Display Tick Marks on Upper and Right Side of Plot Using ggplot2 in R

To display tick marks on upper as well as right side of the plot, we can create duplicate axes for X as well Y by using scale_x_continuous and scale_y_continuous functions. The argument that will help us in this case is sec.axis and we need to set it to dup_axis as scale_x_continuous(sec.axis=dup_axis()) and scale_y_continuous(sec.axis=dup_axis()). Check out the below example to understand how it can be done.

Example

Consider the below data frame −

 Live Demo

x<-rnorm(20)
y<-rnorm(20)
df<-data.frame(x,y)
df

Output

Loading ggplot2 package and creating scatterplot between x and y −

Example

library(ggplot2)
ggplot(df,aes(x,y))+geom_point()

Output

Creating scatterplot between x and y with axes on upper and right side of the plot −

Example

ggplot(df,aes(x,y))+geom_point()+scale_x_continuous(sec.axis=dup_axis())+scale_y_continuous(sec.axis=dup_axis())

Output
