R-listers, My colleagues and I are working on wind roses using station information and we have a question regarding the plotting of rings of the wind rose (see attached for example). What we would like to do is to add an extra frequency ring to the wind rose, so it goes up to 15% for instance and that none of the pedals going beyond the outside frequency ring. Anyone have ideas on how to do this? The package used is the circular package.
