我正在研究一篇 elseiver 文章，我使用 matlab2tikz 导出一个 matlab 图形，我的问题是我无法更改 .tex 文件中的字体大小。
实际上，我有以下输出
我想减小轴、图例和标题的字体大小。
例如，对于左图，我有以下 .tex 文件

请问，有人能帮我改善图形吗？
答案1
style字体大小可以在各个绘图元素的设置中修改（此处xlabel、ylabel和）。 无需重复完整代码，以下是一些示例修改title：legend
xlabel style={font=\tiny\bfseries\color{white!15!black}},
ylabel style={font=\tiny\bfseries\color{white!15!black}},
title style={font=\small\bfseries},
legend style={font=\scriptsize, at={(0.97,0.03)}, anchor=south east, legend cell align=left, align=left, draw=white!15!black}
结果：
尺寸名称（\scriptsize等\tiny）可以在以下位置找到，例如，https://en.wikibooks.org/wiki/LaTeX/Fonts#Sizing_text。
