US Patent 7944445 System and method for providing a dynamic expanded timeline

Generating a child timeline on a drawing sheet of a diagramming program such that the child timeline is dynamically linked to a parent timeline. An automated method allows for the automatic placing of information on the child timeline that was on the parent timeline when the child timeline is created. Parent and child timelines can be modified and a child timeline can be automatically updated when changes are made to the parent timeline and these changes affect the time interval corresponding to the child timeline.
