| Property | Details |
|---|---|
| drawingInfo.labelingInfo[] | An object defining the properties used for labeling the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| drawingInfo.renderer | An object defined which provides the symbology for the layer. If working with Map Image layers, this property is only applicable if the layer is enabled with dynamic layers |
| orderBy[] | An array of orderByField objects specifying the feature display order. Features can be sorted in ascending or descending order of a numeric or date field only. If ascending, features with smaller values will be drawn on top of features with larger values. For date values, ascending order means features with older dates will be drawn on top of features with recent dates. If descending, the sort behavior is reversed. When this property is not defined, features are displayed in the order in which they are received by the client. |
