Properties

Property	Details
aggregationLayer	Represents a aggregated link chart sub layer object that contains aggregated entities or relationships specific to graphTypeName for this link chart sub layer.
blendMode	Blend modes are used to create various effects by blending colors of top and background layers. normal blend mode is the default. Valid values: average, color, color-burn, color-dodge, darken, destination-atop, destination-in, destination-out, destination-over, difference, exclusion, hard-light, hue, invert, lighten, lighter, luminosity, minus, multiply, normal, overlay, plus, reflect, saturation, screen, soft-light, source-atop, source-in, source-out, vivid-light, xor
charts[]	An array of chart items of type WebChart available on the link chart sub layer.
disablePopup	Indicates whether to allow a client to ignore popups defined by the service item.
displayExpressionInfo	Object defining Arcade expression that will return a display name used for listing entities or relationships. This Arcade expression profile expects the returnType to be always a string.
effect	Effect provides various filter functions to achieve different visual effects similar to how image filters (photo apps) work.
featureEffect	Feature Effect emphasizes or deemphasizes features that satisfy a filter using graphical effects
graphType	Indicates the type of graph object. Valid values: entity relationship
graphTypeName	Represents a unique identifier for a knowledge graph entity or relationship. If graphTypeName represents entity, features can be fetched from the featureset persisted as pbf specified as entitiesUrl in the parent's link chart properties and relationships from relationshipsUrl.
id	A unique identifying string for the layer.
layerDefinition	A layerDefinition object defining the attribute schema and drawing information for the layer. See layerDefinition properties table.
layerType	String indicating the layer type. Valid value of this property LinkChartSubLayer
opacity	The degree of transparency applied to the layer on the client side, where 0 is full transparency and 1 is no transparency.
popupInfo	A popupInfo object defining the content of popup window when you click a feature on the map.
refreshInterval	Refresh interval of the layer in minutes. Non-zero value indicates automatic layer refresh at the specified interval. Value of 0 indicates auto refresh is not enabled.
showLabels	Labels will display if this property is set to true and the layer also has a labelingInfo property associated with it. This property can get stored in the web map config and in the item/data.
showLegend	Boolean value indicating whether to display the layer in the legend. Default value is true.
timeAnimation	Indicates whether to disable time animation if the layer supports it.
title	A user-friendly string title for the layer that can be used in a table of contents.
visibility	Boolean property determining whether the layer is initially visible in the web map.

layerDefinition properties

Property	Details
definitionExpression	SQL-based definition expression string that narrows the data to be displayed in the layer.
drawingInfo	Contains the drawing and labeling information.
featureReduction	An object defining how to aggregate dense data to clusters or bins. This is a visualization-only feature intended solely for reducing the visual complexity of many overlapping features to a few aggregate features that communicate patterns of density. This is not intended to be used for analytical purposes.
maxScale	Integer property used to determine the maximum scale at which the layer is displayed.
minScale	Integer property used to determine the minimum scale at which the layer is displayed.
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.
timeInfo	An object that defines properties to enable time on a layer or table. Refer to the individual layerDefinition properties to see which layer types support this.
