OxyPlot EventTrigger - wpf-controls

Question

I am trying to handle event in OxyPlot using EventTrigger. But it does not work like I want.
<Window x:Class="WpfApplication14.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
xmlns:oxy="http://oxyplot.org/wpf"
Title="MainWindow" Height="350" Width="525">
<Grid>
<oxy:PlotView Model="{Binding PlotModel}" DefaultTrackerTemplate="{x:Null}">
<i:Interaction.Triggers >
<i:EventTrigger EventName="MouseDown">
<i:InvokeCommandAction Command="{Binding Move}"></i:InvokeCommandAction>
</i:EventTrigger>
</i:Interaction.Triggers>
</oxy:PlotView>
</Grid>
And code look's like
using OxyPlot;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using OxyPlot.Axes;
using GalaSoft.MvvmLight.Command;
namespace WpfApplication14
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
///
public partial class MainWindow : Window
{
public class DataGeneration
{
public PlotModel PlotModel { get; set; }
public ICommand Move { get; set; }
public int _NumberOf;
public Dictionary<int, List<int>> Test { get; set; }
OxyPlot.Series.LineSeries LS;
Random rnd;
LinearAxis LA;
public int EndPosition = 0;
public DataGeneration(int NumberOf)
{
LA = new LinearAxis()
{
Position=AxisPosition.Bottom,
Minimum=0,
Maximum = EndPosition
};
Move = new RelayCommand(() => TestMove());
_NumberOf = NumberOf;
rnd = new Random();
Test = new Dictionary<int, List<int>>();
PlotModel = new PlotModel();
PlotModel.Axes.Add(LA);
LS = new OxyPlot.Series.LineSeries();
PlotModel.Series.Add(LS);
}
public void TestMove()
{
PlotModel.Axes[0].Reset();
}
public void AddPoint()
{
do
{
LS.Points.Add(new DataPoint(++_NumberOf, rnd.Next(1, 10)));
System.Threading.Thread.Sleep(1000);
EndPosition += 1;
LA.Maximum = EndPosition+3;
LA.Minimum = EndPosition;
Update();
} while (true);
}
public void Update()
{
PlotModel.InvalidatePlot(true);
}
}
public delegate void BeginUpdate();
private Stopwatch stopwatch = new Stopwatch();
private long lastUpdateMilliSeconds;
DataGeneration Data;
public MainWindow()
{
Data = new DataGeneration(1);
BeginUpdate BU = new BeginUpdate(Data.AddPoint);
IAsyncResult result = BU.BeginInvoke(null, null);
this.DataContext = Data;
CompositionTarget.Rendering += CompositionTargetRendering;
InitializeComponent();
}
private void CompositionTargetRendering(object sender, EventArgs e)
{
if (stopwatch.ElapsedMilliseconds > lastUpdateMilliSeconds + 300)
{
Data.Update();
}
}
}
}
why it firing when I make double click on OxyPlot? Genaraly i am trying to pan chart by left mousebutton.It's implemented in oxyplot by default(right mouse button).
