A stacked bar chart displays a part-to-whole relationship among categories within various groups. The columns representing the groups are therefore divided into smaller segments, making the proportions and relationship of the categories to each group explicit. Because the bars visually aggregate all categories, this graph is ideal for highlighting sharp differences of composition, and, more particularly, to compare the total values across the groups.

Pro tip: If there is no part-to-the whole relationship or if you want to emphasize the comparison of the individual categories, consider creating a grouped bar chart.
