It works! Thanks a lot for your explanations, Michael. Good luck, Mario Von: R.

Re: [R] ColorBrewer question
I believe you need to use the scale_fill_brewer since fill is the color of the bars while color is the outside of the bars in ggplot2-speak: E.g., with built-in data (it's polite to provide yours so that your minimal working example is working): data(diamonds) ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color = clarity)) # Note the borders are now changed but the fill is the same ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color = clarity)) + scale_color_brewer(pal = Blues) # Now the fill is changed, but you probably want to drop the border coloring since it's hideous against the blues ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity, color = clarity)) + scale_fill_brewer(pal = Blues) # So lovely ggplot(diamonds, aes(clarity)) + geom_bar(aes(fill = clarity)) + scale_fill_brewer(pal = Blues) Michael On Sun, Jan 29, 2012 at 12:21 PM, Mario Giesel rr.gie...@yahoo.de wrote: Hello, R friends, I'm trying to change colors of my horizontal bars so that they show a sequence.
