Rotate a ggplot2 Graph in R

To rotate a ggplot2 graph, we can save it in an object and then use the print function by defining the angle with viewport.

For example, if we have a graph saved in an object called PLOT then we can rotate it to 180 degrees by using the below mentioned command −

print(PLOT,vp=viewport(angle=180))

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   0.096637307  -0.79663988
2  -0.972807954   0.09542357

In order to load ggplot2 package and create point chart between x and y, add the following code to the above snippet −

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

Output

If you execute all the above given snippets as a single program, it generates the following output −

In order to rotate the above plot to 180 degrees, add the following code to the above snippet −

print(Plot,vp=viewport(angle=180))

Output

If you execute all the above given snippets as a single program, it generates the following output −
