Expression Builder
Use expressions to filter the geospatial information displayed in your map, to create calculated
fields, and to change the styles used for a feature layer based on certain conditions.
Using the Expression Builder
The Expression Builder is displayed when you are doing the following:
■ Filtering the Layers You Add to a Map
■ Filtering Feature Layers
■ Filtering by Location
■ Searching to Select Feature Layers
■ Creating a Calculation
■ Using Expressions to Label Features
■ Using Expressions In Split/Merge Rules
Expressions you build with the Expression Builder affect geospatial data only
and cannot be used for drawing objects. For help with expressions that affect
drawing data, see the
Expression Evaluator (page 1541) section.
