Hi Suri. THe totals for the items are stored as part of the grouping series (i..e, the ColumnSet, BarSet, etc) in an internal variable called totalsByPrimaryAxis. This variable is protected, so to access it you'll need to write a custom extension to the class. It's a dictionary, where the keys are values along the primary axis (the x axis for column/area, y axis for bar), and the values are the total at that point. If you look at ColumnSet.formatDataTip, you can see how the default data tips are calculated. So you'll want to extend the series to provide access to the item totals, and then use similar logic from that function for your own datatips. Ely.
