Question

我不想在情节之外添加图例，而是想在图中添加诸如“分位数1”，“分位数10”等名称作为标签。

ggplot() + 
  geom_line(data=df.quants, aes(x=xvars, y=q01), color="black", size =0.5) +
  geom_line(data=df.quants, aes(x=xvars, y=q10), color="black", size =0.7) +
  geom_line(data=df.quants, aes(x=xvars, y=q25), color="black", size =1) +
  geom_line(data=df.quants, aes(x=xvars, y=q50), color="black", size =1.2) +
  geom_line(data=df.quants, aes(x=xvars, y=q75), color="black", size =1) +
  geom_line(data=df.quants, aes(x=xvars, y=q90), color="black", size =0.7) +
  geom_line(data=df.quants, aes(x=xvars, y=q99), color="black", size =0.5) +
  geom_ribbon(data=df.quants,aes(x=xvars,ymin=q25,ymax=q75),alpha=0.8)+
  geom_ribbon(data=df.quants,aes(x=xvars,ymin=q10,ymax=q25),alpha=0.5)+
  geom_ribbon(data=df.quants,aes(x=xvars,ymin=q75,ymax=q90),alpha=0.5)+
  geom_ribbon(data=df.quants,aes(x=xvars,ymin=q01,ymax=q10),alpha=0.2)+
  geom_ribbon(data=df.quants,aes(x=xvars,ymin=q90,ymax=q99),alpha=0.2)+
  theme_bw()+
  ggtitle("Q")+
  ggsave("save.png")

如何在这两种情况中的一种或两种情况下在图上添加标签：

在行尾（例如https://stackoverflow.com/a/37696769/3942806）
将鼠标悬停在左侧（https://stackoverflow.com/a/37672486/3942806）

dput（df.quants）

Answer 1

您应该尝试使用directlabels包。这是一个例子：

library(tidyverse)
library(directlabels)
df.quants %>% 
  gather(var,val,-1) %>% 
  ggplot(aes(xvars,val,fill=var)) + 
  geom_area(position="identity", alpha = .5) +
  geom_line() + 
  scale_fill_grey(guide="none") + 
  geom_dl(aes(label=var), method="last.points")

确保浏览其文档，因为还有更多选项。

您可以扩展该方法以使用自定义标签，线宽，填充等。一种方法可能是：

labs <- setNames(c("G", "F", "E", "D", "C", "B", "A"), c("q99", "q90", "q75", "q50", "q25", "q10", "q01"))
df.quants %>% 
  rev %>%
  gather(var,val,-xvars,factor_key=TRUE) %>% 
  ggplot(aes(xvars,val,fill=var)) + 
  geom_area(position="identity") +
  geom_line(aes(size=var)) + 
  scale_fill_manual(values = c(grey.colors(3,.9,.3), grey.colors(4)), guide="none") + 
  scale_size_manual(values = c(1:3,4:1), guide="none") + 
  geom_dl(aes(label=labs[var]), method="last.points")

如何在geom线上添加标签？
