geom_bar issue in ggplot2 with xlim()

Question

[rj.rezwan]

Hi, I am using very simple data to make a bar plot in ggplot2. but when I use the xlim() ggplot2 in R. It makes the plot wut without bars in it. Could someone help me or guide why the bars are not being produced by ggplot2

here is the code

library(ggplot2)
library(readxl)

mapping <- read_excel("/Users/tariqr/Desktop/haplotypecalling/mapping_percentage.xlsx", sheet = "Sheet3", col_names = TRUE)
head(mapping)
varieties percentage
  <chr>          <dbl>
1 beauty_9        99.1
2 beauty_8        99.1
3 beauty_7        99.0
4 beauty_64       99.2
5 beauty_63       96.9
6 beauty_62       99.2



ggplot(mapping, aes(x = percentage, y = varieties)) +
  geom_bar(stat = "identity", fill = "#99FF00", color = "purple") +
  geom_text(aes(label = sprintf("%.2f%%", percentage)), 
            hjust = -0.2, size = 3, color = "black") +  # Add text labels
  theme(axis.text.x = element_text(angle = 90, hjust = 1)) +
  labs(title = "Mapping Percentage", x = "Mapping", y = "Varieties") +
  scale_x_continuous(breaks = seq(96.5, 100, by = 0.5), 
                     labels = paste0(seq(96.5, 100, by = 0.5), "%")) +
  xlim(96.5, 100)

Can someone suggest how to bring the bars in the plot. here is the plot without bars

I will be grateful.
