我已经能够使用 gnuplot 绘制 3D 图，但无论我做什么，都无法使用 pfgplots 或 tikz 绘制图。有时我会收到“尺寸太大”错误，有时我会得到一个空图。我尝试限制 x 或 y 或 z 域，但仍然得到一个空图。有什么想法吗？
\documentclass[tikz]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis} [yticklabels=\empty, xticklabels=\empty,zticklabels=\empty]
\addplot3+ [only marks,mark size=1, blue] table {dat.txt};
\end{axis}
\end{tikzpicture}
\end{document}

似乎pgfplots无法自动设置 x 轴限制。手动设置xmin=804774, xmax=804775有效。
\documentclass[tikz, margin=10pt]{standalone}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
\begin{axis}[yticklabels=\empty, xticklabels=\empty, zticklabels=\empty, xmin=804774, xmax=804775]
\addplot3+ [only marks,mark size=1,blue] table[header=false] {dat.txt};
\end{axis}
\end{tikzpicture}
\end{document}
