Create ggplot2 graph with reversed Y-axis and X-axis on top in R.

To create ggplot2 graph with reversed Y-axis and X-axis on top, we can use scale_y_reverse and scale_x_continuous function of ggplot2 package.

For Example, if we have a data frame called df that contains two columns say X and Y and we want to create the scatterplot between X and Y with reversed Y-axis and X-axis on top then we can use the below command −

ggplot(df,aes(X,Y))+geom_point()+scale_y_reverse()+scale_x_continuous(position="top")

Example

Following snippet creates a sample data frame −

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

The following dataframe is created

           x           y
1  0.59312447  0.4993337
2  0.08696615 -0.1242276

19 -1.17331809 -1.0425776
20 -1.12299141 -0.7738698

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<-rnorm(20)
y<-rnorm(20)
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 −
