Figure 3-9.  Sample Star Chart

Star, or Kiviat, charts represent multivariate data and are
not commonly used due to their complexity.  Each arm of the
star represents a unique value of the chart variable, while
the length of each arm represents the volume associated with
that variable.  For example, a star chart of average CPU time
per job class would have an arm for each unique job class and
the length of each arm would represent the average CPU time
per job for that job class.

You can set parameters to control chart labels and data
formats.

For color graphics, you can also control the color and
pattern used to fill the star segments, as well as the color
of chart text. You can generate groups of related star charts
on a single page.

Figure 3-9 is a sample star chart of program counts.  Each
segment represents a program; the width of each segment
represents the percent of program total executions, and the
length of each arm represents the number of program
executions.

To create a star chart, select the Star Chart option from any
of the following menus:
