Enhancing scatterplots with smoothed densities

P. H. C. Eilers, J. J. Goeman

Motivation: Scatterplots of microarray data generally contain a very large number of dots, making it difficult to get a good impression of their distribution in dense areas. Results: We present a fast and simple algorithm for two-dimensional histogram smoothing, to visually enhance scatterplots.
