U5.03
Restraint with gridlines and reference lines
Cards in this group · 5
- U5.03.1A reference line marks a benchmark from outside the data, like a target or a historical average
- U5.03.2An unlabeled reference line reads to viewers as just one more data series, not a benchmark
- U5.03.3A reference line should sit visually between the data, which is heaviest, and the gridlines, lightest
- U5.03.4Three or four reference lines at once start competing with the real data for attention
- U5.03.5Gridlines only earn their place when a reader actually needs to read an exact value off the chart
