Methods and systems for displaying data retrieved from a multi-dimensional data source via an interactive data diagram. A graphical user interface is responsive to input from a user to retrieve multi-dimensional data for display via an interactive data diagram. The interactive data diagram displays multi-dimensional data in a hierarchical structure that includes a plurality of dimension levels and one or more member levels within each dimension level. A user specifies a change to the display structure by selecting a displayed member level in the hierarchical structure. The interactive data diagram is responsive to the user specified change to generate a drilled down data diagram displaying detailed dimension and member levels related to the selected member level.
