"...override the set data protected function - but what do I change?..."
that depends on what your renderer does.

 

I suggest that you start with a renderer that someone else has written
and modify it to meet your purposes.  Either that or start reading up on
renderers.  Some of the key parts you should learn about are:

set data() 

commitProperties()

createChildren()

updateDisplayList

measure()

I'm having the same problem, and checked out this pdf. Amy says to
override the set data 
protected function - but what do I change?

Thanks!

Right.  Or my response would be, "is your itemRenderer coded correctly?"
