The 
Account Chart for Cumulative Returns displays the cumulative total of the returns an Account earns each month. The total shown for each month includes the interest earned that month plus the sum total of all the returns earned in previous months. For any Account that does not earn a return (such as the default cash Account) the line representing it will always be flat at zero.
