OxyPlot WPF - Get slected column

I am trying to get selected (clicked) column in OxyPlot WPF. Is there any way to do that? My WPF code so far:

<oxy:Plot x:Name="plotDiagram" Title="Output" >       
<oxy:Plot.Axes>
            <oxy:CategoryAxis ItemsSource="{Binding Item.barDisplayData1}" LabelField="DisplayText"/>
            <oxy:LinearAxis MinimumPadding="0" AbsoluteMinimum="0"/>
        </oxy:Plot.Axes>
        <oxy:Plot.Series>
            <oxy:ColumnSeries Title="{Binding Item.Title1}" FillColor="Green" IsStacked="True" ItemsSource="{Binding Item.barDisplayData1}" ValueField="Value" />
            <oxy:ColumnSeries Title="{Binding Item.Title2}" FillColor="Red" IsStacked="True" ItemsSource="{Binding Item.barDisplayData2}" ValueField="Value"/>
            <oxy:ColumnSeries Title="{Binding Item.Title3}" FillColor="Yellow" IsStacked="True" ItemsSource="{Binding Item.barDisplayData3}" ValueField="Value"/>
        </oxy:Plot.Series>
    </oxy:Plot>
