Property Overview

Property Details

color Colorautocast

Autocasts from Number[]|String|Object

The color used to render dots representing the given field in a DotDensityRenderer or the color used to represent a pie chart slice in a PieChartRenderer.

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

field String

The name of the numeric attribute field represented by the given color.

label String

The label used to describe the field or attribute in the Legend widget.

valueExpression String

An Arcade expression following the specification defined by the Arcade Visualization Profile. Expressions in DotDensityRenderer may reference field values using the $feature profile variable and must return a number equal to the number of units represented by each dot. Expressions in PieChartRenderer must return a number representing the size of the pie chart slice.

This takes precedence over field. Therefore, this property is typically used as an alternative to field.
