如何将图片插入到ggplot图表的每个单独的栏中 [英] How to insert pictures into each individual bar in a ggplot graph

问题描述

我正在尝试比较不同统计数据的不同NBA新秀，并且我认为如果我可以在图的末尾添加球员的面孔，例如

I'm trying to compare different NBA rookies across different stats, and I thought the graph would look great if I could add the player's face at the end of the graph like in the r/dataisbeautiful graphs. My code is currently this:

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")

这是我的图形当前的外观

This is what my graph currently looks like

推荐答案

您没有提供reprex，所以我需要做些补充.我大概会这样.

You didn't provide a reprex, so I need to make something up. I would probably do it like this.

library(tidyverse)
library(ggtextures)
library(magick)
#> Linking to ImageMagick 6.9.9.39
#> Enabled features: cairo, fontconfig, freetype, lcms, pango, rsvg, webp
#> Disabled features: fftw, ghostscript, x11

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()
