[Adding animation to a bar chart]

I have just started using Chart FX for WPF and am trying to create an animation. However, I don't understand how I would reference the points in XAML.

For instance, when the chart is loaded, i want to animate the bars on a bar chart to move into position.

 

<ChartFX:Chart.Triggers>   <EventTrigger RoutedEvent="ChartFX:Chart.Loaded">   <BeginStoryboard>   <Storyboard>   <DoubleAnimationUsingKeyFrames  Storyboard.TargetName="mainChart" Storyboard.TargetProperty="AxisY">   <LinearDoubleKeyFrame KeyTime="0:0:0" Value="0" />   <LinearDoubleKeyFrame KeyTime="0:0:0.3" Value="1.2"/>   <LinearDoubleKeyFrame KeyTime="0:0:0.5" Value="0.8"/>   <LinearDoubleKeyFrame KeyTime="0:0:0.56" Value="1.0"/>   </DoubleAnimationUsingKeyFrames>   <DoubleAnimationUsingKeyFrames  Storyboard.TargetName="mainChart" Storyboard.TargetProperty="AxisY">   <LinearDoubleKeyFrame KeyTime="0:0:0" Value="0" />   <LinearDoubleKeyFrame KeyTime="0:0:0.3" Value="1.2"/>   <LinearDoubleKeyFrame KeyTime="0:0:0.5" Value="0.8"/>   <LinearDoubleKeyFrame KeyTime="0:0:0.56" Value="1.0"/>   </DoubleAnimationUsingKeyFrames>   </Storyboard>   </BeginStoryboard>   </EventTrigger>   </ChartFX:Chart.Triggers>

 

Obliviously, AxisY isnt a valid target property. Sorry if my explanation is vague. Any help would be appreciated.
