The problem with that is that in Plot A the data are more scattered across a 2 x 2 grid whereas in Plot B the data are more concentrated in fewer cells. Hence, Plot A has a few very dense grid cells and plot B has nothing as dense as plot A.

AT PRESENT, each plot uses the full range of densities; hence, this makes it seem as if each plot has the maximum highest and minimum lowest densities.

With the 'lattice' or 'centroids' styles you can use the maxarea=
argument to plot.hexbin or to grid.hexagons.
survey::svycoplot() is an example of this: you can either have the
same scale across panels or have each panel use the full range of
