Explainer

Data blending combines information from multiple independent data sources by querying them separately and displaying the results together in a visualization. To prevent duplicate rows and unmatched data, you must align the level of detail between your primary and secondary sources so that each mark in your view corresponds to a single matching value in the secondary source. Proper granularity alignment ensures accurate aggregation and reliable cross-source comparisons.

Core information
  • Data blending queries each data source independently, aggregates the results, and combines them visually on a sheet-by-sheet basis without creating a new unified data source.
More details and nuances
  • An asterisk appearing in a blended view indicates that the secondary source contains multiple values for a single mark in the primary source, signaling a granularity mismatch.
