数据集中的 3D 线图的 PGFPlots 颜色图不起作用

Question

viridis我正在尝试通过诸如或 之类的颜色图为路径着色，从而使我的 3D 图着色jet。

我没有在我的代码中看到这个问题：

梅威瑟：

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{colorbrewer}
\begin{document}

\pgfplotsset{colormap name=viridis}
    
    \begin{tikzpicture}
        \begin{axis}[% 
            minor tick num = 1,
            width=0.5\textwidth, 
            height=0.58\textwidth, 
            view={20}{20},
            no markers,
            line width=1pt,
            colormap/viridis
        ]
            \addplot3+[mesh/ordering=colwise, shader=interp] table[x=X,y=Y,z=Z,col sep=comma] {M_vec_t_konst_B_3D.csv};
        \end{axis}
    \end{tikzpicture}   
\end{document}

文件内容的一部分如下所示：

只需将您的情节重写为

\addplot3+[mesh] table[x=X,y=Y,z=Z,col sep=comma] {M_vec_t_konst_B_3D.csv};

它应该可以工作。

\documentclass[border=5mm]{standalone}
\usepackage{pgfplots}
\usepgfplotslibrary{colorbrewer}
\pgfplotsset{compat=1.18}
\begin{document}

\pgfplotsset{colormap name=viridis}

    \begin{tikzpicture}
        \begin{axis}[% 
            minor tick num = 1,
            width=0.5\textwidth, 
            height=0.58\textwidth, 
            view={20}{20},
            no markers,
            line width=1pt,
            colormap/viridis]
            \addplot3+[mesh, shader=interp] 
                 table[x=X,y=Y,z=Z,col sep=comma] 
                 {M_vec_t_konst_B_3D.csv};
        \end{axis}
    \end{tikzpicture}   
\end{document}
