Signed CSS bars and their matching data table

Original local draft fixture. Synthetic data. No external requests or dependencies.

Focus: none recorded.

Fixture list and exact steps

  1. T12-A — mixed values. Activate “Mixed values”. Inspect the visible labels and table: Cedar 24, Juniper 0, Maple −12, Willow Missing, Birch 8. Activate “Check equivalence”. Record each pair and allEqual.
  2. T12-B — geometry. In Mixed values record the diagnostics for bar left/width percentages. Zero is a marker, Missing is text, positive bars extend right from the midpoint and negative bars extend left. Inspect, rather than infer from the numbers, whether the visible chart agrees.
  3. T12-C — zero dataset. Activate “All zeros”, then “Check equivalence”. There should be five zero markers and no missing value. The scale remains −30 to 30. Record the actual labels and equality result.
  4. T12-D — resize and keyboard. Activate “Mixed values”, then “Narrow to 320 px”. Tab through all buttons and record focus. Inspect chart labels and table at that width; record any clipping. The table has its own overflow wrapper.
