UML timing diagram
This UML timing diagram was created on the base of timing diagram example in the post "Determining Which UML Diagram to Use" from the Architexa blog.
"A project that contains many objects that frequently change state over a period of time would benefit from a Timing Diagram. Without a such a diagram you may not realize how potential periods of high traffic could intersect and overwhelm your program." [blog.architexa.com/2010/04/determining-which-uml-diagram-to-use/]
This UML timing diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the ATM UML Diagrams solution from the Software Development area of ConceptDraw Solution Park.
