如何将ggplot的符号和颜色用于LaTeX中的图形标题？

Posted 2021-04-07

我正在写一篇论文，我正在用R作为我的情节。期刊指南说，情节的传说必须在图标题中。所以我想知道是否可以以及如何将R符号和颜色用于LaTeX中的标题？

此外，红色圆圈没有出现在编译文档中。

在R中绘制

library(ggplot2)

A <- seq(0, 10, by = 1)
B <- seq(0, 20, by = 2)
C <- seq(0, 30, by = 3)

DF <- data.frame(A, B, C)

pdf(
  file = "Figure1.pdf",
  width = 8/2.54,
  height = 5/2.54,
  pointsize = 8
)
ggplot(data = DF) +
  geom_point(aes(x = 0:10, y = A, color = "A", shape = "A")) +
  geom_point(aes(x = 0:10, y = B, color = "B", shape = "B")) +
  geom_point(aes(x = 0:10, y = C, color = "C", shape = "C")) +
  scale_shape_manual(name = "Legend", values = c(0, 1, 2)) +
  scale_color_manual(name = "Legend", values = c("black", "red", "blue"))

任何帮助？

答案

我只是在LaTeX中找到相应的符号并手动添加着色。我可以推荐detexify来寻找符号。三角符号可以这样找到：
