a
bar chart where each
bar representing a
quantity is made up of several
factors or
components. For
example, a
bar chart with
bars representing the total population of a country could have each
bar divided into
components that show the percentage of people in that country under 21 years of age, between 21 and 65, and over 65. The various age groups or
components in each
bar could be shaded differently for emphasis.
