I am using chartingToolKit:Chart control. I want to remove the white space appear in between the chart and plot area. Attached the WPF sample and image of area to be removed.

<Window x:Class="WpfApplication2.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525" xmlns:chartingToolkit="clr-namespace:System.Windows.Controls.DataVisualization.Charting;assembly=System.Windows.Controls.DataVisualization.Toolkit">


<Grid>
    <chartingToolkit:Chart x:Name="chart" Width="500" Height="300" Margin="0, 0, 0, 0"   LegendStyle="{StaticResource LegendStyle}"   >


        <chartingToolkit:AreaSeries ItemsSource="{Binding}"  

                                   DependentValuePath="Value"

                                   IndependentValuePath="Key"

                                   Background="Red"

                                    >


        </chartingToolkit:AreaSeries>

        <chartingToolkit:Chart.Axes>
            <chartingToolkit:LinearAxis Orientation="X" ShowGridLines="False" Visibility="Hidden">

            </chartingToolkit:LinearAxis>
            <chartingToolkit:LinearAxis Orientation="Y" ShowGridLines="False" Visibility="Hidden"/>
        </chartingToolkit:Chart.Axes>

    </chartingToolkit:Chart>
</Grid>

The area marked in red arrow must be removed
