This is about 100,000 pairs of phi/psi proteins backbone torsion angles (ϕ,ψ) extracted from the "Top 500" PDB list using BioPython (see this page). As with any scatter plot the X coordinates of the points represent values from the first raster map and the Y coordinates represent values from the second raster map. A 2d density plot is useful to study the relationship between 2 numeric variables if you have a huge number of points. par(mfrow = c(1, 1)) plot(dx, lwd = 2, col = "red", main = "Multiple curves", xlab = "") set.seed(2) y <- rnorm(500) + 1 dy <- density(y) lines(dy, col = "blue", lwd = 2) Density Dots is scatter plots to show data density, where the points are color-mapped to the data density. Another problem we see with our density plot is that fill color makes it difficult to see both the distributions.
