I can customize all of the callouts on a pie chart by setting the 'calloutStroke' property, but that falls a bit short of the design I have been handed. I was wondering if anyone had any ideas about ways to customize each of the callouts to match the color I have given that wedge slice (via the 'fills' style).
As it stands, I suspect I am going to have to invent my own label callouts that I actually draw onto the chart manually? It doesn't seems there is even a CalloutStroke class that could potentially be overloaded to do this sort of thing, so I am not sure what else I can do.
