[R] Superimposing 2 curves on the same graph with par(new=TRUE)
Dear R-Experts, I try to superimpose/present 2 curves/plots on the same graph. I would like the result/graph to be readable. For that, I use the par(new=TRUE) argument but on the Y-axis there is a superposition of writings and the Y-axis becomes unreadable. How can I solve this problem ? Here is a reproducible example : Date<-c(1970,1971,1972,1973,1974,1975,1976,1977,1978,1979,1980,1981,1982,1983,1984,1985,1986,1987,1988,1989,1990,1991,1992,1993,1994,1995,1996,1997,1998,1999,2000,2001,2002,2003,2004,2005,2006,2007,2008,2009,2010) MORTSFr<-c(16445,17671,18113,17043,14738,14355,15028,14283,13229,13603,13672,13547,13527,13021,12737,11388,11947,10742,11497,11476,11215,10483,9900,9568,9019,8891,8541,8444,8918,8487,8079,8160,7655,6058,5593,5318,4709,4620,4275,4273,3992) MORTSBu<-c(838,889,934,946,960,1030,1021,1040,1153,1149,1199,1219,1229,1123,1119,1113,1070,1153,1153,1280,1567,1114,1299,1307,1390,1264,1014,915,1003,1047,1012,1011,959,960,943,957,1043,1006,1061,901,776) plot(Date,MORTSFr,type="l") par(new=TRUE) plot(Date,MORTSBu,lwd=2,lty="dashed") Thanks for your time.

[R] Superimposing 2 curves on the same graph with par(new=TRUE)
Here is how:
plot(Date,MORTSFr,type="l", ylim=c(0,max(MORTSFr)))
points(Date,MORTSBu,type="l",lty=2)
If you don't use the same scale for the two plots, you are probably
misrepresenting the data. If you want to plot relative change, normalize the
data before plotting.
norm <- function(x) {(x - min(x))/(max(x) - min(x))}
plot(Date,norm(MORTSFr),ylab=c("Relative Change"),type="l")
points(Date,norm(MORTSBu),type="l",lty=2)

[R] Superimposing 2 curves on the same graph with par(new=TRUE)
... which is exactly what he shouldn't do because now it the plot falsely asserts that both curves are plotted to the same scale. B.
