A system and a method are disclosed for visually displaying data points using pie charts on a display screen with limited display area. Detailed information is presented for individual sectors compared to other sectors displayed. The sector is selected for displaying detailed information based on its orientation with respect to a centerline axis of the chart. The pie chart can be rotated to cause detailed information to be displayed for different sectors. The mechanism is used to display detailed information of data points for other kinds of charts including multi-series pie charts and donut charts.

A system generates linked sets of drill-down-enabled reports of increasing levels of detail from one or more databases. Linking relationships between reports are defined using the query language of the databases. Result sets are obtained that includes (1) the sought-after data, and (2) metadata that identifies drill-down reports to be generated if related report elements are selected. When the query is executed, the system passes the sought-after data to a reporting application programming interface, which generates a report (e.g., a pie chart, 3-D bar chart, cross-tabbed table). If an end-user selects one of the report elements (e.g., a bar on the chart), the system maps the reported event to the associated data of the result set. If the associated data has corresponding meta-data containing a drill-down directive, the system then generates the report identified by the drill-down directive.
