Hi Bogdan,
Try this:
A<-data.frame(x=c(1,7,9,20),
y=c(39,91,100,3))
B<-data.frame(x=c(10,21,67,99,200),
y=c(9,89,1000,90,1001)) # one value omitted to equalize the rows
xrange<-range(c(unlist(A$x),unlist(B$x)))
yrange<-range(c(unlist(A$y),unlist(B$y)))
plot(A,type="l",xlim=xrange,ylim=yrange,col="red")
lines(B,lty=2,col="blue")
legend(150,400,c("A","B"),lty=1:2,col=c("red","blue"))
There are other tricks to deal with the differences in range between A and B.
