Arcade in dashboards

ArcGIS Arcade is a portable, lightweight, and secure expression language. It can perform mathematical calculations, manipulate text, and evaluate logical statements. Arcade expressions can be authored in web maps for pop-ups, styles, and labels and are supported in the dashboard's map and details elements.

In a dashboard, you can take advantage of Arcade expressions in two additional ways. Data expressions can be used as the data source for a dashboard's data-driven elements. Formatting expressions can be used by the list, indicator, and table elements to provide fine-tuned control over their look within a dashboard.

Data expressions

Data-driven elements can use a data expression to create a feature set for use as a dashboard's data source. Data expressions can help prepare your data for use in a dashboard, and in turn, allow you to unlock new insights by combining, modeling, or enhancing the existing data.

Data expressions must return a FeatureSet. Data expressions use the Dashboard data Arcade profile.

Formatting expressions

You can use Arcade expressions for advanced formatting of the list, indicator, and table elements to customize how your data points render. A data point can represent either a feature or summary statistic based on how the element is configured. When using features, a single data point represents a single feature. When using a statistic, each data point represents the result of that statistic. Advanced formatting allows you to make visually compelling and informative elements for your dashboard.

Formatting expressions return a dictionary based on a key-value pair. Depending on the element, the set of dictionary keys are different. Advanced formatting uses the formatting profile for the specific element:
