How to change the size of dots in dotplot created by using ggplot2 in R?

R ProgrammingServer Side ProgrammingProgramming

To change the size of dots in dotplot created by using ggplot2, we can use binwidth argument inside geom_dotplot. For example, if we have a data frame called df that contains a column x for which we want to create the dotplot then the plot with different size of dots can be created by using the command ggplot(df,aes(x))+geom_dotplot(binwidth=2).

Example

Consider the below data frame −

 Live Demo

x<-rpois(20,5)
df<-data.frame(x)
df

Output

   x
1  1
2  3
3  6
4  3
5  5
6  11
7  2
8  3
9  2
10 6
11 5
12 4
13 4
14 6
15 8
16 6
17 8
18 9
19 4
20 7

Loading ggplot2 package and creating a dotpot for data in df with different size of dots −

Example

library(ggplot2)
ggplot(df,aes(x))+geom_dotplot(binwidth=1)

Output

Example

ggplot(df,aes(x))+geom_dotplot(binwidth=0.5)

Output

Example

ggplot(df,aes(x))+geom_dotplot(binwidth=2)

Output
