How do I draw a Polygon?

[earthling4211573]

I've been trying draw Polygons but am getting the error: "array[i] is undefined fabric.js/all.js Line 1647".

Example of tries:
canvas.add(new fabric.Polygon({
points: [obj1, obj2, obj3, obj4] //obj has .x and .y
}));

canvas.add(new fabric.Polygon({ 
    points: [[thisPathRect[0][0],thisPathRect[0][1]], [thisPathRect[1][0],thisPathRect[1][1]], [thisPathRect[2][0],thisPathRect[2][1]], [thisPathRect[3][0],thisPathRect[3][1]]]
}));

Any ideas? (There don't seam to be any example on how to create a Polygon in fabric.js, I guess my best bet apart from asking here is understanding http://kangax.github.com/fabric.js/docs/symbols/src/src_polygon.class.js.html ).

Just noticed that when initializing the points are not an "option" but come before the options: "..initialize(points, options)..", so something like this will work:

    poly = new fabric.Polygon([{ x: thisPathRect[0][0]+translate[0], y: thisPathRect[0][1]+translate[1] },
                                     { x: thisPathRect[1][0]+translate[0], y: thisPathRect[1][1]+translate[1] }, 
                                     { x: thisPathRect[2][0]+translate[0], y: thisPathRect[2][1]+translate[1] }, 
                                     { x: thisPathRect[3][0]+translate[0], y: thisPathRect[3][1]+translate[1] }], { 
        stroke: "#000000", 
        strokeWidth: 5,
        fill: tolColors[0], 
        opacity: 1.0
    });
    canvas.add(poly);
