Profiles
A profile is a context in which an Arcade expression is evaluated and understood. They expect specific inputs and output types depending on the use case.
See below for a detailed explanation of the profiles and how they are used.
Alias
The alias profile allows the map author to write an expression to evaluate a numeric value and return a text alias representing that value.
When the alias is needed, the script will be evaluated. It will be passed the value for which an alias is desired. It is expected that the script returns a text value, comprising the alias to be shown.
Globals
| Variable Name | Type | Description |
|---|---|---|
| $value | Number | The numeric value for which a text alias is desired. |
Return types
Attribute Rules
The following profiles are designed for Attribute Rules.
Evaluation of batch calculation and validation rules is available at ArcGIS Enterprise 10.7 or later.
Attribute Rule Calculation
Since version: 1.5
With the Attribute Rule Calculation profile, expressions can be written to update field values based on expression logic. This profile is used for calculation attribute rules tools in ArcGIS Pro. When the attribute rule is evaluated for a dataset, the return value for the expression is cast to the field type of the output value. It is best practice to handle casting within the script for full control of casting behavior to Number, Date, or Text return types.
Globals
| Variable Name | Type | Description | Since version |
|---|---|---|---|
| $datastore | FeatureSetCollection | A collection of layers in the same feature service or database as the $feature executing the script. |
1.5 |
| $editcontext.editType | Text | Indicates whether the edit event is INSERT, UPDATE, DELETE, or NA (not applicable). |
1.10 |
| $feature | Feature | The feature being calculated. | 1.5 |
| $originalFeature | Feature | The previous state of the feature being calculated. | 1.9 |
| $featureSet | FeatureSet | A collection of features in the same table as the $feature evaluating the expression. |

Dashboard
The following profiles are designed for ArcGIS Dashboards.
Dashboard Formatting
Since version: 1.11
The Dashboard Formatting profile is used for the list and indicator elements in ArcGIS Dashboards. An expression can be written to customize the way elements render data points. It is expected that the script returns a dictionary of name-value pairs specific for the element.

Note: The dashboard formatting profile does not support FeatureSets and geometry functions.
Dashboard Data
Since version: 1.13
The Dashboard Data profile is used to create FeatureSets in ArcGIS Dashboards. Users can author data expressions to build FeatureSets that unlock insights and build robust visualizations. These expressions can be used as a data source for one or more data driven elements.
Note: This profile does not expose any global variables.
Return types
Dictionary Renderer
Since version: 1.11
The dictionary renderer profile allows the author of a dictionary renderer style to write an expression that evaluates to a text value used to construct a symbol. The string contains semi-colon separated style item keys as well as the primitive overrides used to override specific aspects of the symbol. See the Dictionary Renderer Toolkit for specifics on expected return values. When the feature is to be drawn, the script will be evaluated. The returned value will then be processed by looking up symbols by key from the dictionary and overriding them where specified.
Globals
| Variable Name | Type | Description |
|---|---|---|
| $feature | Feature | The feature which is to be drawn on the map. |
| $config | Dictionary | A dictionary of configuration values. |

Measure Visualization
Since version: 1.7
The measure visualization profile allows the map author to write an expression that evaluates to a value used to drive the visualization of measure values along a line. This is used in the context of linear referencing hatching of m-aware lines. When each measure value is drawn, the measure value is interpolated for the marker location and passed into the script. It is expected that the script returns the desired value to draw via a text graphic in a marker symbol.
Globals

Popup
Since version: 1.1
With the popup profile, map authors can write expressions that return values for display in the view's popup. Expressions can be referenced in the popup content's text template, field tables, and media charts. When the popup displays, the script will execute using the feature's attributes as variables in the expression. The script should return either text, a number, or date and place it in the table cell or text comprising the popup's content. Values returned for charts will be used as the basis for the data-driven chart.
Globals
| Variable Name | Type | Description |
|---|---|---|
| $feature | Feature | The feature whose popup is to be displayed in the view. |
| $layer | FeatureSet | A collection of features in the same layer as the $feature whose popup is displayed in the view. Only supported for feature service layers. |

Feature Z
Since version: 1.5
With the Feature Z profile, expressions can be written to calculate z values for features in a 3D scene. This is useful for features that don't have z values included in their geometry, or for dynamically changing the z value of features either using the former z value, attribute values, or a combination of both. Expressions in this profile must return a Number.
Globals
| Variable Name | Type | Description |
|---|---|---|
| $feature | Feature | The feature requiring a Z value. |
