Connect the nodes in a graph.
A wire is a line that connects the ports of two nodes in a graph.
This page covers how to connect nodes only. For information on how to implement a node, refer to Implement nodes for your graph tool. For information on node types and node anatomy, refer to About nodes.
To connect a node to another node that’s already on the graph, select the port of one node, and drag the mouse to the port of the other node.
A wire connects the nodes.
To connect a node to a node that doesn’t yet exist on the graph:
Identify the node you want to start with.
Use one of the following methods to create a new node:
The Add a graph node window opens.
Select the type of new node you want to connect.
The new node appears on the canvas. It connects to the starting node with a wire.
To add a variable node to an existing node, right-click a node’s port, and select Create Variable from port.
This creates a variable in the BlackboardA panel that displays and manages variables available for use in the graph. Users can create, edit, delete, organize variables and drag them directly onto the graph canvas for immediate use.
See in Glossary, which automatically adds a variable node referencing that variable in the graph and connects it to the port of the node.
