ggplot2中繪圖設定x軸、y軸名稱距離框線的距離

001、基礎繪圖

library(ggplot2)#匯入ggplot包

ggplot(data = mtcars,         
       aes(x = wt, y = mpg, 
           colour = factor(cyl))) +  
  geom_point() +
  theme_bw()                    ## 基礎繪圖

002、設定x軸名稱與框線的距離

a、設定為5

library(ggplot2)#匯入ggplot包

ggplot(data = mtcars,         
       aes(x = wt, y = mpg, 
           colour = factor(cyl))) +  
  geom_point() +
  theme_bw() +
  theme(axis.title.x = element_text(vjust = 5))     ## 設定x軸名稱與框線的距離，vertical設定為5

b、設定為-3

library(ggplot2)#匯入ggplot包

ggplot(data = mtcars,         
       aes(x = wt, y = mpg, 
           colour = factor(cyl))) +  
  geom_point() +
  theme_bw() +
  theme(axis.title.x = element_text(vjust = -3))     ## 設定為-3

004、測試y軸

a、設定為5

library(ggplot2)#匯入ggplot包

ggplot(data = mtcars,         
       aes(x = wt, y = mpg, 
           colour = factor(cyl))) +  
  geom_point() +
  theme_bw() +
  theme(axis.title.y = element_text(vjust = 5))      ## 設定為5

b、設定為-5

library(ggplot2)#匯入ggplot包

ggplot(data = mtcars,         
       aes(x = wt, y = mpg, 
           colour = factor(cyl))) +  
  geom_point() +
  theme_bw() +
  theme(axis.title.y = element_text(vjust = -5))     ## 設定為-5
