Component Bar Chart

Sub-divided or component bar cha t is used to represent data in which the total magnitude is divided into different or components.

In this diagram, first we make simple bars for each class taking total magnitude in that class and then divide these simple bars into parts in the ratio of various components. This type of diagram shows the variation in different components within each class as well as between different classes. Sub-divided bar diagram is also known as component bar chart or staked chart.

Example:

The table below shows the quantity in hundred kgs of Wheat, Barley and Oats produced on a certain form during the years 1991 to 1994.

Construct a component bar chart to illustrate this data.

Solution:

To make the component bar chart, first of all we have to take year wise total production.
