Polyline Annotations
Polyline annotations are built from ordered placement points. Each point becomes a vertex, and the annotation draws straight segments through those vertices.
| Annotation | Polyline behavior |
|---|---|
| PolyLineAnnotation | The default PolyLineAnnotation📘, drawing editable line segments through the points array. |
| XABCD pattern | A five-point labelled pattern using placementPointCount: 5 when created through the placement modifier. |
| Elliott wave | A simple labelled impulse-wave example using 6 ordered polyline points. |
These examples use the same PolyLineAnnotation📘 class. Patterns such as XABCD, Elliott waves and other multi-leg shapes are configured by changing the points, labels, styling and placementPointCount; no extra annotation subclass is required.
