Multiple Bar Chart

By multiple bars diagram two or more sets of inter-related data are represented (multiple bar diagram facilities comparison between more than one phenomena). The technique of 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 import and export of Canada (values in $) for the years 1991 to 1995.
