding = "{Binding Path=Key}"                               DependentValueBinding = "{Binding Path=Value}" />

Answer: 1

Define a seriesdefintion, which has all of the binding properties. Then add the series def to the stackedarea series.

Something like:

Dim StackedAreaSeries as StackedAreaSeries Dim SD as Seriesdefintion SD.independentvaluebinding = ... 

. define all series properties

Then

StackedAreaSeries.SeriesDefintions.add(SD)
