XL: Macro to Extract Data from a Chart

ID: Q137016

The information in this article applies to:

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.

The following sample macros will place the chart's source data in a worksheet called "ChartData" in the active workbook beginning in the first column and first row.

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.

Microsoft Excel version 5.0 or 7.0

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

      End Sub

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

3. Select or activate 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 GetChartVaules macro.

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