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 Blackboard, which automatically adds a variable node referencing that variable in the graph and connects it to the port of the node.
