架构的标题或说明

Question

我可以给这个架构添加标题吗？如果我使用，\caption{\textbf{\label {}The multilevel of the abstraction}}我有 pb。谢谢

\documentclass[tikz,border=3.14mm]{standalone}
    \usepackage[edges]{forest}
    \begin{document}
    \begin{forest}
    for tree={draw,edge={-latex},parent anchor=south,align=left}
    [Ontological models and languages\\ 
    for mathematical knowledge management\\ 
    on the Semantic Web 
     [Terminological Ressources\\ and Symbolic Notation\\ for Mathematical domain
      [Terminological Ressources
       [Vocabularies
        [The Online Encyclopedia\\ of Integer Sequences]
       ]
       [pft112
        [pft1121]
        [pft1122]
       ]  
      ]
      [pft12
       [pft121
        [pft1211]
       ]
       [pft122
        [pft1221]
       ]  
       [pft123
        [pft1231]
       ]  
      ]
     ]
     [pft2
      [pft21
       [pft211]
       [pft212]  
      ]
      [pft22]
     ]
    ]
    \end{forest}
    \end{document}

Answer 1

我很乐意删除它，但您需要将其放在table或figure环境中才能使用\caption。并且您可能不会standalone为此使用该类。

\documentclass{article}
\usepackage[edges]{forest}
\begin{document}
\begin{table}
\centering
\caption{\textbf{The multilevel of the abstraction.}\label{fig:tree}}
\begin{forest}
for tree={draw,edge={-latex},parent anchor=south,align=left,
}
[Ontological models and languages\\ 
for mathematical knowledge management\\ 
on the Semantic Web 
 [Terminological Ressources\\ and Symbolic Notation\\ for Mathematical domain
  [Terminological Ressources
   [Vocabularies
    [The Online Encyclopedia\\ of Integer Sequences]
   ]
   [pft112
    [pft1121]
    [pft1122]
   ]  
  ]
  [pft12
   [pft121
    [pft1211]
   ]
   [pft122
    [pft1221]
   ]  
   [pft123
    [pft1231]
   ]  
  ]
 ]
 [pft2
  [pft21
   [pft211]
   [pft212]  
  ]
  [pft22]
 ]
]
\end{forest}
\end{table}
\end{document}

Answer 2

使用 caption 包的另一种方法：

\documentclass{article}
\usepackage{caption}
\usepackage[edges]{forest}
\begin{document}
\begin{forest}
for tree={draw,edge={-latex},parent anchor=south,align=left}
[Ontological models and languages\\ 
for mathematical knowledge management\\ 
on the Semantic Web 
 [Terminological Ressources\\ and Symbolic Notation\\ for Mathematical domain
  [Terminological Ressources
   [Vocabularies
    [The Online Encyclopedia\\ of Integer Sequences]
   ]
   [pft112
    [pft1121]
    [pft1122]
   ]  
  ]
  [pft12
   [pft121
    [pft1211]
   ]
   [pft122
    [pft1221]
   ]  
   [pft123
    [pft1231]
   ]  
  ]
 ]
 [pft2
  [pft21
   [pft211]
   [pft212]  
  ]
  [pft22]
 ]
]
\end{forest}
\captionof{figure}{foo}
\end{document}
