In a nut shell: A plotting algorithm should sample the function the same way a numeric integration routine does. The number of samples in a given interval should depend on how the function oscillates. For one dimensional plotting and for references to a description of the algorithm see: https://github.com/soegaard/bracket/blob/master/plotting/adaptive-plotting.rkt I have collected "horror" examples to test the plotting routine. See the end of the file. /Jens Axel ____________________ Racket Users list: http://lists.racket-lang.org/users
