The 100% stacked column chart is similar to the stacked column chart, but it shows only the percentage distribution across categories. Each bar represents 100%, and the segments show the relative size of each sub-category.
This chart is especially helpful when comparing the composition of groups regardless of their absolute size. For instance, one could visualize the percentage of spending across cost categories (e.g., salaries, equipment, travel) for multiple departments. Even if one department has a much larger budget, this chart emphasizes the distribution rather than total volume.
