Multiple Bar Chart

In a multiple bars diagram two or more sets of inter-related data are represented (multiple bar diagram faciliates comparison between more than one phenomena). The technique of making a simple bar chart is used to draw this diagram but the difference is that we use different shades, colors, or dots to distinguish between different phenomena. We use to draw multiple bar charts if the total of different phenomena is meaningless.

 

Example:

Draw a multiple bar chart to represent the imports and exports of Canada (values in $) for the years 1991 to 1995.

Years	Imports	Exports
1991	7930	4260
1992	8850	5225
1993	9780	6150
1994	11720	7340
1995	12150	8145
