从ggplot中删除y标签

Question

我想结合3 ggplot直方图。为此，我使用gridExtra包。因为所有图都在一行中，我想从右边的2个图中删除y标题和比例。

我一如既往地编写相同的代码，但它没有用。你们知道什么可能是个问题吗？我的代码：

plot1 <- ggplot(testing, aes(x=residualtotal))+
  geom_histogram(aes(y = ..density..), binwidth = 100) + 
  geom_density(aes(y = ..density..*(2)))+
  xlab("Residuals Model 1 [MW]")+
  theme(panel.background=element_rect(fill = "white") )+
  theme_minimal()
plot2 <- ggplot(testing, aes(x=residualtotal1))+
  geom_histogram(aes(y = ..density..), binwidth = 100) + 
  geom_density(aes(y = ..density..*(2)))+
  xlab("Residuals Model 2 [MW]")+
  theme(axis.text.y = element_blank(), axis.title.y = element_blank(), axis.ticks.y = element_blank(), panel.background=element_rect(fill = "white") )+
  theme_minimal()
plot3 <- ggplot(testing, aes(x=residualtotal2))+
  geom_histogram(aes(y = ..density..), binwidth = 100) + 
  geom_density(aes(y = ..density..*(2)))+
  xlab("Residuals Model 3 [MW]")+
  theme(axis.text.y = element_blank(), axis.title.y = element_blank(), axis.ticks.y = element_blank(), panel.background=element_rect(fill = "white") )+
  theme_minimal()
grid.arrange(plot1, plot2, plot3, ncol = 3, nrow=1)

我的数据集示例。

Answer 1

我认为您要找的是count并将+ ylab(NULL)移到theme()之后。我还为theme_minimal()添加了宽度规格，因为最左边的数字的宽度需要更宽，以便为y标题提供空间。

您的代码将是

grid.arrange

另一种方法：

library(tidyverse)

res_trans <- c(`residualtotal`="Residuals Model 1 [MW]",
               `residualtotal1`="Residuals Model 2 [MW]",
               `residualtotal2`="Residuals Model 3 [MW]")

select(testing, starts_with("resid")) %>% 
  gather(which_resid, value) %>% 
  mutate(label=res_trans[which_resid]) %>% 
  ggplot(aes(x=value, group=label)) +
  geom_histogram(aes(y = ..density..), binwidth = 100) + 
  geom_density(aes(y = ..density..*(2))) +
  facet_wrap(~label, ncol=3) +
  labs(x=NULL, y=NULL) +
  theme_minimal() +
  theme(panel.background=element_rect(fill = "white"))
