是否有 R 函数可以调整条形图的轴比例？

Question

我有一个名为 crashes_deaths_injuries_TA_pop 的数据框，它看起来像：

TA_name	Population
Gore	34466
Buller	444444
Cluth	34455

我正在尝试用条形图显示数据，但是 x 轴的比例混乱了，我不知道该怎么做。我知道这一定很简单，但我是编码新手，所以我很挣扎。

这是我的条形图代码：

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")

我还想知道如何在每个条的末尾为每个 TA_name

添加像人口一样的数字

使用 scale_y_continuous(breaks = ) 编辑您的 x 轴刻度，并使用 geom_text 在条形图旁边添加 Population。这是一个例子。

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))

Is there an R function to adjust scale in the axis for a barchart?
