Overview

The Knowledge Graph control (XAML element TKnowledgeGraph) renders the UNS UserType hierarchy and per-Tag relationships as an interactive node-and-edge graph. Operators pan, zoom, and click nodes to inspect the underlying assets; node selections flow back into Tag-bindable properties so the rest of the Display can react to graph interaction.

...

• Naming history. The control was named TOntologyChart during the 10.1.5 preview period. The shipped name is TKnowledgeGraph; the old name was retired with no back-compatibility alias. Preview-period solutions persisting the old element type must re-add the control in the 10.1.5 Designer (see the Release Notes → Update 5 (Preview) Known Issues table).

• One source, many controls. Multiple Knowledge Graph controls on the same Display share the same source column — they all render the same graph. To show different views of the same ontology, post-process the source in a Script Task before placing it in the column.

• Companion features. Pairs with the Industrial Ontology Integration How-to import workflow and the LocalAI KnowledgeGraph Demo solution.
