Example 4.5 Precedence Gantt Chart
This example produces a Gantt chart of the schedule obtained from PROC CPM. The example uses the network described in Example 4.2 (AOA format) and assumes that the data set SAVE contains the schedule produced by PROC CPM and sorted by the variable E_START. The Gantt chart produced shows the early and late start schedules as well as the precedence relationships between the activities. The precedence information is conveyed to PROC GANTT through the TAILNODE= and HEADNODE= options.
