Aggregations Overview


Spotfire contains several visualizations and tools which calculate various aggregation measures or statistical measures. For a description of each measure, see the corresponding section.

Note: For measures where a large statistical selection is needed, the result from a calculation may vary with the number of available values.

In the column selectors of some visualizations there are also a number of aggregation measures available that are in fact shortcuts to expressions. See below for a description:

See Advanced Custom Expressions and Using Expressions on Aggregated Data (the THEN Keyword) for more general information about writing custom expressions with OVER and THEN.
