在 ggplot2 箱线图旁边显示基本汇总统计信息

Question

Is it possible to display the summary statistics next to the boxplot like:

throu<-structure(list(case_id = c("WC4132791", "WC4130879", "WC4128064", 
"WC4121569", "WC4121568", "WC4130112", "WC4131829", "WC4130841", 
"WC4130306", "WC4130417", "WC4124741", "WC4130114", "WC4131990", 
"WC4121986", "WC4128062", "WC4122478", "WC4130337", "WC4125822", 
"WC4127231", "WC4124761", "WC4129398", "WC4131040", "WC4123072", 
"WC4131822", "WC4120712", "WC4121978", "WC4130110", "WC4123522", 
"WC4130307", "WC4122643", "WC4130383", "WC4122248", "WC4122299",

"WC4123345", "WC4130314", "WC4127722", "WC4129978", "WC4131838", 
"WC4130812", "WC4126953"), throughput_time = c(134.283333333333, 
93.0756944444445, 83.5340277777778, 67.7833333333333, 65.3069444444444,

49.7375, 49.0916666666667, 46.3069444444444, 45.30625, 45.2451388888889,

)), row.names = c(NA, 50L), class = "data.frame")

I also have already extracted those in a separate dataframe:

quarts<- structure(list(min = 0, q1 = 7.1515625, median = 11.4881944444444, 
    mean = 12.3112423835125, q3 = 14.8456597222222, max = 93.0756944444445, 
    st_dev = 6.72704434885421, iqr = 7.69409722222222), class = "data.frame", row.names = c(NA, 
-1L))




# A really basic boxplot.
ggplot(throu, aes( y=throughput_time)) + 
  geom_boxplot(fill="slateblue", alpha=0.2,width=0.05) +
  xlim(-0.1, 0.1) +
  xlab("")+ylab("Case duration in days")+ theme_classic()+ 
  theme(axis.ticks.x = element_blank(),
        axis.text.x = element_blank())

Answer 1

You could do this using annotate

ggplot(throu, aes( y=throughput_time)) + 
  geom_boxplot(fill="slateblue", alpha=0.2, width=0.05) +
  annotate(geom = 'text', x = 0.05, y = 60, hjust = 0, color = 'gray50',
           label = paste(names(quarts), collapse = '\n')) +
  annotate(geom = 'text', x = 0.07, y = 60, hjust = 0,
           label = paste(round(unlist(quarts), 3), collapse = '\n')) +
  xlim(-0.1, 0.1) +
  xlab("")+
  ylab("Case duration in days")+ 
  theme_classic()+ 
  theme(axis.ticks.x = element_blank(),
        axis.text.x = element_blank())
