Is there a built-in way to do a logarithmic color scale in ggplot2?

by

Yes! There is a trans argument to scale_fill_gradient, which I had missed before. With that we can get a solution with appropriate legend and color scale, and nice concise syntax. Using p from the question and my_breaks = c(2, 10, 50, 250, 1250, 6000):

p + scale_fill_gradient(name = "count", trans = "log",
                        breaks = my_breaks, labels = my_breaks)

My other answer is best used for more complicated functions of the data. Hadley’s comment encouraged me to find this answer in the examples at the bottom of ?scale_gradient.
