The Trends tool shows your spending by category in a timeline view. It can show as little as 3 months or as much as 12 months. It can help you visualize your spending patterns by category over time and plan for unexpected or seasonal increases in spending. (Examples include higher travel costs for summer vacations or increased holiday shopping.) When you find spending you want to learn more about, you can select the graph and see details by spending category, as well as specific transactions.
