how to auto-scroll axis x in a chart when using wpf ?

hi,  i'm using syncfusion chart to display a  polyline for  real-time.  i want to see the lastest 100 data in the chart and make the x axis scrolling automaticlly when receiving datas. how can i do it?

this is my xaml:

<syncfusion:SfChart Name="chart" Header="Demands Comparison" HorizontalAlignment="Center" Margin="10" VerticalAlignment="Center" Width="500" Height="300">         

            <syncfusion:SfChart.PrimaryAxis>

                <syncfusion:NumericalAxis  FontSize="10" Header="Primary Axis"  Minimum="0"  Maximum="100" ShowGridLines="True" />

            </syncfusion:SfChart.PrimaryAxis> 

            <syncfusion:SfChart.SecondaryAxis>

                <syncfusion:NumericalAxis FontSize="10" Header="Secondary Axis" Maximum="15000" Minimum="0"/>

            </syncfusion:SfChart.SecondaryAxis>

            <syncfusion:LineSeries Label="acc_x" ItemsSource="{Binding accdat}" XBindingPath="counts" YBindingPath="x" />

            <syncfusion:LineSeries Label="acc_y" ItemsSource="{Binding accdat}" XBindingPath="counts" YBindingPath="y" />

            <syncfusion:LineSeries Label="acc_z" ItemsSource="{Binding accdat}" XBindingPath="counts" YBindingPath="z"/>

            <syncfusion:SfChart.Legend>

                <syncfusion:ChartLegend/>

            </syncfusion:SfChart.Legend>

        </syncfusion:SfChart>

and C#:

    public class acc

    {

        public int x { get; set; }

        public int y { get; set; }

        public int z { get; set; }

        public int counts { get; set; }

    }

public ObservableCollection<acc> accdat { get; set; }

// in other thread 

this.chart.Dispatcher.Invoke

                        (

                            new Action

                                (

                                    delegate()

                                    {

                                        accdat.Add(new acc()

                                        {

                                            x = (data[2] << 8) | data[3],

                                            y = (data[4] << 8) | data[5],

                                            z = (data[6] << 8) | data[7],

                                            counts = c

                                        });

                                    }

                            )

                    );
