I have an application that uses three data series. One to display the actual
data (x and y values) in a column format and the other two to show "average"
values for the whole company (taken from a field on another tab) and for the
current data. The actual data it's average is held in a pivot table but the
series data is set from VB (the chart is not a pivotchart). In the pivot
table change event the data series values are refreshed by looping around the
cells covered by the table. The two average lines show but the data values
disappear. This worked fine in Excel2003.

Thanks
