We are binding a BrushCollection to the XamDataChart as shown:

<ig:XamDataChart Legend="{Binding ElementName=XmLegend}" Brushes="{Binding MyBrushes}">

and then creating our own LegendTemplate for the column series as shown:

DataTemplate x:Key="LegendTemplate">
                        <Border Visibility="{Binding Series.Visibility}">
                            <StackPanel Orientation="Horizontal">
                                <Rectangle 
                                    Fill="{Binding Series.Brush}"
                                    Width="10" Height="10" 
                                    Margin="2"/>
                                <ContentPresenter Content="{Binding Series.Title, TargetNullValue=Series Title}" Margin="2" ></ContentPresenter>
                            </StackPanel>
                        </Border>
                    </DataTemplate>

but  Fill="{Binding Series.Brush}" does not seem to pick up the binded brush collection.  We can see this work if the Brushes are assigned to each individual column series, but the legend does not display colors when a collection is bounded to the data charts  "Brushes" attribute.

Is there another attribute we can tap into in order to leverage the binded BrushCollection for our custom legend template?
