UniqueValue Renderer
This renderer symbolizes features based on one or more matching string attributes.
Properties
| Property | Details |
|---|---|
| authoringInfo | An object containing metadata about the authoring process for creating a renderer object. This allows the authoring clients to save specific overridable settings so that next time it is accessed via the UI, their selections are remembered. Non-authoring clients can ignore it. |
| backgroundFillSymbol | A symbol used for polygon features as a background if the renderer uses point symbols, e.g. for bivariate types & size rendering. Only applicable to polygon layers. PictureFillSymbols can also be used outside of the Map Viewer for Size and Predominance and Size renderers. |
| defaultLabel | Default label for the default symbol used to draw unspecified values. |
| defaultSymbol | Symbol used when a value cannot be matched. |
| field1 | Attribute field renderer uses to match values. |
| field2 | If needed, specify an additional attribute field the renderer uses to match values. |
| field3 | If needed, specify an additional attribute field the renderer uses to match values. |
| fieldDelimiter | String inserted between the values if multiple attribute fields are specified. |
| legendOptions | A legend containing one title, which is a string describing the renderer in the legend. |
| rotationExpression | A constant value or an expression that derives the angle of rotation based on a feature attribute value. When an attribute name is specified, it's enclosed in square brackets. Rotation is set using a visual variable of type rotationInfo with a specified field or valueExpression property. |
| rotationType | String property which controls the origin and direction of rotation. If the rotationType is defined as arithmetic the symbol is rotated from East in a counter-clockwise direction where East is the 0 degree axis. If the rotationType is defined as geographic, the symbol is rotated from North in a clockwise direction where North is the 0 degree axis.If property is present, must be one of the following values:
|
| type | Specifies the type of renderer used. Value of this property must be uniqueValue |
| uniqueValueInfos | An array of uniqueValueInfo objects. |
| valueExpression | An Arcade expression evaluating to either a string or a number. |
| valueExpressionTitle | The title identifying and describing the associated Arcade expression as defined in the valueExpression property. |
| visualVariables | An array of objects used to set rendering properties. |
