Check whether the outcome improved
Define axis assertions
Write expected unit, domain, scale type, zero treatment, tick values, label precision, and mark ordering for every fixture. State whether outliers extend the domain or receive a separate treatment. A pass requires the chart to reveal enough context for the intended comparison.
Exercise range boundaries
Run ordinary, outlier, negative, zero, narrow-range, and large-range fixtures through the chart and its companion table. Compare numeric values, rendered positions, ticks, tooltip text, and export values. Include a filter that changes domain so automatic rescaling is observable.
Review the visual claim
Ask a reviewer to state the comparison supported by the axis and the units attached to it. Preserve raw fixture, filter state, chart revision, and evidence. Record a bounded outcome when the chart is analytically correct but its scale or purpose requires nearby explanatory text.
What to carry forward
Verification passes when values, domains, scales, ticks, units, and visual explanation agree across reviewed cases. Report a bounded pass for uncovered scale modes. Keep verification inconclusive when clipping, zero treatment, or unit labels could lead a reader to a different conclusion.
