Replacing your PHP with static numbers seems to work fine. I suspect your
PHP is wrong somewhere outside the scope of the charting API.
Have you tried just inserting static data to see if and chart renders? Have
you put a breakpoint, and looked to see that the PHP is generating proper
JS? What's the console output say? Any errors from you PHP?
