How to create histogram with varying binwidth using ggplot2 in R?
To create histogram with varying binwidth using ggplot2 in R, we can follow the below steps −
First of all, create a data frame.
Then, use geom_histogram function with breaks argument having varying differences.
Example
Create the data frame
Let’s create a data frame as shown below −
x<-rnorm(25) df<-data.frame(x) df
Output
On executing, the above script generates the below output(this output will vary on your system due to randomization) −
x 1 -0.51481721 2 -0.15054169 3 -0.47070913 4 0.15570184 5 0.30182716 6 0.27027150 7 -1.13936013 8 1.78922492 9 -1.80448026 10 -0.50952246 11 2.06501828 12 0.18205980 13 -1.09307457 14 -0.69088644 15 -0.01556974 16 -0.18344297 17 0.56017703 18 0.90763553 19 1.63306307 20 0.83391193 21 0.09490660 22 -1.42484122 23 -0.52230854 24 0.77694351 25 -2.17216831
Create histogram with varying binwidth using ggplot2
Using geom_histogram function with breaks argument having varying differences to createthe histogram having different binwidths as shown below −
x<-rnorm(25) df<-data.frame(x) library(ggplot2) ggplot(df,aes(x))+geom_histogram(breaks=c(-3,-2,-1,2))
