A MATLAB implementation of the plot described in Eilers, P.H.C. and Goeman, J.J (2004) "Enhancing scaterplots with smoothed densities", Bioinformatics 20(5):623-628.
This plot is useful when a 2D scatterplot of your data would result in an uninterpretable mass of overlaid points. The smoothed histogram displays the density of points as greyscale intensity in a 2D image plot.
Optionally, you can also plot outliers as individual points, or plot the image as a surface in 3D. |
