我对 geom_ribbon 有疑问，我认为这是一个错误而不是功能。我想放大情节中“有趣”的部分，但我不希望 ggplot 仅仅因为整个事情不适合情节而排除任何内容。为此，我使用 coord_cartesian 来进行限制。它适用于线和点，可能还有许多其他东西（条形），但不适用于 geom_ribbon。这是一个例子：
# Load libraries
library(ggplot2)
# Create data:
set.seed(1234)
LineA=c(seq(1,20,0.1))
LineB=c(seq(1,25,0.1))
LineC=c(seq(1,19,0.1))
LineD=c(seq(1,60,0.1))
my_df=data.frame(Mean = c(sort(sample(LineA,40)),sort(sample(LineB,40)),sort(sample(LineC,40)),
sort(sample(LineD,40))))
my_df$Names=c(rep("Line-A",40),rep("Line-B",40),rep("Line-C",40),rep("Line-D",40))
my_df$SD=c(runif(n = 120, min = 1, max = 5),runif(n = 40, min = 1, max = 20))
my_df$Time=c(1:40,1:40,1:40,1:40)
my_df$Mean_low=my_df$Mean-my_df$SD
my_df$Mean_low[my_df$Mean_low<0]=0
my_df$Mean_hi=my_df$Mean+my_df$SD
head(my_df)
# Plot
# Ribbon visible:
ggplot(my_df, aes(x=Time, y=Mean)) + geom_line(aes(colour = Names), size = 1) +
geom_point(size = 2, aes(shape = Names, color = Names))+
geom_ribbon(aes(x = Time, y=NULL, ymin = Mean_low, ymax …
