ggplot2在docker的rstudio-server中无法正确显示汉字 [英] ggplot2 doesn't show Chinese character properly in rstudio-server in docker

问题描述

我尝试使用ggplot2绘制带有中文标题的图表，但以正方形显示Unicode.

我尝试了以下一些命令

 石英(family ='STKaiti')par(family ='STKaiti')plot(1，xlab =你好"，family =海蒂SC Light") 

并使用额外字体"字体将我的ubuntu字体加载到R中显示的字符图仍然是Unicode正方形.我想正确显示中文单词.

仍然，我不知道该如何称呼这种话."Unicode in a square"是我所能描述的最好的.

解决方案

尝试

I try to use ggplot2 to plot a chart with the Chinese title but shows Unicode in a square.

I've tried some following command

quartz(family='STKaiti')
par(family='STKaiti')
plot(1, xlab = "你好", family = "Heiti SC Light")

and use "extrafont" font to load my ubuntu fonts into R The characters plot shows are still Unicode in a square. I want to show the Chinese word properly.

Still, I have no idea how to call this kind of words. "Unicode in a square" is the best I can describe.

解决方案

Try the showtext package, which was designed for this.

Sample code:

library(ggplot2)
library(showtext)
showtext_auto()

p = ggplot(NULL, aes(x = 1, y = 1)) + ylim(0.8, 1.2) +
    annotate("text", 1, 1, size = 15, label = "你好，世界") +
    xlab("坐标轴") +
    theme_bw(base_family = "wqy-microhei", base_size = 24)

quartz()
print(p)
