Description

svg:polyline is a DrawingML or SVG namespace element used to describe a specific part of a shape, text run, theme, or graphic. In the ECMA-376 DrawingML model, it participates in the XML content tree that defines visual appearance, geometry, and formatting for OOXML content.

The element is commonly encountered in presentation, document, and spreadsheet packages where shapes, charts, pictures, or text boxes are serialized as Open XML. The examples below illustrate a typical usage pattern and a corresponding Open XML SDK implementation.

Attributes

Attribute	Type	Possible Values	Description
`points`	string	coordinate list	Polyline points.
`fill`	paint	CSS color	Fill paint.
`stroke`	paint	CSS color	Stroke paint.

XML Example

<svg:polyline points="10,10 30,30 50,20 70,40" fill="none" stroke="#009688" stroke-width="2"/>

using System.Xml.Linq;

XNamespace svg = "http://www.w3.org/2000/svg";
var polyline = new XElement(svg + "polyline",
    new XAttribute("points", "10,10 30,30 50,20 70,40"),
    new XAttribute("fill", "none"),
    new XAttribute("stroke", "#009688"),
    new XAttribute("stroke-width", "2"));

Console.WriteLine(polyline);

Notes

The permitted child elements and attribute values depend on the surrounding OOXML part and the schema version in use.
In practice, DrawingML content is usually generated from higher-level shape or picture APIs rather than built manually element-by-element.
When this element appears inside a document package, it is typically linked by relationships or contained in a drawing part that is referenced from a shape or graphic object.
