Create Facetted Plot with One Facet Displaying All Data using ggplot2 in R

To create facetted plot with one facet displaying all data using ggplot2 in R, we can follow the below steps −

• First of all, create a data frame.
• Then, create facetted plot using facet_grid function.
• After that, create the facetted plot with margins argument set to TRUE to display the plot with all data.

Create the data frame

Let's create a data frame as shown below −

 Live Demo

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
df

On executing, the above script generates the below output(this output will vary on your system due to randomization) −

x y Grp
1 2.32 0.47 C
2 0.96 0.01 C
3 0.34 0.49 A
4 1.11 0.75 C
5 0.57 0.63 C
6 0.47 0.38 B
7 0.69 0.06 A
8 1.12 1.66 C
9 0.62 0.81 C
10 0.05 0.60 C
11 0.50 0.05 A
12 0.06 0.18 A
13 0.08 1.30 C
14 2.22 0.13 C
15 0.03 0.13 C
16 0.06 0.24 C
17 0.57 1.04 A
18 0.50 0.09 C
19 1.10 0.36 B
20 0.10 0.00 B
21 1.28 0.42 A
22 1.56 0.34 A
23 1.38 0.15 A
24 0.54 0.03 B
25 1.81 1.85 A

Create the facetted plot

Use facet_grid function to create the facetted scatterplot between x and y −

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
library(ggplot2)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Grp)

Output

Create the facetted plot displaying one facet with all data

Using margins argument to create the facetted plot displaying one facet with all data as shown below −

x<-round(rexp(25,1.25),2)
y<-round(rexp(25,1.89),2)
Grp<-sample(LETTERS[1:3],25,replace=TRUE)
df<-data.frame(x,y,Grp)
library(ggplot2)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Grp,margins=TRUE)

Output
