SYMPTOMS

In Microsoft Visual Basic for Applications, you cannot add a new series to a chart in Microsoft Excel using an array as the Source argument with the Add method of the SeriesCollection object. If you specify the new data as an array of data points, you receive the following error message and your data points are not added to the chart:

   Run-time error '1004':
   Reference is not valid.

Method 1: Create a New Series From an Array

Although you cannot create a new series from an array in one statement, it is possible to use two steps to complete the task. The following is an example of using this two-step method:

   Sub Series()
       'Dimension variable x as Integer data type
       Dim x as Integer
       Sheets("Sheet1").Select
       ActiveSheet.ChartObjects(1).Select
       Selection.Chart.SeriesCollection.Add Source:=Range("A1")
       x = Selection.Chart.SeriesCollection.Count
       Selection.Chart.SeriesCollection(x).Values = Array(5, 6, 7)
   End Sub

Method 2: Use the Add Method

To add a new series to a chart in Microsoft Excel using the Add method of the SeriesCollection object, use a Range as the Source argument. For example, to add the range C1:C4 on Sheet1 as a new series to the active chart, use the following syntax:

   ActiveChart.SeriesCollection.Add _
       Source:=Sheets("Sheet1").Range("C1:C4")

MORE INFORMATION

The information in the Visual Basic Reference in Help incorrectly states that the source argument of the Add method (SeriesCollection) specifies the new data and can be either a Range or an array of data points. However, specifying an array of data points as a series with the Add method will produce the error stated above.
