<dxc:Chart3DControl x:Name="chartControl">
    <dxc:Chart3DControl.ContentTransform>
        <Transform3DGroup>
            <Transform3DGroup.Children>
                <RotateTransform3D>

The following code applies the same transformations as the markup above but at runtime:

C#

using System.Windows.Media.Media3D;
//...
private void chartControl_Loaded(object sender, RoutedEventArgs e) {
    chartControl.ContentTransform = GetContentTransformation();
}

Transform3D GetContentTransformation() {
    Transform3DGroup transform = new Transform3DGroup();
    transform.Children.Add(new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(1, 0, 0), 30)));
    transform.Children.Add(new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 1, 0), 20)));
    transform.Children.Add(new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 0, 1), 10)));
    transform.Children.Add(new ScaleTransform3D { ScaleX = 1.5, ScaleY = 0.8, ScaleZ = 1,
                                                  CenterX = 0, CenterY = 0, CenterZ = 0 });
    transform.Children.Add(new TranslateTransform3D { OffsetX = 20, OffsetY = 30, OffsetZ = 80 });
    return transform;
}

VB.NET

Private Sub chartControl_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
    chartControl.ContentTransform = GetContentTransformation()
End Sub

Private Function GetContentTransformation() As Transform3D
    Dim transform As Transform3DGroup = New Transform3DGroup()
    transform.Children.Add(New RotateTransform3D(New AxisAngleRotation3D(New Vector3D(1, 0, 0), 30)))
    transform.Children.Add(New RotateTransform3D(New AxisAngleRotation3D(New Vector3D(0, 1, 0), 20)))
    transform.Children.Add(New RotateTransform3D(New AxisAngleRotation3D(New Vector3D(0, 0, 1), 10)))
    transform.Children.Add(New ScaleTransform3D With {
        .ScaleX = 1.5,
        .ScaleY = 0.8,
        .ScaleZ = 1,
        .CenterX = 0,
        .CenterY = 0,
        .CenterZ = 0
    })
    transform.Children.Add(New TranslateTransform3D With {
        .OffsetX = 20,
        .OffsetY = 30,
        .OffsetZ = 80
    })
    Return transform
End Function
