Design Principle
Visual ink in charts and metrics should serve data, thresholds, and exceptions before decorative grids.
Principle
Visual ink in charts and metrics should serve data, thresholds, and exceptions before decorative grids.
Design action
Reduce grid and decoration; emphasize data marks, key points, thresholds, outlier labels, and current-state explanations.
Examples
Positive example: KPIs, trend charts, dashboards, and operational alerts need fast difference detection. Counterexample: Chart backgrounds, grids, and gradients are stronger than data marks.
Apply when
KPIs, trend charts, dashboards, and operational alerts need fast difference detection. Users need to judge state, scope, risk, or next action quickly.
