aes_string. Only needs to be set at the layer level if you are overriding the plot defaults.
layer. This can include aesthetics whose values you want to set, not map. See

Add heatmap of 2d bin counts.

d <- ggplot(diamonds, aes(x = x, y = y)) + xlim(4,10) + ylim(4,10) d + geom_bin2d()
d + geom_bin2d(binwidth = c(0.1, 0.1))
