# What kinds of data are properly displayed in a bar chart or pie chart?

Let's say you want to track how you spend your money. And this month you spent $1,000. If you want to illustrate how you spent the$1,000 by category (e.g., food, clothing, gasoline), then a pie chart may make the most sense. However, if you want to display the trend for monthly spend over time (e.g., the past 6 months), then a bar chart may be more optimal.
