Chapter 9 SECTOR CHARTS

A SECTOR chart presents data in the form of a circle. The circle is divided along its radii so that the angle of each section is proportional to the factual data it represents. Other terms used for sector chart are: pie chart, divided circle. In practically every instance in which material is presented in a sector chart, the same information might also be presented in bar charts. See Chapters 10 and 12.
