将多个 TikZ 树与其他节点对齐

将多个 TikZ 树与其他节点对齐

这个问题直接关系到将 TikZ 树与其他节点对齐这是我前段时间问的。当我问这个问题的时候，我并没有意识到对齐多棵树和对齐一棵树是不一样的。事实上，Dmitry F. Volosnykh 提出的答案要求先创建树，然后再创建它必须与之对齐的其他节点。因此，这个问题应该命名为“将一棵 TikZ 树与其他节点对齐”。

但是，当你需要对齐多棵树时，它们不能同时出现在第一位。有些树必须出现在其他树之后。

我已经完成了上一个问题中给出的示例，作为我需要解决的完整示例，并揭示了我所谈论的问题。请注意，用于包含三棵树的三个拟合节点处于正确的位置。但所有树木都位于相同的坐标上，并叠加在“变换”框上。

这是我得到的图形：在此处输入图片描述

当然，我希望能够将它们放置在各自的盒子中。

以下是代码：

\documentclass{article}

\usepackage{tikz,nicefrac,amsmath,pifont,graphicx}
\usetikzlibrary{arrows,snakes,backgrounds,patterns,matrix,shapes,fit,calc,positioning,trees}

\usepackage[graphics,tightpage,active]{preview}
\PreviewEnvironment{tikzpicture}
\newlength{\imagewidth}
\newlength{\imagescale}

\graphicspath{{/Users/ludo/Documents/cours/xml/slides/gfx/}{/Users/ludo/Documents/cours/xml/slides/src/gfx/}}

\begin{document}

\begin{tikzpicture}[
     >=stealth', semithick, node distance=1cm, level distance=7mm, level/.style={sibling distance=10mm/#1},
    block/.style = {draw, rectangle, rounded corners, minimum height=1cm},
    every node/.style={circle, draw, fill=none, anchor=north}
]
\node  [block] (transfo) {\parbox{2.5cm}{\centering transformation}};

\node (source tree root) {}
    child { node {} }
    child { node {}
        child { node {} }
        child { node {} }
    };
\node (source tree) [draw, rectangle, fit=(source tree root) (source tree root-1) (source tree root-2-2), left=of transfo] {};

\node [block] (source document) [left=of source tree] {\parbox{2cm}{\centering source document}};

\node (stylesheet tree root) {}
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {}
        child { node {} }
        child { node {} }
    };
\node (stylesheet tree) [draw, rectangle, fit=(stylesheet tree root) (stylesheet tree root-1-1) (stylesheet tree root-2-2), above=of transfo] {};

\node [block] (stylesheet document) [above=of stylesheet tree] {stylesheet};

\node (result tree root) {}
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {}
        child { node {} }
        child { node {} }
    };
\node (result tree) [draw, rectangle, fit=(result tree root) (result tree root-1-1) (result tree root-2-2), right=of transfo] {};

\node [block] (result document) [right=of result tree] {\parbox{2cm}{\centering result document}};

\begin{scope}[shorten >=1pt]
\draw [->] (source document) edge (source tree);
\draw [->] (source tree) edge (transfo);
\draw [->] (transfo) edge (result tree);
\draw [->] (result tree) edge (result document);
\draw [->] (stylesheet document) edge (stylesheet tree);
\draw [->] (stylesheet tree) edge (transfo);
\end{scope}
\end{tikzpicture}


\end{document}

答案1

有两个问题：一是您的树都没有放置在特定坐标上。因此它们都以 (0,0) 为根，使它们重叠。另一个问题是，left=of transfo树边界节点的定位选项（等）会覆盖它们的拟合选项。

我能想到两种解决方法：

  1. 将树代码放在\tikz{}树边界节点内的命令中，如source tree。您必须将选项传递给tikzpicture要保留的更大环境。命名\tikzstyles 可能会有所帮助。然后仅使用树边界节点的定位选项。

  2. 将树的根放置在其中\node (source tree root) at (someplace)，然后仅使用树边界节点的拟合选项。

我无法决定你应该采用哪种方法。我认为前者，因为它有助于定位树边界节点。

答案2

\tikz{}使用Matthew Leingang 上述命令的第一种方法的改编示例是：

\documentclass{article}

\usepackage{tikz,nicefrac,amsmath,pifont,graphicx}
\usetikzlibrary{arrows,snakes,backgrounds,patterns,matrix,shapes,fit,calc,positioning,trees}

\usepackage[graphics,tightpage,active]{preview}
\PreviewEnvironment{tikzpicture}
\newlength{\imagewidth}
\newlength{\imagescale}

\graphicspath{{/Users/ludo/Documents/cours/xml/slides/gfx/}{/Users/ludo/Documents/cours/xml/slides/src/gfx/}}

\begin{document}

\begin{tikzpicture}[
     >=stealth', semithick, node distance=1cm, level distance=7mm, level/.style={sibling distance=10mm/#1},
    block/.style = {draw, rectangle, rounded corners, minimum height=1cm},
    every node/.style={circle, draw, fill=none, anchor=north},
]
%\node [outer sep=0pt, inner sep=0pt, draw=none] (transfo) {\includegraphics[width=1.5cm]{xslt1.0/machinery.jpg}};
\node  [block] (transfo) {\parbox{2.5cm}{\centering transformation}};

\node (source tree) [draw=none, rectangle, left=of transfo] {\tikz{%
\node {}
    child { node {} }
    child { node {}
        child { node {} }
        child { node {} }
    };
}};

\node [block] (source document) [left=of source tree] {\parbox{2cm}{\centering source document}};

\node (stylesheet tree) [draw=none, rectangle, above=of transfo] {\tikz{%
\node {}
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {}
        child { node {} }
        child { node {} }
    };
}};

\node [block] (stylesheet document) [above=of stylesheet tree] {stylesheet};

\node (result tree) [draw=none, rectangle, right=of transfo] {\tikz{%
\node (result tree root) {}
    child { node {}
        child { node {} }
        child { node {} }
    }
    child { node {}
        child { node {} }
        child { node {} }
    };
}};

\node [block] (result document) [right=of result tree] {\parbox{2cm}{\centering result document}};

\begin{scope}[shorten >=1pt]
\draw [->] (source document) edge (source tree);
\draw [->] (source tree) edge (transfo);
\draw [->] (transfo) edge (result tree);
\draw [->] (result tree) edge (result document);
\draw [->] (stylesheet document) edge (stylesheet tree);
\draw [->] (stylesheet tree) edge (transfo);
\end{scope}
\end{tikzpicture}

\end{document}
