我正在尝试将 3d 数据绘制为 2d（请参阅附图
）。
在 Tex（或 Matlab）中，这可能吗？（通常，这是以图例的形式完成的，但是，当不允许使用颜色时，我必须像附图中那样绘制它）。如果可以，请提供任何提示。提前谢谢
这也是数据的一个示例：

请注意 Z 对于每一列来说都是恒定的
答案1
您可以使用contourplot。首先，在 MATLAB 中准备数据：
[reshape(X,[],1), reshape(Y,[],1), reshape(Z,[],1)];
然后，你就可以在 TeX 中使用这些数据了：
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
xticklabel style={/pgf/number format/.cd, fixed, precision=2},
yticklabel style={/pgf/number format/.cd, fixed, precision=3},
]
\addplot[
colormap={onlyblack}{gray(0cm)=(0); gray(1cm)=(0)},
contour prepared,
contour/contour label style={/pgf/number format/.cd, fixed, precision=2},
contour/label distance={1000pt}, % use big number to get one label per contour

得出以下结果：
注意：我认为有一个拼写错误，并将您的其中一点从 更改.01809045226131为1.01809045226131。
答案2
如果你使用包matlab2tikz由 Mathworks 提供，将最新的图导出为任意文件名：
matlab2tikz('my3d_plot.tikz');
请记住，您必须下载此功能（并将其保存在活动文件夹中以供评估）。此外，此功能为每个图生成一个名为的文件，my3d_plot-n.png其中n代表第 n 个图/子图。
3D 绘图
例如使用 matlab 绘图函数
imagesc(DATA);
colorbar('location','southoutside')
该函数具有设置颜色限制和颜色主题的选项。这些选项在 mathworks 的主页。
保存存档
将文件保存'my3d_plot.tikz'在与处理过的 latex 文件相同的目录中，否则文件内的路径my3d_plot.tikz将指向错误的目录。
Latex 文件
类似下面的 MWE 应该可以实现这一点：
\documentclass{article}
\usepackage{pgfplots}
\usepackage{graphicx}
\pgfplotsset{compat=newest}
\pgfplotsset{plot coordinates/math parser=false}
\begin{document}
\input{my3d_plot.tikz}
\end{document}
这回答了您的问题吗？还是有关要绘制的另一个特征的问题？
