Hi Ioanna, You actually have three lines, and on that basis I suggest (with corrected example): X1<-c(0,1,2,3,4) Y1<-c(0,1,2,3,4) Y2<-c(5,6,7,8,9) Y3<-c(32,33,34,35,36) plot(X1,Y3,pch=20,ylim=c(0,36)) lines(X1,Y1,lty=1,type='o') lines(X1,Y2,lty=1,type='b') lines(X1,Y3,lty=2) legend(1.5,25,paste("Number",1:3),lty=c(1,1,3),pch=c(1,1,20)) Jim ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
