Extend Excel chart datarange
 
The following macro can be used to extend the Excel chart range. The setDataRange can be used to set a new range but it seems impossible to retrieve the datarange. Therefore the code inspects the series and alters each series.
 
Public Sub chart_set_last_row()
    Dim cho As ChartObject
    Dim ser As Series
    Dim lngLastRow As Long
    Dim vntArr As Variant
     
    'Ask which row to set as last row'
    lngLastRow = Val(InputBox("Last row", "Set last row", 0))
     
    For Each cho In Selection
       For Each ser In cho.Chart.SeriesCollection
           vntArr = Split(ser.Formula, ",")
           If Not vntArr(1) = "" Then vntArr(1) = Left(vntArr(1), InStrRev(vntArr(1), "$")) & CStr(lngLastRow)
           vntArr(2) = Left(vntArr(2), InStrRev(vntArr(2), "$")) & CStr(lngLastRow)
           ser.Formula = vntArr(0) & "," & vntArr(1) & "," & vntArr(2) & "," & vntArr(3)
       Next ser
       cho.Chart.Axes(xlCategory).MinimumScaleIsAuto = True
       cho.Chart.Axes(xlCategory).MaximumScaleIsAuto = True
    Next cho
End Sub
