多面餅圖ggplot2-不完整，僅線條

Question

dat <- data.frame(table(total$Name, total$Color))
# adds the Count column
names(dat) <- c("Name","Color","Count")

NAME    COLOR    Count
John    Green    1
Joe     Green    12
Jane    Green    32  
Jill    Green    34
John    Blue     2
Joe     Blue     4
Jane    Blue     23  
Jill    Blue     12
John    Red      4
Joe     Red      42
Jane    Red      36  
Jill    Red      15 

如何按名稱創建一組多面餅圖？ 當我嘗試：

e <- ggplot(data=dat, aes(x=Name, fill=Color)) 
e + geom_bar(position = "fill") + 
facet_wrap(~Name) +
coord_polar()

它產生的餅圖只是線條。 任何人都可以識別錯誤或提供任何解決方案嗎？

Answer 1

1. 將aes中的x設置為靜態值。 我選擇了0。
2. 將theta =“ y”添加to coord_polar`以告訴它以角度使用哪個軸。
3. 添加scale_fill_identity()因為您已將顏色直接映射到填充值中。
4. 添加了theme_void()來擺脫令人困惑的軸等。

library(tidyverse)

dat <- tribble(~Name,~Color,~Count,
"John",    "Green",    1,
"Joe" ,   "Green",   12,
"Jane",    "Green",    32, 
"Jill",    "Green",    34,
"John",    "Blue",   2,
"Joe" ,   "Blue",   4,
"Jane",    "Blue",   23,  
"Jill",    "Blue",   12,
"John",    "Red",   4,
"Joe" ,   "Red",   42,
"Jane",    "Red",   36,  
"Jill",    "Red",   15)

ggplot(data=dat, aes(x = 0, y = Count, fill=Color)) + 
  geom_col(position = "fill") + 
  facet_wrap(~Name) +
  coord_polar(theta = "y") +
  scale_fill_identity() +
  theme_void()
