Custom Expressions Introduction


The ability to create custom expressions is a powerful feature of TIBCO Spotfire. Custom expressions allow you to create your own aggregation methods for the visualizations.

The custom expression functionality can be accessed by right-clicking on the column selector in the visualization (or in the Visualization Properties dialog) and selecting the Custom Expression… option from the pop-up menu.
