Hello All,

I am using MVVM and I want to add a solid horizontal line at 0.0% YAxis, not fixed my YAxis values they are changed at run-time. My Xaml like this,

<ig:XamDataChart Name="chartResidual" BorderThickness="0" BorderBrush="Transparent" HorizontalZoomable="True">            
            <ig:SyncManager.SyncSettings>
                <ig:SyncSettings SyncChannel="syncGroup1"
                                            SynchronizeHorizontally="True"
                                            SynchronizeVertically="False" />
            </ig:SyncManager.SyncSettings>
            <ig:XamDataChart.Axes>
                <ig:CategoryXAxis x:Name="xAxis11"  ItemsSource="{Binding ChartSource}" MinorStroke="Transparent" MajorStroke="Transparent">                  
                    <ig:CategoryXAxis.Label>
                        <DataTemplate>
                            <StackPanel Orientation="Vertical">
                                <Border Background="Gray" Width="3" Height="5"/>
                                <TextBlock Text="{Binding Item.Date, StringFormat=MM/dd/yyyy}" HorizontalAlignment="Center" TextAlignment="Center">                                                    
                                                    <TextBlock.RenderTransform>                                                       
                                                    <TransformGroup>
                                                        <TransformGroup>
                                                        <RotateTransform Angle="30"/>
                                                        <TranslateTransform Y="3" X="33"/>
                                                    </TransformGroup>
                                                    </TransformGroup>
                                                </TextBlock.RenderTransform>
                                </TextBlock>
                            </StackPanel>
                        </DataTemplate>
                    </ig:CategoryXAxis.Label>

                </ig:CategoryXAxis>
                <ig:NumericYAxis x:Name="yAxis11"  MajorStroke="Gray"  MajorStrokeThickness="1.5" MajorStrokeDashArray="1 2">              
                    <ig:NumericYAxis.Label>
                        <DataTemplate>
                            <StackPanel Orientation="Horizontal" Margin="0">
                                <TextBlock Text="{Binding Item, StringFormat=P1}" Width="60" Foreground="Black" FontSize="11"></TextBlock>
                                <Border Background="Gray" Width="5" Height="3"/>
                            </StackPanel>
                        </DataTemplate>
                    </ig:NumericYAxis.Label>
                </ig:NumericYAxis>
            </ig:XamDataChart.Axes>
            <ig:XamDataChart.Series>
                <ig:LineSeries Thickness="2" MarkerType="None" ItemsSource="{Binding ChartSource}" ValueMemberPath="Value6"
                                            XAxis="{Binding ElementName=xAxis11}" YAxis="{Binding ElementName=yAxis11}" />
            </ig:XamDataChart.Series>
        </ig:XamDataChart>
