Create an Organization Chart Using Open API

Organization chart is a useful tool for showing an organization’s structure, indicating its parts and positions’ relationships and ranks. This article will demonstrate how to create an organizational chart using Open API.

The organization chart will be created by the plugin.

Create a Blank Organizational Chart

We can first use the method DiagramManager.createDiagram to create a blank diagram.

//Create Blank Diagram
DiagramManager diagramManager = ApplicationManager.instance().getDiagramManager();
IDiagramUIModel org = (IDiagramUIModel) diagramManager.createDiagram(IDiagramTypeConstants.DIAGRAM_TYPE_ORGANIZATION_CHART);
org.setName("Simple Organization Chart");

Create Units

We can use IModelElementFactory to create units once the diagram is created.

//Create Unit
IOCUnit projectManager = IModelElementFactory.instance().createOCUnit();
projectManager.setName("Project Manager");
IOCUnitUIModel shapeProjectManager = (IOCUnitUIModel) diagramManager.createDiagramElement(org, projectManager);
shapeProjectManager.setBounds(400, 50, 150, 50);
shapeProjectManager.resetCaption();

For better categorization, you may use the method IOCUnitModel.getFillColor().setColor1(Color c) to customize the color of each block.

//Set up the color for the unit(Optional)
shapeSystemEng.getFillColor().setColor1(new Color(128, 128, 255));

Create Connectors

When all unit are created, we can then create the connector between them.

//create Connector
IOCLine proManToDeptMan = IModelElementFactory.instance().createOCLine();
proManToDeptMan.setFrom(projectManager);
proManToDeptMan.setTo(deptProjectManager);
diagramManager.createConnector(org, proManToDeptMan, shapeProjectManager, shapeDeptProjectManager, new Point[] {});

Show Up the Diagram

Finally, we can show up the diagram

//show up diagram
diagramManager.openDiagram(org);
