Unique
A unique value renderer symbolizes geoelements with a distinct symbol for each unique data value in an attribute. A unique value renderer contains a collection of UniqueValueRenderer.uniqueValues. Each UniqueValue has an UniqueValue.symbol and a collection of UniqueValue.values to define a value or combination of values.
This is typically used to visualize categories or data types. For example, you can use a unique value renderer to symbolize zoning designations: yellow for "Residential", purple for "Industrial", and green for both "Forests" and "Open land".
Since
200.1.0
Properties
The label used for the default symbol.
The default symbol for values that don't match any of the unique values.
A collection of the field names/attribute keys that the unique values apply to.
A collection of unique values used by the renderer to select a symbol.
Inherited properties
The expression describing how attributes values are translated into a rotation to be applied to the GeoElement. When an attribute name is specified in the rotation expression, it is enclosed in square brackets, for example: Rotation.
Indicates whether the rotation calculated from the Renderer.rotationExpression is interpreted as arithmetic or geographic. The options are:
The scene view properties for the renderer. This can be used to make changes to how a GeoElement is displayed in a SceneView.
Functions
Clones the UniqueValueRenderer.
Inherited functions
Returns the symbol that is used to visualize the given feature with override attributes from the renderer. If applyAttributeOverrides is set to true, this method will get the symbol from the renderer and override the symbol properties with the overrides available on the renderer. These include visual variable size, color, opacity and rotation. If the override expression or attributes contain any information not known to either the renderer or observation (such as "scale"), that override will not be applied. If the override attributes are applied successfully, a symbol with overridden properties will be returned otherwise the original symbol will be returned.
Returns the symbol that is used to visualize the given graphic with override attributes from the renderer. If applyAttributeOverrides is set to true, this method will get the symbol from the renderer and override the symbol properties with the overrides available on the renderer. These include visual variable size, color, opacity and rotation. If the override expression or attributes contain any information not known to either the renderer or observation (such as "scale"), that override will not be applied. If the override attributes are applied successfully, a symbol with overridden properties will be returned otherwise the original symbol will be returned.
Returns the symbol that is used to visualize the given dynamic entity with override attributes from the renderer. If applyAttributeOverrides is set to true, this method will get the symbol from the renderer and override the symbol properties with the overrides available on the renderer. These include visual variable size, color, opacity and rotation. If the override expression or attributes contain any information not known to either the renderer or dynamic entity (such as "scale"), that override will not be applied. If the override attributes are applied successfully, a symbol with overridden properties will be returned else the original symbol will be returned.
Returns the symbol that is used to visualize the given dynamic entity observation with override attributes from the renderer. If applyAttributeOverrides is set to true, this method will get the symbol from the renderer and override the symbol properties with the overrides available on the renderer. These include visual variable size, color, opacity and rotation. If the override expression or attributes contain any information not known to either the renderer or observation (such as "scale"), that override will not be applied. If the override attributes are applied successfully, a symbol with overridden properties will be returned else the original symbol will be returned.
