Hello Genvej,

I am just checking if you require any further assistance on the matter.

Here's a pretty simple example of using the motion framework. It assigns a different set of 50k values every time you click the refresh button and animates the change.
Note, there are various things you could do to make this sample more efficient, but I've tried to keep it as simple as possible. Let me know if you have any questions.
The xaml:

<Window.Resources>
        <local:TestData x:Key="data" />
    </Window.Resources>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition />
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        
        <igChart:XamDataChart x:Name="theChart">
            <igChart:XamDataChart.Axes>
                <igChart:NumericYAxis x:Name="yAxis" 
                                      MinimumValue="0"
                                      MaximumValue="300"/>
                <igChart:CategoryXAxis 
                    x:Name="xAxis"
                    ItemsSource="{StaticResource data}"
                    Label="{}{Label}"/>
            </igChart:XamDataChart.Axes>
            <igChart:XamDataChart.Series>
                <igChart:LineSeries
                    x:Name="series"
                    ItemsSource="{StaticResource data}"
                    XAxis="{Binding ElementName=xAxis}"
                    YAxis="{Binding ElementName=yAxis}"
                    MarkerType="None"
                    ValueMemberPath="Value"
                    TransitionDuration="0:00:01"/>
            </igChart:XamDataChart.Series>
        </igChart:XamDataChart>
        
        <Button x:Name="refresh" Content="Refresh" Click="refresh_Click" Grid.Row="1"></Button>
    </Grid>

And the code behind:

public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void refresh_Click(object sender, RoutedEventArgs e)
        {
            ((TestData)this.Resources["data"]).RefreshValues();
        }
    }

    public class TestData
        : ObservableCollection<TestDataItem>
    {
        private Random _rand = new Random();

        public TestData()
        {
            for (var i = 0; i < 50000; i++)
            {
                this.Add(new TestDataItem() { Label = i.ToString(), Value = 0 });
            }

            RefreshValues();
        }

        public void RefreshValues()
        {
            double curr = 150.0;

            for (var i = 0; i < Count; i++)
            {
                if (_rand.NextDouble() > .5)
                {
                    curr += _rand.NextDouble();
                }
                else
                {
                    curr -= _rand.NextDouble();
                }

                if (curr < 0)
                {
                    curr = 0;
                    curr += _rand.NextDouble();
                }

                if (curr > 300)
                {
                    curr = 300;
                    curr -= _rand.NextDouble();
                }

                this[i] = new TestDataItem() { Label = i.ToString(), Value = curr };
            }
        }
    }

    public class TestDataItem
    {
        public string Label { get; set; }
        public double Value { get; set; }
    }	

Hope this helps!

Also note, if you can provide me some information about how you are trying to use the motion framework I could put together a more purpose built sample that demonstrates a way of approaching your requirement.
