is it possible to control the behavior of the z axis in histogram2d? e.g. making it logarithmic.
Yes in Gadfly:
using RDatasets, Gadfly
D = dataset("ggplot2","diamonds")
p = plot(D, x=:Price, y=:Carat,
Geom.histogram2d(xbincount=15, ybincount=15),
Scale.color_log10,
Scale.x_continuous(format=:plain),
Guide.title("Diamonds")
)
nice! thx.
