A grouped bar chart, also known as clustered bar graph, multi-set bar chart, or grouped column chart, is used to compare different categories of two or more groups. Because categories are grouped and arranged side-by-side, the bar clusters make easy to interpret the differences inside a group, and even between the same category across groups.
Create a horizontally or vertically plotted grouped bar chart, in which each category has its particular color. If you add further categories or groups, these will be automatically arranged in your graph. Groups are labeled, and you can display categories and their colors as a legend. For a cleaner layout, hide the grid and the value axis.
PS: If there is a part-to-the whole relationship or if you want to emphasize the comparison among the total sum of the groups, consider creating a stacked bar chart.
