After a chart has been reduced (see rule no.2), highlighting can now be used consciously. It guides the reader and shows which information is particularly important. A color or shape that differs from the rest automatically attracts the reader’s attention. A standardized highlighting color should be used for all dashboarding. There are many possible applications – for example, the current value can be marked during developments and columns or only individual values can be highlighted in tables. Highlights are also useful for commenting. If there is a high information density, even an entire diagram can be colored or framed.
