本文介绍了如何突出两条线之间的区域? ggplot的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有包含变量的数据框,它是conf。间隔

 时间x x.upper x.lower 
1 1.00 0.91 1.11
2 1.03 0.92 1.13
3 1.03 0.95 1.17
2 1.06 0.90 1.13



ggplot 它:

  library(ggplot2)
ggplot(data = df,aes (time,x))+
geom_line(aes(y = x.upper),color ='red')+
geom_line(aes(y = x.lower),color ='blue') +
geom_line()

我想突出显示红线和蓝线之间的区域,到 geom_smooth()函数。

  ggplot(data = df,aes(time,x))+ 
geom_ribbon(aes(x = time ,ymax = x.upper,ymin = x.lower),fill =pink,alpha = .5)+
geom_line(aes(y = x.upper),color ='red')+
geom_line(aes(y = x.lower),color ='blue')+
geom_line()

I have data frame containing variable and it's conf. interval

time x     x.upper   x.lower
   1 1.00     0.91      1.11
   2 1.03     0.92      1.13
   3 1.03     0.95      1.17
   2 1.06     0.90      1.13

I ggplot it:

library(ggplot2)
ggplot(data = df,aes(time,x))+
    geom_line(aes(y = x.upper), colour = 'red') +
    geom_line(aes(y = x.lower), colour = 'blue')+
    geom_line()

I want to highlight area between red and blue lines, smth similar to geom_smooth() function. How can I do it?

解决方案

A geom_ribbon is exactly what you need

ggplot(data = df,aes(time,x))+
    geom_ribbon(aes(x=time, ymax=x.upper, ymin=x.lower), fill="pink", alpha=.5) +
    geom_line(aes(y = x.upper), colour = 'red') +
    geom_line(aes(y = x.lower), colour = 'blue')+
    geom_line()
