What color scale should be used on a geom_bin2d?

[Mauricio]

geom_bin2d default behavior uses light and dark colors for high and low density, respectively.  I would prefer to reverse the scale so denser areas are darker.  What color scale should be used?  And how?

Thanks

Use scale_fill_continuous, with whatever colors you want.

args(scale_fill_continuous)

will show you the defaults, so reversed would be

d <- ggplot(diamonds, aes(x, y)) + xlim(4, 10) + ylim(4, 10)
d + geom_bin2d() + scale_fill_continuous(low = "#56B1F7", high = "#132B43")


Or you could do

d + geom_bin2d() + scale_fill_continuous(low = "green", high = "black")

or whatever colors you prefer. See

Best,
