How to change the default type of points for scatterplot using ggplot2 in R?
To change the defaults for ggplot2 geoms, we need to use update_geom_defaults function. If we want to change the shape of points for scatterplot, we can use the below syntax −
update_geom_defaults("point",list(shape=”point_shape_number”))
The point shape number ranges from 0 to 25. We can change that according to our need.
Consider the below data frame −
Example
x<-rnorm(20) y<-rnorm(20,5,0.32) df<-data.frame(x,y) df
Output
x y 1 -0.005184157 5.338089 2 -1.044878945 4.662460 3 1.154191529 5.450373 4 -0.437975797 4.649176 5 -0.220793320 5.057522 6 -0.062619288 5.003642 7 -1.023676613 4.949002 8 0.902098608 4.632925 9 -0.259247125 4.792074 10 0.305164402 5.745798 11 -0.891792853 4.458326 12 -0.451765777 4.435208 13 -0.018278677 5.525500 14 0.917192389 4.740232 15 -1.366201294 5.363222 16 -0.491698757 5.305723 17 0.680064934 5.406010 18 -1.058529703 5.084462 19 1.862063812 4.851102 20 0.433153374 4.346126
Loading ggplot2 package and creating a scatterplot between x and y −
Example
library(ggplot2) ggplot(df,aes(x,y))+geom_point()
Output
Updating point type for scatterplot of ggplot2 package and creating the plot −
Example
update_geom_defaults("point",list(shape=6)) ggplot(df,aes(x,y))+geom_point()
