If you are talking about the use of scientific notation on your y-axis, you can add a labels = argument taking a labeling function from the scales package to format the labels to your liking.
library(tidyverse)
n <- 1000
set.seed(123)
x <- runif(n, 1, 15)
y <- exp(x) + rnorm(length(x))
df <- data.frame(x = x, y = y)
ggplot(df) +
geom_line(aes(x = x, y = y)) +
scale_y_log10()
