Use a percentage component chart whenever you want to show how the shares of something or percentages vary across a number of different cases or areas.
Don’t use percentage component charts if the data is overtime or more complex you have only one case (use a pie chart).
Points to watch put the bars into an order that gives the clearest numerical progression you can achieve (unless the data is in categories with a fixed order or is chronological avoid sequences which give a jumbled appearance unless a pattern is visible don’t use this type of chart show the percentage shares as a number inside the bar components (at least for large components use clearly distinct shadings and labels for components.
