I have a dataframe called crashes_deaths_injuries_TA_pop that looks like:

I am trying to show the data with a bar chart however, the scale of x-axis is messed up and I'm not sure how to . I know this must be easy but I am new to coding so I am struggling.

here is my code for the bar chart:

ggplot(crashes_deaths_injuries_TA_pop, aes(x = reorder(TA_name, Population), y = Population, fill = Population))  
  geom_col(alpha = 0.7)  
  scale_fill_distiller(palette = "Reds", direction = 1)  
  coord_flip()  
  labs(x = "", y = "Population", fill = "Population",
       title = "Populations of South Island TA's | 2018",
       caption = "Data: Census 2018, StatsNZ")  
  theme_minimal()  
  theme(legend.position = "none") 

I was also wondering how can you add like the population as a number at the end of each bar for each TA_name

CodePudding user response：

Use scale_y_continuous(breaks = ) to edit ticks of x axis of yours and use geom_text to add Population next to the bar chart. Here's an example.

ggplot(crashes_deaths_injuries_TA_pop, aes(x = reorder(TA_name, Population), y = Population, fill = Population))  
  geom_col(alpha = 0.7)  
  scale_fill_distiller(palette = "Reds", direction = 1)  
  coord_flip()  
  labs(x = "", y = "Population", fill = "Population",
       title = "Populations of South Island TA's | 2018",
       caption = "Data: Census 2018, StatsNZ")  
  theme_minimal()  
  theme(legend.position = "none")  
  scale_y_continuous(breaks = seq(0, 5e05, 0.5e05))   geom_text(aes(label = Population, y = Population 0.18e05))
