What is a grouped bar chart?

A grouped bar chart, also known as clustered bar graph, multi-set bar chart, or grouped column chart, is a type of bar graph that is used to represent and compare different categories of two or more groups.

Because the 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.

Best uses for the grouped bar chart

• Showing the changes in set categories over time, location or sector
• Comparing financial data–for example sales, costs and revenue–across different groups
• Evaluating the performance of a series of marketing projects in contrast to one another

Grouped bar chart: pro tips

• 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.
• Color coding is essential with this chart, so make sure the shades you use are easily distinct from one another and clearly labelled in the legend
• Long category names often work better with a horizontal bar chart, alternatively, you can click the layout–switch easily with the check box on the “APPEARANCE” tab
• One huge value number can dwarf the rest of the bars, so try using the “Scale break” function to re-balance the visuals (but only use this if absolutely necessary, as it can make your chart appear misleading)
• On the “APPEARANCE” tab, you can select the “Custom group width” checkbox to edit the design of your chart further
