Horizonal axis labels not showing on ggplot 2

This looks like it refers to the same data as Brant posted here.

Brant: In the code block you posted, the second half of the code overrides the first half — could remove the first half, meaning the half ends at "Step 1"?

Also, a reprex would help, and for this topic, aggregate data would be good. Could run the following code and post the output?

library(tidyverse)
data <- read.csv("fifteenminuteintervaldata.csv")
data |> 
  separate_wider_delim(
    cols = Date, 
    names = c("year", "month", "day"), 
    delim = '-', 
    cols_remove = F) |> 
  group_by(year, month) |> 
  summarise(
    Precipitation = sum(Precipitation), 
    Discharge = sum(Discharge)
  ) |> 
  dput()
