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 On Tue, Jun 27, 2017 at 1:43 PM, Brian Smith <[email protected]> wrote: > Hi, > > I was trying to draw a geom_bar plot.
