Doesn't appear yoy bothered to read my question in its entirety - just shot off a stock answer - incredibly unhelpful.
In FusionCharts.js in v3 there is NO METHOD named feedData. NONE, NADA, NOT THERE.
Thus, things that call feedData DO NOT WORK.
Based on your response, it is no surprise that your demos call non-existent methods.
So, do you support the method feedData, and, if not, why not??????????
