我想将 pgfplot 中的“nodes near coord”的字体大小以及 y 刻度标签更改为 1pt（不用担心，这只是理论上的兴趣）。我发现
\setbeamerfont{MyMiniSize}{size*={1.00}{1.00}}
\setbeamerfont{MyMiniSize2}{family=\sffamily,series=\mdseries,size={\fontsize{1}{1}}}
\pgfplotsset{every tick label/.append style={font=\usebeamerfont{MyMiniSize}}}
\pgfplotsset{every node near coord/.append style={font=\usebeamerfont{MyMiniSize}}}
应该这样做，但显然没有任何变化。原因可能是什么？
这是我的 MWE（我知道，有太多的坐标不能称之为“最小”，但它应该可以解释为什么需要这么小的字体大小）

答案1
您的 MWE 远非最小；我用很多更简单的文件。
该.log文件显示了您需要知道的所有内容：
LaTeX Font Warning: Font shape `T1/cmss/m/n' in size <1> not available (Font) size <5> substituted on input line 74.
编译 MWE 时会出现许多这样的警告。标准字体不适用于这么小的设计尺寸，因此会使用最小的可用字体。
用来fix-cm告诉 LaTeX 该字体是可扩展的，我们可以看到它运行良好：
\RequirePackage{fix-cm}
\documentclass{beamer}
\setbeamerfont{MyMiniSize}{size*={1.00}{1.00}}
\setbeamerfont{MyMiniSize2}{family=\sffamily,series=\mdseries,size={\fontsize{1}{1}}}
\begin{document}
\begin{frame}[t]{Banana}
{\usebeamerfont{MyMiniSize} Test\par}
{\usebeamerfont{MyMiniSize2} Test2\par}
\end{frame}
\end{document}
话虽如此，但我真的不推荐这样做，因为没人会看到这些数字。观众可能会认为投影仪的镜头上有污渍，或者投影屏幕上有苍蝇，或者诸如此类的东西。它看起来是这样的，用一个正常标题大小的香蕉作为比例：
并且，在整个幻灯片的上下文中：
