A 1-dimensional map with chaotic solutions for some parameter values. This shows the first circa 100,000 iterations, with value (x) on the vertical access) and "time" (strictly, iteration number, N) on the horizontal access, for a chaotic example. Each point is given a circular marker. The colour of each marker is determined by a set of RGB triples. The R channels goes from 0 to 1 on the vertical axis. The G channel goes from 0 to 1 on the horizontal axis. The B channel cycles from 0 to 1 in 23 steps, repeatedly, hence not mapping to either axis.

Does anyone else get the (illusory) impression that the background grey is not a constant shade? It's actually RGB = 0.5 0.5 0.5 uniformly across the whole area!
