How do you show comparison on a graph?
If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart. If you want to show trends and patterns in your data, use a line chart, bar chart, or scatter plot.

Researchers have found that bar charts are much easier for people to comprehend than other types of charts (like pie charts). This is because bar charts make it easy for people to quickly and accurately perceive the differences between values.
