ggplot2: Bring one line to the front, but save the colors

Question

Consider the following code:

library(ggplot2)
foo <- data.frame(x=1:10,A=1:10,B=10:1)
ggplot(melt(foo,id.vars=\"x\"),aes(x,value,color=variable))+geom_lin         


        

Answer 1

The order of your A,B inside data.frame(x=1:10,A=1:10,B=10:1) is causing this layering issue because it is drawing A (1:10) first.

If you use data.frame(x=1:10,A=10:1,B=1:10) is will put the ascending line on top (since B is drawn last).
