A figura de um cubo (ou gráfico 3D), junto com uma imagem externa, é mostrada abaixo (e seu código éaqui). Estou tentando usar linhas tracejadas em vez de linhas sólidas nesta figura. Eu verifiquei esses links,link2,link3, elink4, mas preciso de ajuda para resolver esse problema.
\documentclass{standalone}
\usepackage{pgfplots}
\usetikzlibrary{3d,calc}
\begin{document}
\begin{tikzpicture}
\begin{axis}[
enlargelimits=false,
axis on top,
axis equal image,
xmin=0,xmax=4,
ymin=-1,ymax=1,
zmin=-1,zmax=1,
ylabel=$X$,zlabel=$Y$, %xlabel=$Z$,
view={-20}{30},
xtick={0, 4},
ticks = none,
clip = false,
]
\draw [black,dashed]
(axis cs:?) -- (axis cs:?) % ???
(axis cs:?) -- (axis cs:?);
\path (axis cs:0,0,0) coordinate (O) (axis cs:1,0,0) coordinate (X)
(axis cs:0,1,0) coordinate (Y) (axis cs:0,0,1) coordinate (Z)
(axis cs:4,0,0) coordinate (P)
[x={($(O)-(X)$)},y={($(O)-(Y)$)},z={($(Z)-(O)$)},
canvas is yz plane at x=0,transform shape]
(P) node{\includegraphics[width=2cm,height=2cm]{example-image-duck}};
\path (axis cs:0,0,0) coordinate (O) (axis cs:1,0,0) coordinate (X)
(axis cs:0,1,0) coordinate (Y) (axis cs:0,0,1) coordinate (Z)
(axis cs:0,0,0) coordinate (P)
[x={($(O)-(X)$)},y={($(O)-(Y)$)},z={($(Z)-(O)$)},

(P) node{\includegraphics[width=2cm,height=2cm]{example-image-duck}};
%\draw[black, <->] ([xshift =-0.09cm] axis description cs:0, 0.2) -- node[left] {} ([xshift =-0.1cm] axis description cs:0, 0.66) node[font=\scriptsize, midway, left=-1mm] {\fontsize{6.5}{6.5}\selectfont$y$};
%\draw[black, <->] ([xshift =-.14cm] axis description cs:0.01, 0.19) -- node[left] {} ([xshift =-.39cm] axis description cs:0.35,- 0.01)node[font=\scriptsize, midway,below] {\fontsize{6.5}{6.5}\selectfont$x$};
\end{axis}
\end{tikzpicture}

Não estou muito claro o que você está tentando fazer ou como tudo o que você tentou não funcionou, mas talvez algo assim ...
No entanto, existem zero cubos nesta resposta.
