5.1.6.3 Multiple bars

In a multiple bar diagram two or more sets of interrelated data are represented. The technique of drawing such a diagram is the same as that of simple bar diagram. The only difference is that since more than one phenomenon is represented, different shades, dots or crosses are used to distinguish between the bars. Wherever a comparison between two or more related variables is to be made, multiple bar diagram may be preferred
