Question

library(tidyverse)
library(geomtextpath)
plot_data_2 <- data.frame(category=c('品类A','品类B','品类C','品类D'),
                          amount=c(1,6,4,7))

plot_data_2 %>% ggplot(aes(x=1,y=amount,fill=category))+
  geom_col()+geom_textpath(position = position_stack(vjust=0.5),
                           aes(label=category))+
  coord_polar()
