Tools that are numeric and pictorial are usually limited by the complexity of the data that they can display. For example, a complex graph containing a dozen different lines can be extremely difficult to interpret. This type of data may be better shown in a numeric, non-graphical format. These have the advantage of showing exact numbers, but lose the impact and ability to highlight decision points of more graphical displays.

Description

Some tools involve calculation, but of too few numbers to be displayed in a matrix. Where these result in a single number, then there is usually no alternative way of displaying it, other than writing it large, although if this calculation changes across time, then it may be shown in a line graph.

Where there are a simple set of calculations, then they may be displayed in a table.
