Hi everybody,
I'm trying a multiple histogram, and I'd like to add on it a secondary axis with a line (cumulative frequencies, or wathever lines), and the 0 intercept doesnt coincide in y1 and y2, which dificult interpretation and makes presentation not nice. I had seen some related answer for boxplot, but I could not understand the code. Is there any general solution?
Thanks in advance
#example ploting a line in a multhist
a <- rnorm(100)
b<- rnorm(100)
x<- list(a,b)

par(new = TRUE)
plot(-2:2, 0:4, xaxt = "n", yaxt = "n", xlab="", ylab="",type ="l")#see #difference in 0 in y1 and y2
