Humans are visual creatures!
The key difference between Basic and Advanced Analysis Mode is the amount of control you have over input parameters and the results you see for Monte Carlo or Historical Analysis. When Basic Mode is selected the default settings are run whenever the "Refresh Your Trajectory" button is clicked. This button is displayed whenever you are in Basic Mode with either analysis type selected and a data change is made, as shown below:
When Advanced Mode is selected the "Advanced Analysis & Results" window is displayed, as shown below:
For more information on how to configure Monte Carlo and Historical Analysis or how to interpret the rich data that OnTrajectory produces, see the guide Monte Carlo & Historical Analysis.
The orange line, which is shown by default (as below) depicts either your Assets or your Net-Worth and is based on the growth rates of your investments (defined in the "% Growth" column on the Accounts table).
If you uncheck the option "Show Average % Growth Trajectory", both the orange line and the % Growth column will be hidden.
Viewing your Trajectory 'As Assets' is the default view, meaning that as you accrue funds (even if you have debt), the line will go up. If you have defined 'debt' associated with an expense — and you wish that amount to be deducted from view, choose the 'As Net-Worth' option.
Finally, the Focus on Deficit-Period option allows you to automatically "zoom-in" on periods of time when your assets/net-worth have gone negative and you wish to visually focus on that range of time — until of course you get out of debt!
By default, everything you do in OnTrajectory is in "Today's Dollars" — the advantage of this approach is that you can always think about future expenses (and income) in terms of what things cost now and not have to worry about inflation. However, if you'd like to see amounts expressed in "Tomorrow's Dollars" (not compenstated for inflation), select the "Show in Tomorrow's Dollars" option. Note that this applies only to values in the graph, values listed in the Income/Expense/Accounts item tables are always expressed in Today's Dollars.
The other option in this section is Employ a Debt Reduction Strategy. This option is only available if you have defined "debt" either from the item properties (wrench icon) of an expense or as a loan associated with a Home Equity account. If you have debt you can experiment with different pay-down strategies — specifically "Snowball" or "Avalanche".Snowball is an approach where you pay down your smallest debts first, Avalanche pays down debt with the highest interesest rate first. For more information, please see the guide Dealing with Debt.
Finally, there are several other ways to view your information based on your own personal situation.
