Apply Layout (Network Diagram service)

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 UtilityNetworkToolsgeoprocessing service which is reserved for utility network geoprocessing tasks and has a longer default timeout setting.

License:
The ArcGIS Utility Network Management extension is required to use this operation.

Request Parameters

ParameterDetails
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 execute (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 execute on 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 execute on 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 execute on 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 its execution 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 executing 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.
