Bar charts or bar graphs are suitable for displaying long data labels. Column charts have limited space in the category axis. So, when your data labels are long, the category axis may look cluttered. However, using the bar diagram will significantly improve the readability of your chart. Bar graphs are good for displaying a large number of data sets on the category axis. A bar graph with the data sets placed one below the other would be a better choice in this case as it makes optimum use of space.
