Charts and diagrams

Many people find it easier to understand numerical
information if it is presented in a pictorial form, rather than
as a table of figures.

There are a number of simple charts and graphs commonly used to represent
business data.

3.1 Pie charts

Pie charts are a very easy way of depicting the percentage or proportional
breakdown of a total into various categories. They are so called because the total is
represented by a circle, with each component shown as a sector with area
proportional to percentage. Overall, the chart looks rather like a ‘pie’ with ‘slices’ in it.

Sometimes two pie charts are used to compare two totals, along with the manner in
which they are broken down. The sections, or slices, of the pie are proportional to the
total frequencies which aids comparisons between two charts.
