不带衬线的轴标签中的非斜体希腊字母(MacOS)

标签: r macos ggplot2 fonts typography

是否可以选择在R的轴标签中应用ggplotsans-serif来获得一个很好的非斜体希腊字母(在我的情况下为“ mu”)?

这是我走了多远: Overview of the hole plot

输出的缩放: Zoom picture of the mu

左“ mu”:如果我仔细看,它不合适:

  • 错误的font(我可以解决)
  • 错误的font大小

右“ mu”:

  • 刚刚好,但我需要它不是italic,因为它应该是一个单元

(提示:在R-Studio预览窗口中显示为非italic,但我需要PDF正确。)

以下是R代码:

library("ggplot2")

x <- seq(0,10,1)
y <- seq(0,1,0.1)
Data <- data.frame(x,y)

myPlot <- ggplot (Data, aes(x = x,y = y)) + 
geom_point() +
scale_x_continuous(expression(paste("[", mu, "m] and [µm]")))+
theme(text = element_text(size=12, family="sans")) +
theme_minimal(); myPlot

ggsave("Test.pdf", width = 16, height = 8, units ="cm", dpi = 1200)

更新I:sessionInfo()的输出仅在MacO而不是Windows上显示。

我正在使用Mac OS并遇到相同的问题。我通过将图像另存为.eps文件来解决此问题。在预览中打开.eps仍显示单位为斜体,但是在另一个图像编辑器中打开时,单位非斜体。
