Diagram (element type)
Description
Diagram element represents a graph. It consists of nodes, edges and compartments (all of them are called as diagram elements). Node is usually represented as some geometrical shape like box or ellipse. Edge is a line which connects two nodes. Compartment is a special type of node which can contain other nodes inside.
When you double-click on the diagram in the repository tree, a diagram document is opened allowing you to view or edit the diagram. The only exception is the workflow diagrams: in BioUML web edition by default they are opened as analysis documents, where you can set the workflow parameters and launch it. Nevertheless you can edit a workflow if you use "Open diagram" context menu action.
There are numerous types of the diagrams. Some of them are listed here.
