r - 如何将图片插入到 ggplot 图中的每个单独的条中

Question

我正在尝试比较不同 NBA 新秀的不同统计数据，并且我认为如果我可以像 r/dataisbeautiful graphs 那样在图表末尾添加球员的脸部，图表看起来会很棒。 。我的代码目前是这样的:

a3 %>%
  ggplot(aes(x = reorder(Player,
                         PPM),
             y = PPM)) +
  geom_bar(stat = "identity",
           aes(fill = Player)) +
  geom_text(aes(label = PPM), size = 3, position = position_dodge(width = 1),
            hjust = -0.1) +
  coord_flip() +
  theme_minimal() +
  xlab("Player") +
  ylab("Points Per Minute") +
  theme(legend.position = "none")

这就是我的图表当前的样子

您没有提供代表，所以我需要弥补一些。我可能会这样做。

data <- tibble(
  count = c(5, 6, 6, 4, 2, 3),
  animal = c("giraffe", "elephant", "horse", "bird", "turtle", "dog"),
  image = list(
    image_read_svg("http://steveharoz.com/research/isotype/icons/giraffe.svg"),
    image_read_svg("http://steveharoz.com/research/isotype/icons/elephant.svg"),
    image_read_svg("http://steveharoz.com/research/isotype/icons/horse.svg"),
    image_read_svg("http://steveharoz.com/research/isotype/icons/bird.svg"),
    image_read_svg("http://steveharoz.com/research/isotype/icons/turtle.svg"),
    image_read_svg("http://steveharoz.com/research/isotype/icons/dog.svg")
  )
)

ggplot(data, aes(animal, count, fill = animal, image = image)) +
  geom_isotype_col(
    img_height = grid::unit(1, "null"), img_width = NULL,
    ncol = 1, nrow = 1, hjust = 1, vjust = 0.5
  ) +
  coord_flip() +
  guides(fill = "none") +
  theme_minimal()
