Multiple-Bar Diagram:
A limitation of a simple of a sub-divided bar diagram is that they can represent a single variable or single characteristic of the variable. If two or more sets of inter-related phenomenon or variables are to be presented graphically, multiple bar diagrams are used. In general, if the total magnitude of the multiple variables are additive, sub-divided bar diagram is used and if they are not additive in nature but they are related to each other they can be represented by multiple bar diagrams.

The technique of drawing such a chart is same as that of a single bar chart with the difference that each set of data is represented in different shades or colors on the same scale. An index explaining shades or colors must be given.

Example:
Represent the following data of agriculture production by multiple bar diagram.
