bar family
bar-range
Floating bars showing a low-to-high range per category.
Each bar is positioned between its minimum and maximum value, not anchored to zero. Reads as "category X falls between A and B". Common for cost ranges, salary bands, asset price ranges.
When to use
Showing variability or range without summarising to a midpoint. Cost benchmarking ($/MWh ranges) and salary surveys are textbook cases.
When NOT to use
You have a single value per category (use bar) or paired comparisons (use dumbbell).

Disambiguation rules
- Bars do NOT share a baseline. Each starts at its category's minimum value.
- If the bar has dots at the endpoints, it is dumbbell, not bar-range.
- If bars are cumulative (each starts where previous ended), it is waterfall.
