当我sin(x)在 gnuplot 中制作并通过 Lualatex 编译它时，它确实可以工作，但是当我在 gnuplot 中制作堆积条形图并执行相同操作时，它现在不起作用。我正在使用\input{filename.tex}包graphicx。免责声明 - 我是 gnuplot 的新手。这是源代码sin(x)：

可以正常工作。接下来是直方图的源代码，但不能正常工作：

我很无助，试图寻找解决方案近2天......我还有一些错误的截图。
这是直方图：
有效的测试文件

\setmainfont{Minion Pro}
\usepackage{amsmath}
\usepackage{unicode-math}

对于我的代码，它会打印这个，虽然它很窄......
