我制作了以下图表：
使用以下代码（使用 XeLaTeX 编译）：
\documentclass[border=5pt]{standalone}
\usepackage[table]{xcolor} % more control over colors
\usepackage{tikz}
\usepackage{pgfplots}
\usepackage{pgfplotstable}
\usepackage{amsmath}
\usepackage{amssymb}
% fonts
\usepackage{mathspec}
\setmainfont{[opensans.ttf]}
\begin{document}
\begin{tikzpicture}
\pgfplotstableread[col sep=comma]{

xticklabel shift={-\pgfkeysvalueof{/pgfplots/axis x line shift}},
table/x expr = \coordindex,
x tick label style = {rotate=90},]
%
% done with the axis, now the plots
\addplot [black, fill, draw opacity = 0] table [y=2Q20] {\chart};
\addplot [red, fill, draw opacity = 0, nodes near coords] table [y=3Q20] {\chart};

\end{tikzpicture}
\end{document}
如你所见，我使用fontspecOpen Sans 作为我的字体（要下载opensans.ttf我使用的文件，请访问此图表的背面）。
但是，它仅适用于文本，而不适用于轴标签或节点。
我如何使用我选择的 otf/ttf 文件并使其也适用于所有这些文件？
答案1
轴标签在数学模式下排版，并且您没有声明数学字体。
