Star Charts

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 that is used to fill the star segments, and the color of chart text. You can generate groups of related star charts on a single page.
This chart 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.
