Sub-Divided Bar Graph/Diagram
In these diagrams, the bar corresponding to each phenomenon is divided into several components. Each part or component occupies a proportional part of the bar to its share in the total. For example, the bar corresponding to the number of students enrolled in a course can be further sub-divided into boys and girls.
- When preparing a sub-divided bar diagram, the various components in each bar should be kept in the same sequence.
- It is important to use different colours or shades to differentiate between different components.
- A suitable index should explain these various colours or shades.
- These diagrams are quite useful for comparing the sizes of various parts and throwing light on the relationship between these integral parts. For instance, such diagrams are used to present data such as sales profits from various products, a family’s expenditure pattern, the budget outlay for receipts and expenditures, and so on.
