| Field | Type | Required |
|---|---|---|
| title | string (optional, e.g., 'API Response SLA') | optional |
| value | number representing current value (e.g., 99.4) | required |
| max_value | number representing maximum gauge scale (e.g., 100) | required |
| unit | string (optional, e.g., '%') | optional |
| label | string (optional, e.g., 'SLA Met') | optional |
| min | number (optional, default 0). Setting min or steps switches to the scale mode (Plotly indicator gauge) with bands, a threshold tick, a needle, a legend and a hidden table. | optional |
| steps | list of {from, to, color} bands on the scale (up to 8); color is a hex or var(--token), default theme colours; each band is also listed in text. | optional |
