Slicer and Chroma Rings options

Hi all

I’d like to know what the ‘Slicer’ and ‘Chroma Rings’ options found in the ‘Graph Control -> Slicer’ panel are supposed to do.

I ask here because ‘Slicer’ invariably crashes ColorThink Pro while ‘Chroma Rings’ seems to have no effect.

Thank you very much for your help.
