If your reading is in the blue shaded area, fermentation will be complete.
That is, unless you used some dry enzyme. In that case it may well drop further.
Do not take airlock bubbling, or lack of it, as any indication of progress or completion of fermentation. Your hydrometer is the only reliable guide. The bubbling once a minute or so is simply dissolved cO² coming out of solution.
I'd leave your beer for another week. The extra week will only do good things for your beer. The yeast still works slowly away to remove some undesirable elements in the beer, and you will end up with a nicer brew.
I leave my Ales for between 2 to 3 weeks before bottling. Lagers get 3 weeks fementing, and as long as I can stand it for lagering before bottling.
Do you have temperature control for your fementer? If so, you could drop the temperature down to say 1 or 2ºC over the last 3 or 4 days before bottling. You should have clearer beer if you can do that.
