 ## Parameters
 
 - `points` : The list of `[x, y]` points of the polyline. The points are indexed from 0 to n-1.
-- `width` : The line width.
+- `width` : The line width. Default to 1.
 - `startingStyle` : The end-cap style of the starting point. The value must be `"CAP_BUTT"`, `"CAP_SQUARE"` or `"CAP_ROUND"`. The default value is `"CAP_SQUARE"`. 
 - `endingStyle` : The end-cap style of the ending point. The value must be `"CAP_BUTT"`, `"CAP_SQUARE"` or `"CAP_ROUND"`. The default value is `"CAP_SQUARE"`. 
 - `joinStyle`: Applies to the vertex where two lines join. The value must be `"JOIN_ROUND"`, `"JOIN_MITER"` or `"JOIN_BEVEL"`. The default value is `"JOIN_ROUND"`. Since 2.4.
