将鼠标悬停在DataPoint和ChangeBack上时将MarkerImage更改为何时离开Datapoint

Question

当用户在数据点上悬停时，我试图更改绘制数据点的标记图像。我的代码如下所示：

数据点在悬停在其上时一直在改变图像，但是没有将其改回“Red.png”？

任何人都可以找出为什么没有发生这种情况？

谢谢。

 Private Sub Chart1_MouseMove(ByVal sender As Object, ByVal e As MouseEventArgs) Handles Chart1.MouseMove
    Dim result As HitTestResult = Chart1.HitTest(e.X, e.Y)

    If result.ChartElementType = ChartElementType.DataPoint Then
        Chart1.Series(0).Points(result.PointIndex).MarkerImage = "Green.png"

    ElseIf result.ChartElementType = ChartElementType.PlottingArea Then
        Chart1.Series(0).MarkerImage = "Red.png"

    End If

End Sub

我想通了：改变这些线条

ElseIf result.ChartElementType = ChartElementType.PlottingArea Then
        Chart1.Series(0).MarkerImage = "Red.png"

至

ElseIf result.ChartElementType = ChartElementType.PlottingArea Then
            For i = 0 To Chart1.Series(0).Points.Count - 1
                Chart1.Series(0).Points(i).MarkerImage = "Red.png"
            Next

工作...
