WebJul 12, 2024 · Two methods can be used to compute the density: either 'Precise': the density is estimated by counting for each point the number of neighbors N (inside a sphere of radius R) or 'Approximate': the density is simply estimated by determining the distance to the nearest neighbor (which is generally much faster). WebJul 3, 2024 · Basically, the parts of the scatter plot with the most densely clustered data points would be dark red, semi densely clustered data points would be medium red, and sparsely clustered data points would be light red. This is the way that I was thinking of, but (hopefully) there might be a simpler function or command to do this.
