Use the NodeFromPoint property to determine the node from specified position. If the X parameter is -1 and Y parameter is -1 the NodeFromPoint property determines the node from the cursor. Use the Caption property to specify the caption of the node. The control fires the Select event when the user clicks a node. 

The following VB sample prints the caption of the node from the cursor:

Private Sub ChartView1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With ChartView1
        Dim n As EXORGCHARTLibCtl.Node
        Set n = .NodeFromPoint(-1,-1)
        If Not (n Is Nothing) Then
            Debug.Print n.Caption
        End If
    End With
End Sub

The following C++ sample prints the caption of the node from the cursor:

void OnMouseMoveChartview1(short Button, short Shift, long X, long Y) 
{
	CNode node = m_chartview.GetNodeFromPoint( -1, -1 );
	if ( node.m_lpDispatch != NULL )
		OutputDebugString( node.GetCaption() );
}

The following VB.NET sample prints the caption of the node from the cursor:

Private Sub AxChartView1_MouseMoveEvent(ByVal sender As Object, ByVal e As AxEXORGCHARTLib._IChartViewEvents_MouseMoveEvent) Handles AxChartView1.MouseMoveEvent
    With AxChartView1
        Dim n As EXORGCHARTLib.Node = .get_NodeFromPoint(-1, -1)
        If Not (n Is Nothing) Then
            Debug.WriteLine(n.Caption)
        End If
    End With
End Sub

The following C# sample prints the caption of the node from the cursor:

private void axChartView1_MouseMoveEvent(object sender, AxEXORGCHARTLib._IChartViewEvents_MouseMoveEvent e)
{
	EXORGCHARTLib.Node node = axChartView1.get_NodeFromPoint(-1, -1);
	if (node != null)
		System.Diagnostics.Debug.WriteLine(node.Caption);
}

The following VFP sample prints the caption of the node from the cursor:

*** ActiveX Control Event ***
LPARAMETERS button, shift, x, y

With thisform.ChartView1
    local n
    n = .NodeFromPoint(-1 , -1 )
    If !isnull(n) Then
        wait window nowait n.Caption
    EndIf
EndWith
