A histogram is used to summarize discrete or continuous data. If your scattered data is rather dense, a simple 2D histogram may be all you need. Use Matlab to generate plots of the 2D Gaussian density function given by: where the correlation coefficient rho is in the range (-1 < rho < 1). Generate x and y vectors from -2 to +2 with spacing of 0.05. Using subplots, generate surface plots for the following values of the correlation coefficient: rho = -0.95, -0.5, 0, 0.5, 0.95 Data density can be hard to read from scatter plots due to overstriking. I therefore calculate data density at each pixel as the reciprocal of the sum of squared distance from each point, adding a fudge factor to prevent points actually within the pixel going to infinity. The resulting plot allow for a visual fix on data density.Fill the contour with stat_density_2d Note that there is a similar function named stat_density_2d that allows changing the geom used.
