Example 8.2 Customizing the Gantt Chart
This example shows how to control the format of the Gantt chart using CHART statement options. The Schedule data set used by PROC GANTT is the same as that used in Example 8.1. Output 8.2.1 is on three pages; the first page contains a detailed description of the various symbols used by the procedure to plot the schedule. This description is produced by using the SUMMARY option. The next two pages contain the Gantt chart. The LINEPRINTER option invokes the procedure in line-printer mode. The FILL option causes the first page to be filled as completely as possible before the second page is started. Thus, the first page of the chart contains 20 activities while the second page contains only 8 activities.
The MININTERVAL=WEEK specification defines the units of time for axis labeling. The SCALE=5 specification causes five columns of the chart to be used to display one week. The SKIP=2 specification causes two lines to be skipped between observations. The NOLEGEND option suppresses displaying of the legend, while the NOJOBNUM option causes job numbers to be omitted. The CRITFLAG option is used to produce the flag to the left of the main chart indicating if an activity is critical. Specifying BETWEEN=2 sets the number of columns between consecutive ID columns equal to 2. The REF= option produces the reference lines shown on the chart on the specified dates. The ID statement is used to display the activity names to the left of the chart. The ID statement also causes the activity 'strip' to appear only once in the chart. Thus, there are only 28 activities in this chart instead of 29, as in Example 8.1.

Some examples of typical strings
String Description
<--->...<...> Duration followed by slack time:
early finish before late start
<---<--->...> Duration followed by slack time:
early finish after late start
<---*...> Duration followed by slack time:
early finish equals late start
*===* Duration of job on critical path
<--->---<***> Duration preceded by negative slack
time for a supercritical job:
late finish before early start
<---<***>***> Duration preceded by negative slack
time for a supercritical job:
late finish after early start
<---****> Duration preceded by negative slack
time for a supercritical job:
late finish equals early start
