How to increase the width of axes using ggplot2 in R?
To increase the width of axes (both X-axis and Y-axis at the same time) using ggplot2 in R, we can use theme function with axis.line argument where we can set element_line argument to a larger value.
Check out the Example given below to understand how it can be done.
Example
Following snippet creates a sample data frame −
x<-sample(0:9,20,replace=TRUE) y<-sample(0:9,20,replace=TRUE) df<-data.frame(x,y) df
The following dataframe is created
x y 1 6 9 2 7 8 3 1 3 4 2 4 5 1 2 6 2 5 7 2 4 8 1 6 9 4 1 10 7 6 11 0 8 12 9 0 13 9 4 14 1 8 15 6 5 16 7 7 17 0 0 18 6 7 19 1 6 20 6 8
To load ggplot2 package and create scatterplot between x and y on the above created data frame, add the following code to the above snippet −
x<-sample(0:9,20,replace=TRUE) y<-sample(0:9,20,replace=TRUE) df<-data.frame(x,y) library(ggplot2) ggplot(df,aes(x,y))+geom_point()
Output
If you execute all the above given snippets as a single program, it generates the following Output −
