ggplot2 geom_bar arrangement
You just have to change the levels of the factor ... library(ggplot2) Lab = c(letters[4:6], letters[1:3]) valuex = c(3.1,2.3,0.4,-0.4,-1.2,-4.4) df <- data.frame(Lab,valuex) # set the factor levels to the same order as observed in the data frame df$Lab <- factor(df$Lab, levels=unique(df$Lab)) px <- ggplot(df,aes(Lab,valuex,label=Lab)) + geom_text(aes(y=0)) + geom_bar(stat = "identity") px Jean

Hi,
I was trying to draw a geom_bar plot. However, by default, the bars are
arranged according to the label, which I don't want. I want the bars to
appear exactly as they appear in the data frame. For example in the code:
Lab=c(letters[4:6],letters[1:3])
valuex = c(3.1,2.3,0.4,-0.4,-1.2,-4.4)
df <- data.frame(Lab,valuex)
px <- ggplot(df,aes(Lab,valuex,label=Lab)) + geom_text(aes(y=0)) +
geom_bar(stat = "identity")
px
The default arranges the bars in order 'a' through 'f', but I want them
arranged as per df.
How can I do this?
thanks!
