Area range · Signed intervals

Negative and positive bounds on the same scale.

Use a band when both endpoints matter. Low and high are original values; no midpoint or uncertainty is inferred.

Series require IDs and names. Each point has id, x, low and high; low ≤ high. Missing intervals require both bounds null. Category, numeric and UTC-time X are supported.

Individual or shared detail presents both endpoints. Configure colours, labels, axes, legend and viewport. No stacking, markers, point overrides or curve options.
