Differentiate between multiple bar diagram and compound bar diagram.

Explanation

Multiple Bar Diagram: Multiple bar diagrams are constructed to represented two or more than two variables for the purpose of comparison. For example, we can draw two bars one indicating literacy rate of males and other literacy rate of fameles.
Compound Bar Diagram: When different components are grouped in one set of variables or different variables of one component are put together, their representation is made by a compound bar diagram. In this method, different variables are shown in a single bar with different rectangles. For example, total electricity produced in India is sub divided into hydro power, thermal power, nuclear power, etc.
