Hello for the same type of my problem KingMartin has given the solution for me .That solution is as follows
CODE
Sub ChangeChartType()
Dim Sht As Worksheet
Dim Cht As ChartObject
For Each Sht In ThisWorkbook.Worksheets
For Each Cht In Sht.ChartObjects
Cht.Chart.ChartType = xlLine ' you can change any chart type here instead of X1Line
Next Cht
Next Sht
End Sub
--------------------------------------------------------------------------------
I hope you can adapt this to your requirements
Thanks To kingMartin
thanks to you
