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 th

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

[R] overlaying two graphs / plots /lines

2023-02-07 Thread Bogdan Tanasa
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 datafra
