Hi, Ista, 1. /"df.m <- transform(df.m, Period = reorder(Period, -1*value))
ggplot(df.m, aes(x = Period, y = value/1e+06, fill = Region)) + geom_bar(stat = "identity", position = "stack") "/ I have followed your instruction but I found the sequence did not change. 2. I am looking for the stack value, I have read many threads and eventually I think I should make a new frame and reorder it, after order it and put it as a new level for df.m and let it identify the sequence... I am still exploring how to intergrate it to the melt data df.m Thanks... -- View this message in context: http://r.789695.n4.nabble.com/ggplot-rank-stack-bar-automatically-tp4391042p4399172.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
