Thanks for the reply. There is an ItemRenderer for PieSeries,
but I do not understand how that would be extended/replaced to
format the string returned from my custom labelFunction to changed
font characteristics. I looked at htmlElement, but it does not
appear to be a solution for this case.
To be clear and referring to the link from my initial post,
instead of displaying this default output from the label function:
Total Gold: 35
USA: Total Gold: 35
Where the "USA:" string is bold. It seems very simple, but I
am unclear on how to proceed. Any ideas?
