左对齐ggplot标题

Question

我使用R包ggtext来"plot align“(最大左对齐)我的标题和副标题。我还想使用这些ggtext方法来“对齐”我的标题。

library(tidyverse)
library(ggtext)
ggplot(mpg, aes(cty, hwy)) + 
  geom_point() +
  theme(plot.title.position = "plot",
        plot.caption.position = "plot",
        plot.title = element_markdown(),
        plot.subtitle = element_markdown(),
        plot.caption = element_markdown()) +
  labs(title = "This is the title.", 
       subtitle = "This is the subtitile.", 
       caption = "This is the caption.")

你可能会注意到标题是右对齐的，而标题和副标题是“绘图对齐”的。

如何“打印对齐”我的标题？

Answer 1

这是可行的。基于@Ben评论。

library(tidyverse)
library(ggtext)
ggplot(mpg, aes(cty, hwy)) + 
  geom_point() +
  theme(plot.title.position = "plot",
        plot.caption.position = "plot",
        plot.title = element_markdown(),
        plot.subtitle = element_markdown(),
        plot.caption = element_markdown(hjust = 0)) +
  labs(title = "This is the title.", 
       subtitle = "This is the subtitile.", 
       caption = "This is the caption.")

Answer 2

为了其他人的利益，您可以通过以下方式在ggplot2中左对齐标题：

library(ggplot2)

ggplot(mpg, aes(cty, hwy)) + 
  geom_point() +
  theme(plot.caption = element_text(hjust = 0)) + # set the left align here
  labs(title = "This is the title.", 
       subtitle = "This is the subtitile.", 
       caption = "This is the caption.")
