我有以下格式的数据:
Section Env. Ar. Width Length
A 8.38 8.76 7 36
B 11.84 13.51 11 57
C 16.69 16.49 17 87
D 11.04 11.62 9 44
E 19.56 16.79 20 106
F 17.93 21.34 19 98
我需要在X轴上设置section
,在一个Y轴上设置Env.
和Ar.
,在另一个Y轴设置Width
和Length
,因为它有不同的规模。我知道如何使用ggplot
在一个Y轴上绘制它们,但我仍然坚持如我所提到的那样用两个不同的Y轴。任何帮助将不胜感激。
谢谢!

关于使用这个怎么样?
library(tidyverse)
d <- structure(list(Section = structure(1:6, .Label = c("A", "B",
"C", "D", "E", "F"), class = "factor"), Env. = c(8.38, 11.84,
16.69, 11.04, 19.56, 17.93), Ar. = c(8.76, 13.51, 16.49, 11.62,
16.79, 21.34), Width = c(7L, 11L, 17L, 9L, 20L, 19L), Length = c(36L,
57L, 87L, 44L, 106L, 98L)), .Names = c("Section", "Env.", "Ar.",
"Width", "Length"), class = "data.frame", row.names = c(NA, -6L))
d %>%
gather(key, value,-Section) %>%
ggplot(aes(Section, value, colour=key, group= key)) +
geom_line(size=1.1) + geom_point(size=4)+
scale_y_continuous(name="Env_Ar",
sec.axis = sec_axis(~., name = "Width_Length"))
您还可以尝试使用"free_y"
缩放的不同方面。这是IMO更清洁和优雅。
d %>%
gather(key, value,-Section) %>%
mutate(group=ifelse(key %in% c("Width","Length"), 2, 1)) %>%
ggplot(aes(Section, value, colour=key, group= key)) +
geom_line(size=1.1) + geom_point(size=4)+
facet_wrap(~group, scales = "free_y")
这里是右y轴的不同缩放(高10倍)的方法
d %>%
mutate(Width=Width*10,
Length=Length*10) %>%
gather(key, value,-Section) %>%
ggplot(aes(Section, value, colour=key, group= key)) +
geom_line(size=1.1) + geom_point(size=4)+
scale_y_continuous(name="Env_Ar",
sec.axis = sec_axis(~.*10, name = "Width_Length"))
