A computer graphics system is presented which can be used by project managers and planners to display the project activities and the logical order of the activities on a time-scaled bar chart. The system called a fenced bar chart clearly displays the critical path and the path float on each of the other paths and emphasizes the logic order of, as well as when, the activities should be accomplished. Since the display is computerized, the development of alternative plans or the tracking of and control of an actual project is easily and quickly produced. The display of limited resources schedules is also very useful.
