Why is my child so scared of strangers? Matplot has a built-in function to create scatterplots called scatter(). The map_offdiag() seems to pass a default color argument and that is the reason this argument is overriden inside the density_scatter_plot() function. The plot function will be faster for scatterplots where markers don't vary in size or color. Plotting millions of points can be slow. It is really useful to study the relationship between both variables. The scatter_density method takes the same options as imshow (for example cmap, alpha, norm, etc. How can I plot scatter plots over a shapefile using Python?
