2. Type the following in a new module sheet:

         Sub CreateChart()
   
            ' Select the cell in the upper-left corner of the chart.
            Range("c4").Select
            ' Select the current range of data. This line of code assumes that
            ' the current region of cells is contiguous - without empty rows 
            ' or columns.
            Selection.CurrentRegion.Select
   
            ' Assign the address of the selected range of cells to a variable.
            myrange = Selection.Address
   
            ' Assign the name of the active sheet to a variable. This line is
            ' used in order to allow a chart to be created on a separate chart
            ' sheet.
            mysheetname = ActiveSheet.Name
   
            ' Add a chart to the active sheet.
            ActiveSheet.ChartObjects.Add(125.25, 60, 301.5, 155.25).Select
   
            ' To create a chart on a separate chart sheet, remark out the 
            ' previous line, and substitute the next line for the one above.
   
            ' Charts.Add
   
            Application.CutCopyMode = False
   
            ' This line can best be written by recording a macro, and 
            ' modifying the code generated by the Microsoft Excel Macro 
            ' recorder.
   
            ActiveChart.ChartWizard _ 
               Source:=Sheets(mysheetname).Range(myrange), _
               Gallery:=xlLine, Format:=4, PlotBy:=xlRows, _
               CategoryLabels:=1, SeriesLabels:=1, HasLegend:=1, _
