You are talking about something else.And if you are talking about this something else, then what you are doing is completely useless and irrelevant, since a pie chart with n "slices" provides you with a map that requires at least n colors, for any positive integer n and all your ruminations are useless and irrelevant.Clear now, or will you again ignore it and repeat the same ignorant nosense in the hope that repetition will stand in for information?-- Arturo Magidin
