Setting overlays above polylines in google maps

I have been trying to开发者_运维问答 set overlay above polylines using zindex. I have tried using

overlay.getPanes().overlayLayer.style['zIndex'] = 1001; 

and setting zindex of polylines to 1. Does anyone know the correct method to have the overlays appear above polylines?

Try putting it on a higher pane, 'floatPane' being the highest.
