Dear all, Any suggestions on how I could overlay two or more graphs / plots / lines that have different sizes and the x axes have different breakpoints. One dataframe is : A : on x axis : 1 , 7, 9, 20, etc ... (100 elements) on y axis : 39, 91, 100, 3, etc ... (100 elements) The other dataframe is : B : on x axis : 10, 21, 67, 99, 200 etc .. (200 elements). on y axis : 9, 0, 89, 1000, 90, 1001. ... (200 elements). Thanks a lot, Bogdan [[alternative HTML version deleted]]
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.

It's easy enough to do this, the question is "what does it MEAN?" If you overlay two graphs, what comparisons will people naturally make, and what do you want them to make? What transformations on the x axis would make two vertically aligned points about the "same" thing? What transformations on the y axis would make a vertical displacement of 1cm equally important for the two frames? This *semantic* alignment of the tables is too important to leave up to some blind algorithm.
