SUMMARY

In Microsoft Excel, you can retrieve data from a chart even when the data is in an external worksheet or workbook. This is useful in situations where the chart was created from, or linked to, another file that is unavailable or has been damaged in some way. When the source data to a chart is lost, the data can still be retrieved from the chart itself using a Microsoft Visual Basic for Applications macro.

Excel 97 for Windows and Excel 98 Macintosh Edition

1. Enter the following macro code in a module sheet:

         Sub GetChartVaules97()
            Dim NumberOfRows As Integer
            Dim X As Object
            Counter = 2
   
            ' Calculate the number of rows of data.
            NumberOfRows = UBound(ActiveChart.SeriesCollection(1).Values)
   
            Worksheets("ChartData").Cells(1, 1) = "X Values"
   
            ' Write x-axis values to worksheet.
            With Worksheets("ChartData")
               .Range(.Cells(2, 1), _
               .Cells(NumberOfRows + 1, 1)) = _  
               Application.Transpose(ActiveChart.SeriesCollection(1).XValues)
            End With
   
            ' Loop through all series in the chart and write their values to       
            ' the worksheet.
            For Each X In ActiveChart.SeriesCollection
               Worksheets("ChartData").Cells(1, Counter) = X.Name
   
               With Worksheets("ChartData")
                  .Range(.Cells(2, Counter), _
                  .Cells(NumberOfRows + 1, Counter)) = _
                  Application.Transpose(X.Values)
               End With
   
               Counter = Counter + 1
            Next
   
         End Sub
   
   

2. Insert a new worksheet into your workbook and rename it to "ChartData" (without the quotation marks).

3. Select the chart from which you want to extract the underlying data values.

   NOTE: The chart can either be embedded on a worksheet or on a separate chart sheet.

4. Run the GetChartVaules97 macro.

   The data from the chart will be placed in the "ChartData" worksheet.

1. Enter the following macro code in a module sheet:

         Sub GetChartVaules()
            Dim NumberOfRows As Integer
            Dim X As Object
            Counter = 2
   
            ' Calculate the number of rows of data.
            NumberOfRows = UBound(ActiveChart.SeriesCollection(1).Values)
   
            Worksheets("ChartData").Cells(1, 1) = "X Values"
   
            ' Write x-axis values to worksheet.
            With Worksheets("ChartData")
               .Range(.Cells(2, 1), .Cells(NumberOfRows + 1, 1)) _
               = ActiveChart.SeriesCollection(1).XValues
            End With
   
            ' Loop through all series in the chart and write their values to 
            ' the worksheet.
            For Each X In ActiveChart.SeriesCollection
               Worksheets("ChartData").Cells(1, Counter) = X.Name
   
               With Worksheets("ChartData")
                .Range(.Cells(2, Counter), _
                .Cells(NumberOfRows + 1, Counter)) = X.Values
               End With
   
               Counter = Counter + 1
            Next
