在coord_polar上标注和缩放

Question

我想使用coord_polar通过一个简单的条形图来可视化我的数据框。我正在尝试复制此屏幕截图：

这是我的尝试：

p <- ggplot(data=df, aes(x=Month, y=Percent)) + 
   geom_col(aes(fill= Month ), width = 0.87 )+
  coord_polar()+
  labs(title="some title ", 
       subtitle="% of total number of something",
       x="", 
       y="",
       caption="Reaserch")+
  theme_minimal(10) +
  theme(legend.position = "none",
        text=element_text(family="Courier"),
        plot.title=element_text(size=12, hjust=0.2, face='bold'),
        plot.subtitle=element_text(size=11, hjust=0.2),
        axis.text.x = element_text(size=12, hjust=0.1, face='bold'),
        axis.title.x = element_blank(),
        panel.grid.minor = element_blank(),
        axis.ticks.y = element_blank())

结果

我想删除背景网格和左上轴，并显示饼图中每个记录的月份和值（例如8月68％）+在哪里定义color = "Yellow"的正确位置？

# reproducible sample data
df <- tibble::tribble(
       ~Month, ~Percent,
    "Jan",    68,
   "Feb",    68,
      "Mar",    68,
      "Apr",    68,
        "May",    68,
       "June",    65,
       "July",    52,
     "Aug",    60,
  "Sept",    68,
    "Oct",    68,
   "Nov",    68,
   "Dec",    68
  ) 

Answer 1

df$Month_label = paste0(df$Month, "\n", df$Percent, "%") %>% fct_inorder

ggplot(data=df, aes(x=Month_label, y=Percent)) + 
  geom_col(fill = "#ffc97b", width = 0.87 )+
  geom_text(aes(label = Month_label, y = Percent - 10)) +
  coord_polar()+
  labs(title="some title ", 
       subtitle="% of total number of something",
       x="", 
       y="",
       caption="Research")+
  theme_minimal(10) +
  theme(legend.position = "none",
        axis.text = element_blank(),
        text=element_text(family="Courier"),
        plot.title=element_text(size=12, hjust=0.2, face='bold'),
        plot.subtitle=element_text(size=11, hjust=0.2),
        panel.grid = element_blank(),
        axis.ticks.y = element_blank())
