The Expense Breakdown doughnut shows what share of your spending went to each expense category. Sprwt takes every Withdrawal transaction dated from January 1 of last year to December 31 of this year, totals the amount per category and shows each category's percentage of the total. Only transactions whose category exists in your Chart of Accounts are counted. If nothing qualifies, the card shows "No expenses tracked yet – Categorize your transactions to see where your money is going" with a View transactions button.
