XL: "Subscript Out of Range" Error When XValues Referenced

ID: Q139401

The information in this article applies to:

• Microsoft Excel for Windows, version 5.0
• Microsoft Excel for Windows 95, version 7.0

SYMPTOMS

When you reference values returned by the XValues property in a Microsoft Excel Visual Basic for Applications macro, you may receive the following error message:

   Run time error "9":
   Subscript out of range

CAUSE

This problem occurs because the XValues property returns a vertical array of x coordinates, which requires that you specify a second dimension for the array or transpose the array into a horizontal array.

RESOLUTION

To read the array of values returned by the Xvalues property, use either of the following methods.

Method 1

To reference the vertical array of values returned by the XValues property, use two-dimensional referencing. For example, reference the array (x) with 1 as the second dimension reference, as in the following macro:

   Sub DisplayXValues()
       Dim TheArray As Variant
       TheArray = ActiveChart.SeriesCollection(1).XValues
       For I = 1 To UBound(TheArray)
           MsgBox TheArray(I, 1)
       Next I
   End Sub

Method 2

Use the Transpose function to convert the two-dimensional array (vertical array) into a one-dimensional array (horizontal array). For example, transpose the array as in the following macro:

   Sub DisplayXValues()
      Dim TheArray As Variant
      TheArray = ActiveChart.SeriesCollection(1).XValues
      TheArray = Application.Transpose(TheArray)
      For I = 1 To UBound(TheArray)
         MsgBox TheArray(I)
      Next I
   End Sub
