What Is a Gantt Chart?

A Gantt chart is a type of time-based graph that displays stacked bars to illustrate project schedules and dependencies. ClosedExample

Gantt chart example.

To generate this type of time graph, your cBase or model must have data components similar to the following:

  • A Task dimension that contains a list of task names
  • Two summaries: Task Start and Task End (dates or numbers)

The following optional components are often included:

  • Dependency Info Field—Lists a task that must be completed before this task can begin. Dependency relationships appear on the graph as vertical lines that connect a task end time with its dependent task start time.
  • Legend Info Field—Defines labels that appear on the legend. When defined, tasks related to the info field are color-coded on the graph. Tasks that are not associated with a category appear gray. In the above Closedexample, the graph shows when team resources need to be available, which enables a program manager to plan accordingly.
