How to use scale_x_log10() / scale_y_log10() In R Language

Q: How to use scale_x_log10() / scale_y_log10() In R Language

In this method, we directly pass the parameter value in aes() function of ggplot() function as log. This is the best method as this updates the data point as well as axis tick marks and axis labels all in one go.

Method 2: Using log function in aes() function of ggplot():

We can convert the axis data into the desired log scale using the scale_x_log10() / scale_y_log10() function. we use the desired axis function to get the required result.

Syntax:

plot + scale_x_log10() / scale_y_log10()

Note: Using this method only the data plots are converted into the log scale. The axis tick marks and label remain the same.

Example:

Here is a basic scatter plot converted into the log10 scale x-axis by using the scale_x_log10() function.

R

# set seed 
set.seed(50000)  
  
# create sample data using rnorm function 
sample_data <- data.frame(x_axis_values = rnorm(1000, 700, 105), 
                   y_axis_values = rnorm(1000, 45, 200)) 
  
#load library ggplot2 
library("ggplot2") 
  
# draw scatter plot using ggplot() and geom_point() function 
# scale_x_log10() function converts the x-axis values to 
# log10 scale 
plot<- ggplot(sample_data, aes(x_axis_values, y_axis_values)) + 
                  geom_point() + scale_x_log10() 
  
# show plot 
plot
