2007 PPT Chart Data is not Reflecting In Chart

[littleiitin]

Hi,

I am Updating 2007 PPT Charts Data using Code in excel. Data files are kept in Separate Excel files.
Picking excel and updating chart. Data is in Charts Excel Sheet, However new Row or column is not reflecting in Chart.

Even Using Below Code I am Increasing the Size of Data Range, It is still not reflecting in chart. This Code I am using directly in PPT.

If I am doing Samething manually it starts Reflecting.

I am not able to use the setsourcedata Method too.

Sub Refresh()
    
    Dim chtObj      As Chart
    Dim wbkCht      As Object
    Dim wksCht      As Object
    Dim objPres     As Object
    Dim objSld      As Object
    Dim objShp      As Object
    
    Set objPres = ActivePresentation
    With objPres
        For Each objSld In .Slides
            For Each objShp In objSld.Shapes
                If objShp.Type = msoChart Then
                    Set chtObj = objShp.Chart
                    With objShp.Chart.ChartData
                        .Activate
                        .Workbook.Application.WindowState = -4140
                        Set wbkCht = .Workbook
                        Set wksCht = .Workbook.worksheets(1)
                        .Workbook.Application.WindowState = -4140
                        'objShp.Chart.SetSourceData wksCht.Range("A1").CurrentRegion                        wksCht.ListObjects("Table1").Resize wksCht.Range("A1").CurrentRegion.Resize(wksCht.Range("A1").CurrentRegion.Rows.Count - 1, wksCht.Range("A1").CurrentRegion.Columns.Count - 1)
                        wksCht.ListObjects("Table1").Resize wksCht.Range("A1").CurrentRegion
                    End With
                End If
            Next
        Next
    End With
    
End Sub

Thanks In advance
