I am writing a program that uses Win32::OLE to plot an Excel chart of type xlXYScatterSmoothNoMarkers having multiple new series. For example, First series data should be from column A and B. And Second series data should be from Column C and Column D My problem is i am not able to get the source data dynamically. i.e Column A and B data can extend depending on the data. Examples in Using Win32::OLE and Excel were invaluable. Please help.

Sample Data.xls file
=======================
A    B    C     D
1    10   1     30
2    12   2     40
3    13   3     50
4    14   4     60
5    15   5     20
6    16   6     10
7    17
8    18

  Tried below Visual basic code, but not able to translate the same co
+de to perl 

    Range("A1").Select
    Range(Selection, Selection.End(xlDown)).Select
    data = Selection.Address(RowAbsolute:=False, ColumnAbsolute:=False
+)
    myRange = data & ","

   Range("C2").Select
    Range(Selection, Selection.End(xlDown)).Select
    GraphXSeries = Selection.Address(RowAbsolute:=False, ColumnAbsolut
+e:=False)
       
    Range("D2").Select
    Range(Selection, Selection.End(xlDown)).Select
    GraphValue = Selection.Address(RowAbsolute:=False, ColumnAbsolute:
+=False)
        
    Range("C1").Select
    GraphName = Selection.Address(RowAbsolute:=False, ColumnAbsolute:=
+False)
    
With SampleGraph
       
        .ChartType = xlXYScatterSmoothNoMarkers
        .SetSourceData Source:=Sheets(WorksheetName).Range(myRange), _
         PlotBy:=xlColumns
        .Location Where:=xlLocationAsObject, Name:=WorksheetName
        
        ActiveChart.SeriesCollection.NewSeries
        ActiveChart.SeriesCollection(2).Name = Worksheets(WorksheetNam
+e).Range(GraphName)
         
        ActiveChart.SeriesCollection(2).XValues = _
        Worksheets(WorksheetName).Range(GraphXSeries)
        
        ActiveChart.SeriesCollection(2).Values = _
        Worksheets(WorksheetName).Range(GraphValue)
