After reading your question again I came up with these plots. dataset <- data.frame(x = c(rnorm(1000), rnorm(200, mean = 1)), y = gl(2, 100, labels = LETTERS[1:2])) ggplot(dataset, aes(x = x, group = y)) + stat_bin(aes(fill = ..count..), width = 0.2) + scale_fill_gradient(low = "red", high = "green") ggplot(dataset, aes(x = x)) + stat_bin(aes(fill = ..ncount..), width = 0.2) + scale_fill_gradient(low = "red", high = "green") + facet_grid(. ~ y) ggplot(dataset, aes(x = x)) + stat_bin(aes(fill = ..count..), width = 0.2) + scale_fill_gradient(low = "red", high = "green") + facet_grid(. ~ y)

Borchers Verzonden: dinsdag 8 juli 2008 14:23 Aan: r-help@r-project.org Onderwerp: Re: [R] Histogram with colors according to factor No; thanks for your try, but this is not what I want. Here each bar has one single color. I would like to render each bar with several colors according to the distribution of a factor. I now learned that this is called "stacked histogram" (damned Excel). In the following entry https://stat.ethz.ch/pipermail/r-help/2007-April/129645.html Deepayan Sarkar has provided a solution though he doubts its value. Still, I find "stacked histograms" a vuable tool during exploratory data analysis. Hans Werner Is this what you want? dataset <- data.frame(x = c(rnorm(100), runif(100), rchisq(100, 1)), y = gl(3, 100, labels = LETTERS[1:3])) ggplot(dataset, aes(x = x, fill = y)) + geom_histogram() ggplot(dataset, aes(x = x, fill = y)) + geom_histogram(position = "dodge") HTH, Thierry ----- ---- Hans W.
