Stroke Width

[yuliyang]

strokeWidth didn't work, it should be stroke-width.

this.set_attr(path, {
        fill: data[i].color,
        stroke: settings.stroke_color,
        'strokeWidth': settings.stroke_width,
        'data-cx' : cx,
        'data-cy' : cy,
        'data-id' : 's' + i
      });
