SciChart: how to move a chart with RenderTransform?

Question

I am trying to move a vertical line that represents the time advance.

This is the code for this vertical line creation:

XAML:

<s:SciChartSurface.RenderableSeries>
   <s:FastLineRenderableSeries x:Name="lineSeries" SeriesColor="Red" />
   <s:FastLineRenderableSeries x:Name="verticalTimeLine"SeriesColor="Green"/>                                  
</s:SciChartSurface.RenderableSeries>

The line is initialized in the code behind as follows (C#):

var verticalLineTimeSeries = new XyDataSeries<float, float>();                
verticalLineTimeSeries.Append(0.0f, 0.0f);
verticalLineTimeSeries.Append(0.0f, 10.0f);
verticalTimeLine.DataSeries = verticalLineTimeSeries;

And this is the code where i've made a test with RenderTransform to move the timeline:

TranslateTransform translateTransform = new TranslateTransform();
translateTransform.X = 400;
translateTransform.Y = 0;
verticalTimeLine.RenderTransform = translateTransform;            
verticalTimeLine.UpdateLayout();

The problem is that the line does not move at all. What am i doing wrong? Thanks in advance.

Well, finally i've been able to resolve my problem by using Annotations. I'm going to post the code in case that someone has a similar problem

First on the Xaml part:

On UserControl Resources we set a simple style, green color and thicknes value 2:

<UserControl.Resources>

    <Style x:Key="AnnotationStyle"TargetType=" s:VerticalLineAnnotation">                        
        <Setter Property="Stroke">
            <Setter.Value>                        
                <SolidColorBrush Color="Green"/>
            </Setter.Value>
        </Setter>               
        <Setter Property="StrokeThickness" Value="2"/>                
    </Style>

</UserControl.Resources>

The annotations:

<s:SciChartSurface.Annotations>
    <s:VerticalLineAnnotation X1="0" x:Name="annotation" Style="{StaticResource AnnotationStyle}" />
</s:SciChartSurface.Annotations>

And this is the code behind to test its movement:

annotation.X1 = 5.5;
