问题描述

我在 Excel 中制作了 double-y-axis 图表。在Excel中只需要基本技能。我想要做的是使用 R 中的 ggplot2 库来复制此图表。 b
$ b



我已经完成了这项工作,但是我需要绘制Response 2nd-y-axis





附上可重复使用的代码:

 #数据生成
年份< - c(2014,2015,2016)
响应<-c(1000,1100,1200)
费率<-c(0.75,0.42,0.80)

df< - data.frame(Year,Response,Rate)

#Chart
library(ggplot2)

ggplot(df)+
geom_bar(aes(x = Year,y = Response),stat =identity,fill =tan1,color =sienna3)+
geom_line (aes(x = Year,y = Rate),stat =identity)+
geom_text(aes(label = Rate,x = Year,y = Rate),color =black)+
geom_text(aes(label = Response,x = Year,y = 0.9 * Response),color =black)


Rate * max(df $ Response) Rate > c $ c>并修改响应文本的 0.9 比例。

其次,通过 scale_y_continuous(sec.axis = ...)


  ggplot(df) + 
geom_bar(aes(x = Year,y = Response),stat =identity,fill =tan1,color =sienna3)+
geom_line(aes(x = Year,y = Rate * max(df $ Response)),stat =identity)+
geom_text(aes(label = Rate,x = Year,y = Rate * max(df $ Response)),color =black )+
geom_text(aes(label = Response,x = Year,y = 0.95 * Response),color =black)+
scale_y_continuous(sec.axis = sec_axis(〜。/ max df $ Response)))

其中:b / b
$ b


I have double-y-axis chart made in Excel. In Excel it requires only basic skills. What I'd like to do is to replicate this chart using the ggplot2 library in R.

I have already done this, but I need to plot Response on 2nd-y-axis.

I enclose reproducible code I've used:

#Data generation
Year <- c(2014, 2015, 2016)
Response <- c(1000, 1100, 1200)
Rate <- c(0.75, 0.42, 0.80)

df <- data.frame(Year, Response, Rate)

#Chart
library(ggplot2)

ggplot(df)  + 
  geom_bar(aes(x=Year, y=Response),stat="identity", fill="tan1", colour="sienna3")+
  geom_line(aes(x=Year, y=Rate),stat="identity")+
  geom_text(aes(label=Rate, x=Year, y=Rate), colour="black")+
  geom_text(aes(label=Response, x=Year, y=0.9*Response), colour="black")

解决方案

First, scale Rate by Rate*max(df$Response) and modify the 0.9 scale of Response text.

Second, include a second axis via scale_y_continuous(sec.axis=...):

ggplot(df)  + 
    geom_bar(aes(x=Year, y=Response),stat="identity", fill="tan1", colour="sienna3")+
    geom_line(aes(x=Year, y=Rate*max(df$Response)),stat="identity")+
    geom_text(aes(label=Rate, x=Year, y=Rate*max(df$Response)), colour="black")+
    geom_text(aes(label=Response, x=Year, y=0.95*Response), colour="black")+
    scale_y_continuous(sec.axis = sec_axis(~./max(df$Response)))

Which yields:
