Gantt chart reference

A Gantt Chart is a horizontal bar chart that graphically displays activities over time and the possible relationships between the activities.

In IBM® Rational® Focal Point™, the Gantt chart view consists of five areas:

The Gantt area
Displays the elements in the view, the date attributes and relationships between elements.
The Stacked value area
Displays the sum of each value over time. For example, this area might display the sum of the development cost and production cost for all of the projects in the Gantt area.
The Time scale area
Displays the elements position and the stacked values over time
The Selections area
Displays the date in the Gantt area, decides what kind of links to display in the Gantt area and what integer or float attributes to display in the stacked value area.
The Grouping area
Groups the elements according to a specific attribute

To display the elements, click Display. In a Gantt chart, each element is displayed as a bar that consists of a number of boxes, each of which is separated by a Date icon. Links between elements are represented by colors.

Known Limitations
  • An "Out of memory" error might occur while viewing larger Gantt charts. Use smaller views to avoid this problem.
  • In IBM Rational Focal Point version 5.3 and later, you can display up to 75 elements in a Gantt chart. To increase or decrease this number, an administrator must run some SQL commands. Element titles that are larger than 40 characters are truncated. For more information, contact IBM Rational Software Support.
