Range and interval
Compare minimum, maximum, and mean values by category.
Chart ID: rangeInterval. Independent import: @revolist/charts/range-interval.

Reading the chart
Section titled “Reading the chart”Compare explicit intervals and their representative values. Supply semantic bound channels; arbitrary series positions are not a reliable substitute for those identities.
Data requirements
Section titled “Data requirements”Bind the lower and upper (or start/end) channels explicitly. Bounds must be finite numeric observations or explicit nulls. A missing bound omits that interval rather than inventing an endpoint.
The roles below describe the chart's data contract. Generic category/value roles resolve from the dataset; explicitly bind specialized numeric roles as shown in the complete example.
| Data role | Field count |
|---|---|
category | 1 or more |
value | 1 or more |
series | 2–3 |

Create this chart
Section titled “Create this chart”Install the package using the installation guide, give the host an explicit height, and call createRangeIntervalChart after the host mounts. This factory fixes the chart type to rangeInterval.

Supported options
Section titled “Supported options”Set these fields in chartOptions. The option schema validates supported keys, ranges and choices; updating chartOptions replaces that authored object.
| Option | Default | Accepted values |
|---|---|---|
showGridLines | true | true or false |
markOpacity | 1 | 0.2 to 1; step 0.05 |
Titles, legends, theme and labels belong to presentation or the corresponding top-level setting. Axis, color, navigation and interaction support depends on the selected chart; see Data & Configuration.
Related charts
Section titled “Related charts”- Error interval — Compare a center value with its lower and upper bounds.
- Box plot — Summarize a distribution with quartiles, whiskers, and outliers.
- Violin plot — Compare distribution shape and concentration across categories.
