Level of Detail Calculation Generation for Data Visualizations

The system automatically generates Level of Detail expressions by analyzing user selections of data fields and visualization parameters. The computer identifies required aggregations and creates the appropriate LOD expressions without manual user input, allowing the system to serve itself in generating the complex computational logic needed for accurate data aggregation.

The patent replaces the manual mechanical process of writing and managing LOD expressions with an automated computational system. The computer analyzes data field relationships and automatically generates the computational expressions, substituting human cognitive effort with algorithmic processing that accurately handles the complexity of multi-level data aggregation.

The system segments the data aggregation process into distinct levels by identifying different data fields and their hierarchical relationships. Each data field can be associated with a specific aggregation level, allowing the system to handle multiple granularity levels independently. This segmentation enables flexible multi-level aggregation without requiring the user to manage the entire aggregation hierarchy as a single complex structure.

The patent introduces a new dimension of aggregation level as a separate attribute that can be independently controlled for different data fields. Instead of managing complexity through nested hierarchical structures, the system adds an aggregation level dimension that allows fields to be positioned at different levels simultaneously, simplifying the interface while supporting versatile multi-level analysis.
