我希望根据文件 data.txt 中提供的轮廓坐标绘制 3D 表面。以下代码按预期工作。
\usepackage{pgfplots}
\pgfplotsset{compat = newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}[view={0}{160},
xlabel={$x$},
ylabel={$y$},
zlabel={$z$}]
\addplot3[green, fill] table[x={X}, y={Y} , z={Z}] {data.txt};
\end{axis}
\end{tikzpicture}
\end{document}
其结果是：
现在我想用非常量颜色进行填充。具体来说，我想用渐变进行填充，其中颜色由数据的 y 值决定。如何实现？
为了完整起见，这是 data.txt 文件：

您可能只想在更好的图像程序中制作图形，然后截取最终结果的屏幕截图并将\includegraphics其放入您的 TeX 文件中。
