I've tried everything I can think of, but setting the Custom Property "Collected Tooltip" for a pie chart where there is data that will be "collected" into an "Other" slice doesn't appear to work. I am using SQL Server 2008 and SQL Server 2008 R2, and neither one seems to display the collected tooltip. I have no difficulty getting a tooltip to appear for all the other slices in the pie, using the series tooltip property. I've searched this forum as well as Google, and the only things I managed to find with any reference was one page that shows you where all those custom attributes are and how to use them. Is there a bug here, or am I doing something wrong? Steve
