2.4.7.1.2.1 Summary Chart

The Summary Chart is shown in Figure 2-133. One of these
charts is produced for each period (hour or date) analyzed.
The date and hour being reported in each chart are printed in
the subtitle near the top of the chart.

The vertical axis of the chart shows the time intervals
during which analyses were done.  The horizontal axis
represents the number of tape drives allocated.

The vertical reference line represents a user-defined
exception limit.  Any interval during which the number of
tape drives allocated exceeds this limit is more fully
reported in the Summary Exception Report, described below.

The following table describes what type of workload the
symbols used in the Summary Chart represent:

SYMBOL USED   WORKLOAD REPRESENTED

    A         Workloads hypothetically added by the analyst.

    C         Actual work currently running at the time being
              reported.

    M         Actual workloads hypothetically moved to a
              different time interval by the analyst.
