XL2000: Error Setting AxisGroup Property of Series Class

In Microsoft Excel 2000, if you run a Visual Basic for Applications macro that formats a chart, you may receive the following error message: Note that the same macro works correctly in versions of Microsoft Excel prior to Excel 97.

This problem occurs if both of the following conditions are true:

�	You are using a line of code similar to the following to move a series from the primary y axis to the secondary y axis: ActiveChart.SeriesCollection(3).AxisGroup = 2
�	Only one series in the chart is assigned to the primary y axis. For example, if a chart has three series, one of the series is assigned to the primary y axis. The other two series are assigned to the secondary y axis.

Note that it does not matter that the series you are moving is already assigned to the secondary y axis.

' Disable macro error messages.
On Error Resume Next

' Move the 3rd series to the secondary y axis.
ActiveChart.SeriesCollection(3).AxisGroup = 2

' Resume normal error handling.
On Error GoTo 0
				

NOTE: The "On Error" lines prevent the error from occurring.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

In versions prior to Excel 97, it is possible for all of the series in a chart to be assigned to the secondary y axis. In Microsoft Excel 2000, this is not possible. If you attempt to move the last series that uses the primary y axis to the secondary y axis, you receive an error message and the macro stops.

Because of a problem in the code that determines whether a series may be moved to the secondary y axis, you receive an error message even if the series in question is already assigned to the secondary y axis.
