A polyline is a linear overlay of connected line segments on the map.

This class extends MVCObject.

Constructor
Polyline	Polyline([opts]) Parameters:  opts:  PolylineOptions optional Create a polyline using the passed PolylineOptions, which specify both the path of the polyline and the stroke style to use when drawing the polyline. You may pass either an array of LatLngs or an MVCArray of LatLngs when constructing a polyline, though simple arrays are converted to MVCArrays within the polyline upon instantiation.

PolylineOptions interface

google.maps.PolylineOptions interface

PolylineOptions object used to define the properties that can be set on a Polyline.

Properties
clickable optional	Type:  boolean optional Indicates whether this Polyline handles mouse events. Defaults to true.
draggable optional	Type:  boolean optional If set to true, the user can drag this shape over the map. The geodesic property defines the mode of dragging. Defaults to false.
editable optional	Type:  boolean optional If set to true, the user can edit this shape by dragging the control points shown at the vertices and on each segment. Defaults to false.
geodesic optional	Type:  boolean optional When true, edges of the polygon are interpreted as geodesic and will follow the curvature of the Earth. When false, edges of the polygon are rendered as straight lines in screen space. Note that the shape of a geodesic polygon may appear to change when dragged, as the dimensions are maintained relative to the surface of the earth. Defaults to false.
icons optional	Type:  Array<IconSequence> optional The icons to be rendered along the polyline.
map optional	Type:  Map optional Map on which to display Polyline.
path optional	Type:  MVCArray<LatLng>|Array<LatLng|LatLngLiteral> optional The ordered sequence of coordinates of the Polyline. This path may be specified using either a simple array of LatLngs, or an MVCArray of LatLngs. Note that if you pass a simple array, it will be converted to an MVCArray Inserting or removing LatLngs in the MVCArray will automatically update the polyline on the map.
strokeColor optional	Type:  string optional The stroke color. All CSS3 colors are supported except for extended named colors.
strokeOpacity optional	Type:  number optional The stroke opacity between 0.0 and 1.0.
strokeWeight optional	Type:  number optional The stroke width in pixels.
visible optional	Type:  boolean optional Whether this polyline is visible on the map. Defaults to true.
zIndex optional	Type:  number optional The zIndex compared to other polys.

IconSequence interface

google.maps.IconSequence interface

Describes how icons are to be rendered on a line.

If your polyline is geodesic, then the distances specified for both offset and repeat are calculated in meters by default. Setting either offset or repeat to a pixel value will cause the distances to be calculated in pixels on the screen.

Properties
fixedRotation optional	Type:  boolean optional If true, each icon in the sequence has the same fixed rotation regardless of the angle of the edge on which it lies. Defaults to false, in which case each icon in the sequence is rotated to align with its edge.
icon optional	Type:  Symbol optional The icon to render on the line.
offset optional	Type:  string optional The distance from the start of the line at which an icon is to be rendered. This distance may be expressed as a percentage of line's length (e.g. '50%') or in pixels (e.g. '50px'). Defaults to '100%'.
repeat optional	Type:  string optional The distance between consecutive icons on the line. This distance may be expressed as a percentage of the line's length (e.g. '50%') or in pixels (e.g. '50px'). To disable repeating of the icon, specify '0'. Defaults to '0'.

Polygon class

google.maps.Polygon class

A polygon (like a polyline) defines a series of connected coordinates in an ordered sequence. Additionally, polygons form a closed loop and define a filled region. See the samples in the developer's guide, starting with a simple polygon, a polygon with a hole, and more. Note that you can also use the Data layer to create a polygon. The Data layer offers a simpler way of creating holes because it handles the order of the inner and outer paths for you.

This class extends MVCObject.
