Alternative to scatterplot plotting in matlab

Question

I am plotting a map between x,y and density. x and y are distances. Is there any other method apart from scatterplot to plot it. I want the density to be shown in colorbar. I have been doing the following:

scatter(x(1:end-1), y(1:end-1), 5, g);
colorbar('eastoutside');
caxis([12 max(g)]);

Answer 1

Use surf(x,y,z), in which x, and y are your distances and z is density.
