I' trying to customize label in RTPieBuilder this is my sample.
b := RTPieBuilder new. b interaction popup. b view: v. b objects: listByRegion associations. b slice: [ :e | e value size ]. b globalRule distinctColor. "b labelled." b label: (RTLabel new text: 'label test'). b build.
I commented "b labelled", but when I try to set label with RTLabel I get it error in trachelShape, there is a way to set a custom label?
