Apply Layout (Network Diagram service)—REST APIs | Documentation for ArcGIS Enterprise

URL:https://<diagram-url>/applyLayout
Version Introduced: 10.6

Description

The applyLayout operation is performed on a Diagram resource. The result of this operation is a Diagram JSON Information object, and the moment (date) the applyLayout operation happens for a stored diagram.

It is used to apply a specific diagram algorithm on all or parts of the resource diagram content.

Dive-in:

Starting with ArcGIS Enterprise 10.7.1, the operation can be run as an asynchronous process—async=true. In this case, it uses the system UtilityNetworkTools geoprocessing service which is reserved for utility network geoprocessing tasks and has a longer default timeout setting.

License:

The active portal account must be licensed with the ArcGIS Advanced Editing user type extension to use this operation.

Request Parameters


Parameter	Details
gdbVersion	Description: The name of the geodatabase version. Syntax: gdbVersion=<version> Example: gdbVersion=ABV1
sessionId	Description: The token (guid) used to lock the version. Syntax: sessionId=<guid> Example: sessionId=44G259DE-87B0-407D-8F2E-DCB7665DD0F0
layoutName	Required Description: The name of the algorithm layout to apply (string) Syntax: layoutName = <AngleDirectedDiagramLayout \| CompressionDiagramLayout \| ForceDirectedDiagramLayout \| GeoPositionsDiagramLayout \| GridDiagramLayout \| LinearDispatchDiagramLayout \| MainLineTreeDiagramLayout \| MainRingDiagramLayout \| PartialOverlappingEdgesDiagramLayout \| RadialTreeDiagramLayout \| RelativeMainlineDiagramLayout \| ReshapeEdgesDiagramLayout \| RotateTreeDiagramLayout \| SeparateOverlappingEdgesDiagramLayout \| SmartTreeDiagramLayout \| SpatialDispatchDiagramLayout > Example: layoutName = ForceDirectedDiagramLayout
layoutParams	Description: The algorithm layout parameters property set. There is a specific property set JSON object for each diagram layout parameters Syntax: `layoutParams = { "type": "PropertySet", "propertySetItems": ["algoParamName1", <algoParamValue1>, …, "algoParamNameN",<algoParamValueN>] }` Example: Sample of parameter property set when layoutName = ForceDirectedDiagramLayout `layoutParams = { "type": "PropertySet", "propertySetItems": [ "are_containers_preserved", false, "is_active", false, "iterations_number", 20, "repel_factor", 1, "degree_freedom", 1 ] }`
junctionObjectIDs	Description: For the case you want the layout algorithm to apply to a diagram part, a list of junction ObjectIDs (long) that will be processed: Syntax: junctionObjectIDs=[<DiagJctOid1>, …, <DiagJctOidN] Example: junctionObjectIDs=[1,2,3,4,5]
containerObjectIDs	Description: For the case you want the layout algorithm to apply to a diagram part, a list of container ObjectIDs (long) that will be processed: Syntax: containerObjectIDs=[<DiagConOid1>, …, <DiagConOidN] Example: containerObjectIDs=[1]
edgeObjectIDs	Description: For the case you want the layout algorithm to apply to a diagram part, a list of edge ObjectIDs (long) that will be processed: Syntax: edgeObjectIDs=[<DiagEdgOid1>, …, <DiagEdgOidN] Example: edgeObjectIDs=[1,2,3]
async	Added in 10.7.1 Description: Specifies whether the layout algorithm will run synchronously or asynchronously (Boolean). false— The layout algorithm will run synchronously and can fail if the process completion exceeds the service timeout—600 seconds by default. This is the default. true— The layout algorithm will run asynchronously. This option dedicates server resources to run the layout algorithm with a longer time-out. Running asynchronously can be interesting when applying layout that are time consuming—for example, Partial Overlapping Edges—and applying to large diagrams—more than 25,000 features. Syntax: async=<true \| false> Example: async=true
f	Description: The response format. The default response format is html. Values: <html \| json>

Example Usage

Applying the SmartTree layout algorithm with its default parameters on the entire DiagramTest2 diagram resource content; this diagram being stored in version ABV1; that is:

URL: https://myserver.esri.com/server/rest/services/Naperville/NetworkDiagramServer/diagrams/DiagramTest2/applyLayout

Parameters:

gdbVersion=ABV1
sessionId=
layoutName=SmartTreeDiagramLayout
layoutParams=
junctionObjectIDs=
containerObjectIDs=
edgeObjectIDs=
async=
f=pjson

Sent URL (GET): https://myserver.esri.com/server/rest/services/Naperville/NetworkDiagramServer/diagrams/DiagramTest2/applyLayout?gdbVersion=ABV1&sessionId=&layoutName=SmartTreeDiagramLayout&layoutParams=&junctionObjectIDs=&containerObjectIDs=&edgeObjectIDs=&async=&f=pjson

JSON Response Syntax

A JSON object composed of a Diagram JSON Information object and a moment: {"diagramInfo": Diagram JSON Information, "moment": <moment>}

Note:

The moment is only returned for a stored diagram.
