PolyLine

A series of connected line segments. Unlike most label objects, PolyLine does not use a position anchor — coordinates are specified directly in the points array.

Mandatory properties

Property	Type	Description
type	string	Must be PolyLine.
points	array	Flat array of coordinates: [x0, y0, x1, y1, ...]. Must contain at least 4 values (one segment).

Optional properties

Property	Type	Description
lineWidth	number	Line width. Default is 1.
color	string	Line color. May contain dynamic text. Default is black.
segments	array	Dash pattern as alternating [dashLength, gapLength, ...] values. If omitted, a solid line is drawn.

Example

{
    "type": "PolyLine",
    "points": [10.0, 10.0, 50.0, 10.0, 50.0, 40.0],
    "lineWidth": 1.0,
    "color": "black"
}

Dashed line example:

{
    "type": "PolyLine",
    "points": [10.0, 20.0, 90.0, 20.0],
    "lineWidth": 0.5,
    "segments": [5.0, 2.0]
}
