Presenting indicators using symbols

In addition to presenting indicators in graphical form, you can also use symbols (Figure 20) to depict
the status of indicators. Symbols communicate complex information in ways that are easily and quickly
understood. Changes in the value of the indicator may be shown using up and down arrows, and an
indication of whether the change is favourable or unfavourable may be shown using, for example, a

happy/frown face or green and blue colours.
