Re: [R] overlaying two graphs / plots /lines
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.

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 y axis : 9, 0, 89, 1000, 90, 1001. ... (200 elements).
Thanks a lot,

Hello,
Here is a ggplot way.
I'll use the same data.
On each data.frame, create an id column, saying which df it is.
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
suppressPackageStartupMessages({
library(dplyr)
library(ggplot2)
})
bind_rows(
A %>% mutate(id = "A"),
B %>% mutate(id = "B")
)
#> xy id
#> 1 1 39 A
#> 2 7 91 A
#> 3 9 100 A
#> 4 203 A
#> 5 109 B
#> 6 21 89 B
#> 7 67 1000 B
#> 8 99 90 B
#> 9 200 1001 B
To do this in a pipe doesn't change the original data.
Then pipe the result to ggplot separating the lines by mapping id to
color. ggplot will automatically take care of the axis ranges.
bind_rows(
A %>% mutate(id = "A"),
B %>% mutate(id = "B")
) %>%
ggplot(aes(x, y, colour = id)) +
geom_line() +
theme_bw()
Hope this helps,
Rui Barradas

Re: [R] overlaying two graphs / plots /lines
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.

[R] overlaying two graphs / plots /lines
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).
