Change values of X-axis to Integer
To change real axis values to integer we can use scale_x_continuous() or scale_y_continuous() functions to fix x-axis and y-axis respectively. By passing appropriate interval values to break argument the job can be done.
Syntax: scale_x_continuous(breaks =c(b1,b2,b3….bn))
Parameters:
breaks: this specifies at what intervals the value should be displayed
b1,b2,b3…bn: these values specifies each intervals
Example: Changing real values on x-axis to integer
R
library(dplyr) library(ggplot2) set.seed(10) df <- data.frame(X = rnorm(15,mean=1.199, sd=0.7622377), Y =(rnorm(15,mean=3.057, sd= 0.4358663))) df %>% ggplot(aes(x = X, y = Y)) + geom_point()+ scale_x_continuous(breaks =c(0,1,2)) |
Output:
Similarly, both values can be changed if both the functions are called together.
Syntax:
scale_y_continuous(breaks =c(b1,b2,b3,…bn))+ scale_x_continuous(breaks =c(b1,b2,b3,…bn))
Example: Changing values for both axes
R
library(dplyr) library(ggplot2) set.seed(10) df <- data.frame(X = rnorm(15,mean=1.199, sd=0.7622377), Y =(rnorm(15,mean=3.057, sd= 0.4358663))) df %>% ggplot(aes(x = X, y = Y)) + geom_point()+ scale_x_continuous(breaks =c(0,1,2))+ scale_y_continuous(breaks =c(3)) |
Output:
How to Change X and Y Axis Values from Real to Integers in ggplot2 in R
In this article, we will discuss how to change X and Y-Axes values from Real to Integers using ggplot2 in the R programming language. Let us first create a plot that contains Real values on axes and then change them to integers so that the difference will be apparent.
Example: Initial plot
R
library(dplyr) library(ggplot2) # dummy dataset set.seed(10) df <- data.frame(X = rnorm(15,mean=1.199, sd=0.7622377), Y =(rnorm(15,mean=3.057, sd= 0.4358663))) df %>% ggplot(aes(x = X, y = Y)) + geom_point() |
Output:
As you can see in the above code, the values of the X and Y axes are Real. Now let us look at various methods by which these can be changed to integer values.
