-------Thanks for the quick reply DBlank-------
This is what I'm currently doing using Chart Expert:
1) Use Chart-Type: 3D Raiser --> 3D bar chart
2) Select the "Data" Tab
3) Select "Layout" --> Advance
*On the "On Change of" field, I add 2-columns from my view.
*On the "Show Value(s)" I have 1 field that uses the SUM function.
The steps above don't result in the graph allowing users to drill-down into further details.
I'm not too sure what you mean by: "and then the chart has to use 'Group' as the Data tab type." -- are you refering to "Layout"
