# forge.signals.Region

```python
forge.signals.Region(start: int, end: int, /, *, label: str | None = None, color: object = None) -> None
```

A stretch of bars to shade on the chart: ``fg.Region(start, end, label="news")``.

``start`` and ``end`` are bar numbers, both included. Regions of one plot share one colour. A
label is
written above the first bar of the region.
