Create Diagram

Zusammenfassung

Creates a schematic diagram.

Depending on the schematic builder, diagram creation can be based on feature layers, feature classes, object tables, a network analysis layer, or XML data.

Verwendung

• If the output schematic diagram name already exists, it may be deleted before being re-created. To avoid this deletion, you can uncheck the Overwrite the outputs of geoprocessing operations box from the Geoprocessing Options dialog box.

• Depending on the schematic builder related to the diagram template specified for the diagram to be created, the Input Data parameter is required or not:

  • For a diagram template based on the Standard builder when it is configured to operate from a geometric network or a network dataset, the parameter is mandatory. The specified input tables may be feature layers, feature classes, or object tables.
  • For a diagram template based on the Network Dataset builder, a unique network analysis layer must be specified for the Input Data parameter.
  • For a diagram template based on the XML builder, a unique XML file must be specified for the Input Data parameter.
  • For a diagram template based on the Standard builder when it is configured to operate from custom queries, no input data is expected.

Syntax

CreateDiagram_schematics (out_location, out_name, diagram_type, {in_data}, {builder_options})

Parameter	Erläuterung	Datentyp
out_location	Schematic dataset or schematic folder in which the diagram will be created. Achtung: This container must already exist.	Schematic Dataset;Schematic Folder
out_name	Name of the schematic diagram to be created.	String
diagram_type [diagram_type,...]	Schematic diagram template of the schematic diagram to be created.	String
in_data [in_data,...] (optional)	The input data to generate the diagram. The Input Data parameter specifies the elements on which the diagram generation will be based. It must be specified for most of the predefined schematic builders: For diagram templates that work with the Standard builder configured to operate from a geometric network or network dataset, the Input Data parameter must at least reference a feature layer, feature class, or object table. For diagram templates that work with the Network Dataset builder, the Input Data parameter must reference a unique network analysis layer. If the related network analysis is not performed, Schematics tries to perform it before using the solved analysis layer as input. For diagram templates related to the XML builder, the Input Data parameter is optional when the data for the diagram generation is provided by an external component. But when no external component is defined for the builder properties, the Input Data must reference an XML file. In both cases, the input XML data must be built according to the XMLBuilderDiagram XML Schema file. For diagram templates that work with the Standard builder configured to operate from custom queries, no input data is required. Achtung: For diagram templates that work with the Standard builder when it is configured to operate from a geometric network or network dataset, XML builder, and Network Dataset builder, if no input data is specified, the diagram cannot be generated.	Table View;Data Element;Layer
builder_options (optional)	The schematic builder creation parameters. These parameters are required only for diagrams based on the Network Dataset builder to specify whether nodes will be merged. MERGE_NODES —Specifies the network element junctions, which are taken several times along the resultant route of a route analysis to be represented by a single schematic feature node in the generated schematic diagram. It also allows you to merge midspanjunction elements when they are at the same position in a service area analysis. NO_MERGE_NODES —Specifies that no schematic feature node will be merged (default).	String
