How to plot geom_bar without showing multiple lines

Question

I am trying to do a bar plot, however, is printing multiple lines on each bar. I understand that I might have to aggregate but if I do I need to retain the original columns because I need to fill by some of them. Question: How can I get rid of the horizontal lines on each bar? Example below:

x <- structure(list(SampleDate = structure(c(19738, 19744, 19744, 
19746, 19746, 19747, 19749, 19753, 19754, 19758, 19758, 19758, 
19758, 19758, 19759, 19759, 19759, 19760, 19761, 19761, 19762, 
19763, 19765, 19765, 19766, 19766, 19766, 19767, 19767, 19767, 
19770, 19770, 19771, 19771), class = "Date"), Survey = c("early", 
"late", "late", "late", "late", "late", "early", "late", "late", 
"late", "late", "late", "late", "late", "late", "early", "early", 
"early", "early", "early", "late", "late", "late", "late", "late", 
"late", "late", "late", "early", "early", "early", "early", "early", 
"early"), LifeStage = c("Adult", "Adult", "Adult", "Adult", "Adult", 
"Adult", "Adult", "Adult", "Adult", "Adult", "Juvenile", "Adult", 
"Adult", "Adult", "Adult", "Adult", "Adult", "unkLifeStage", 
"Juvenile", "unkLifeStage", "Adult", "Adult", "Adult", "unkLifeStage", 
"Adult", "unkLifeStage", "Adult", "unkLifeStage", "unkLifeStage", 
"Adult", "unkLifeStage", "Juvenile", "unkLifeStage", "Juvenile"
), numb_fish = c(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 
1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1), year = c(2024, 
2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 
2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 
2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024, 2024
), month = c(1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 
2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2)), row.names = c(NA, 
-34L), class = c("tbl_df", "tbl", "data.frame"))
x
x$SampleDate <- as.Date(x$SampleDate,"%m/%d/%Y")
x <- x |> mutate(month = floor_date(SampleDate, "month"))

ggplot(x, aes(x = month, y = numb_fish, fill = LifeStage)) +
  geom_bar(stat = "identity", color = 'black') +
  labs(title = "Monthly Data",
       y = "Total") + 
  scale_x_date(date_breaks = "1 month", date_labels = "%b-%y") 

Below is the graphic that I am getting. Need to get rid of those annoying lines..

Answer 1

Your numb_fish is all 1, so we can count(.) it ... but in case that number could be something else, we will summarize to get something more useful:

library(dplyr)
summarize(x, .by = c(month, LifeStage), n = sum(numb_fish)) |>
  ggplot(aes(month, n, fill = LifeStage)) +
  geom_bar(stat = "identity", color = "black") +
  labs(title = "Monthly Data", y = "Total") +
  scale_x_date(date_breaks = "1 month", date_labels = "%b-%y")
