I may be misinterpreting your question, but do you want something like this? x1 <- seq(0, 2, by = 0.3) x2 <- seq(3, 0, by = -0.1) # Set bar fill to white, border to green barplot(x2, col = "white", border ="green") # Set bar fill to white, border to red and add to prior plot barplot(x1, col = "white", border = "red", add = TRUE) See the 'add' and 'border' arguments in ?barplot.
