How to use scale_x_continuous() function with trans argument In R Language
We can convert the axis data into the desired log scale using the scale_x_continous() function. We pass the desired log scale as argument trans and the data is transformed according to that log scale in the ggplot2 plot.
Syntax:
plot + scale_x_continous( trans ) / scale_y_continous( trans )
Parameter:
- trans: determine the type of transformation given axis will go through.
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 scale_x_continuous function with trans argument as log10.
R
#load library ggplot2 library ( "ggplot2" ) # 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)) # draw scatter plot using ggplot() #and geom_point() function plot<- ggplot (sample_data, aes (x_axis_values, y_axis_values)) + geom_point () # scale_x_continuous #with trans argument transforms axis data to log scale plot<- plot + scale_x_continuous (trans = "log10" ) # show plot plot |
Output:
