Graphical Edit Gantt
Changes in the data are made by left clicking on the small red circles and and then at the desired new position. As the pointer moves to the new position, the Date/Days field shows a changing Date or number of days (task length) as appropriate.
WBS, Description, Organization, and Person fields for the current task (red highlighted WBS) can be made in the embedded dialog at the bottom of the chart. The current task is changed by left clicking on a task or using the < > buttons.
The WBS, ... fields can be expanded or contracted by moving the red circles on their end lines.
Other preference changes can be made in the preference dialog shown following the chart. (F4 brings up the Preference dialog for any display.)
Data changes are made only when the Schedule is recomputed.
