Can't really use roadmap graphics like that - they rarely can be broken down to correlate exactly with dates.
Best you can do is start / middle / end of a year. And even then you probably looking to get more details than are available.
Please remember that any mention of competitors, hinting at competitors or offering to provide details of competitors will result in an account suspension. The full rules can be found under the 'Terms and Rules' link in the bottom right corner of your screen. Just don't mention competitors in any way, shape or form and you'll be OK.
