Example 6.2: 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 6.1. Output 6.2.1 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 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 INCREMENT=5 specification indicates to the procedure
that labels are to be displayed in increments of 5 units of the
MININTERVAL= value,
which by default is DAY. 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 6.1.

* Overprint character when start or
finish times coincide
Symbols used for joining start and/or finish times
Symbol Explanation
- Duration of non-critical job
. Slack time for non-critical job
= Duration of critical job
- Slack time(neg.) for supercritical job
* Duration of supercritical job
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
