Hello,
I am an experience PHP developer. Check out a very similar project that I have and am still working on at www.yieldbuddy.com. Go to the 'Screenshot' section and you'll see that what you are asking is very similar to my project. Yieldbuddy used highcharts in the past but I switched to Google charts due to the licensing involved. I have saved all my old project files from when I was still using highcharts and can reference that material, thus speeding up the job. The backend was all MySQL, so no problem there either.
I hope to hear from you soon. I'm easy to get a hold of: Skype, IRC, e-mail, Google hangouts, etc.
Cheers,
Warren
