Hi Stefan, For your data, I'd suggest you consider using lines instead of bars. http://peltiertech.com/WordPress/2008/08/27/stacked-vs-clustered/ has some good reasons why. - but basically stacking makes it difficult to see how each group changes over time. It's pretty easy to play around different variations with ggplot2, so I've included a few you might want to look at. (Including your original request right at the bottom) test <- data.frame(quarter, year, category) tabdf <- as.data.frame(with(test, table(category, quarter, year))) install.packages("ggplot2") qplot(year, Freq, data=tabdf, geom="line", colour = category, facets = quarter ~ . , group = interaction(category, quarter)) # OR qplot(year, Freq, data=tabdf, geom="line", colour = quarter, facets = category ~ . , group = interaction(category, quarter)) # If you _really_ want stacking: qplot(year, Freq, data=tabdf, geom="area", fill = quarter, facets = category ~ . , group = interaction(category, quarter)) # OR qplot(year, Freq, data=tabdf, geom="bar", stat="identity", fill = quarter, facets = category ~ .) # OR finally, like what you originally asked for qplot(quarter, Freq, data=tabdf, geom="bar", stat="identity", fill = category, facets = . ~ year) Regards, Hadley -- http://had.co.nz/ __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] juxtaposed and stacked bars in one barplot?
You can simply do > a <- c(2,4,3,4,5) > b <- c(4,3,4,5,2) > barplot(cbind(a,b)) or you can put a and b in matrix as help suggests.

Hi Stefan, Could you be a bit more explicit? Do you have an example dataset that you are trying to visualise?
