The default width allowed for each monthly column in the cashflow allows cashflows in the millions of dollars, totalling to the tens of millions of dollars to be displayed and printed clearly. For cashflows larger than this, there are two options available.
On screen, the width of columns can be adjusted by pointing the mouse to a dividing line between the month labels at the top of the screen, and clicking and dragging the divider to the right. This will increase the on screen column width of all columns.
On paper, you can ask for the report to be printed in landscape. This will allow for cashflows well over the thousands of millions of dollars.
