如何将ggplot的符号和颜色用于LaTeX中的图形标题?

我正在写一篇论文,我正在使用R作为我的情节。期刊指南指出,情节的传说必须在数字标题中。所以我想知道是否有可能以及如何将R符号和颜色用于LaTeX的标题中?如何将ggplot的符号和颜色用于LaTeX中的图形标题?

此外,红色圆圈并未出现在已编译的文档中。

中的R

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"))

dev.off()

的LaTeX文档

\documentclass[10pt,a4paper, twocolumns]{article} 

\usepackage[utf8]{inputenc}

\usepackage[T1]{fontenc}

\usepackage{amsmath}

\usepackage{amsfonts}

\usepackage{amssymb}

\usepackage{graphicx}

\begin{document}

This is a test\par

%

\begin{figure}[htb]

\centering

\includegraphics{Figure1.pdf}

\caption{I want here the symbols and colors that were used in R}

\label{fig:figure1}

\end{figure}

\end{document}

任何帮助情节?

回答:

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查找符号。三角符号,可以发现这样的:
