A component bar chart is the chart in which one bar of the chart shows the distribution of all of the components. For example, if you want to allocate the number of men and women in a region in different years then for the year 2000 the bar will show two parts in two different color. The base of the bar may show the number of men and the above part of the bar may show the number of women. For diagram click on the link:
