我会给你一个关于数据的想法，我认为这样应该更容易理解我想要实现的目标。
复制品：
ID <- c(1, 1, 2, 3, 3, 3)
cat <- c("Others", "Others", "Population", "Percentage", "Percentage", "Percentage")
logT <- c(2.7, 2.9, 1.5, 4.3, 3.7, 3.3)
m <- c(1.7, 1.9, 1.1, 4.8, 3.2, 3.5)
aggr <- c("median", "median", "geometric mean", "mean", "mean", "mean")
over.under <- c("overestimation", "overestimation", "underestimation", "underestimation", "underestimation", "underestimation")
data <- cbind(ID, cat, logT, m, aggr, over.under)
data <- data.frame(data)
data$ID <- as.numeric(data$ID)
data$logT<- as.numeric(data$logT)
data$m<- as.numeric(data$m)
代码：
Fig <- data %>% ggplot(aes(x = logT, y = m, …
