Diagram Page

Description:

The Diagrams view displays model elements and their references in a graphical way. This extension point is used to contribute diagrams displayed in this view.

Tip: Instead of creating a template by hand, you may add a new diagram template using the corresponding preference page (Window > Preferences and MDWorkbench > Models > Diagrams). This allows to select types and features using dedicated views and to quickly ensure the diagram definition looks correct on models. Then you just need to use the "Preview XML Declaration..." contextual menu on the diagram template preference, and to copy/paste the contents in a plugin.xml file.
