gradient breaks in a ggplot stat_bin2d plot

Question

I have a 2d histogram created with stat_bin2d in the ggplot2 package. I\'d like to control both the number of breaks in the color gradient, as well

Answer 1

Me thinks you probably want the less talked about cousin of scale_colour_gradient2(), scale_fill_gradient2()

Using your data:

p + scale_fill_gradient2(breaks=c(1,2,3,4,5,6))

Also note the optional parameters low, mid, and high for additional controls.
