浮动组合中图形标题的位置错误

这是我的代码：

\usemodule[tikz]
\usetikzlibrary{positioning,shapes}

\starttext
  \tikzset{
    cflow/.style={draw=black, ellipse, text centered, minimum width=1cm},
    arr/.style = {->,>=stealth},
  }
  \startfloatcombination[distance=10pt]
    \startplacetable[force,title={My Table}]
      \starttable[|l|l|l|l|l|l|l|l|l|l]
        \NC P \VL f1 \NC f2 \NC f3 \NC f4 \NC f5 \NC f6 \NC f7 \NC f8 \NC f9 \AR
        \HL \NC A \VL c \NC b \NC c \NC - \NC - \NC - \NC - \NC a \NC - \AR
      \stoptable
    \stopplacetable
    \startplacefigure[force,title={My Graph}]
      \starttikzpicture
        \node[cflow] (f1) {f1};
        \node[cflow,right=of f1] (f8) {f8};
        \node[cflow,right=of f8] (f2) {f2};
        \node[cflow,below=of f1] (f4) {f4};
        \node[cflow,below=of f8] (f6) {f6};
        \node[cflow,below=of f2] (f5) {f5};
        \node[cflow,below=of f4] (f9) {f9};
        \node[cflow,below=of f6] (f7) {f7};
        \node[cflow,below=of f5] (f3) {f3};

        \draw[arr] (f1) -- (f4);
        \draw[arr] (f1) -- (f6);
        \draw[arr] (f2) -- (f5);
        \draw[arr] (f3) -- (f7);
        \draw[arr] (f4) -- (f9);
        \draw[arr] (f6) to[bend left] (f7);
        \draw[arr] (f7) to[bend left] (f6);
        \draw[arr] (f8) -- (f2);
      \stoptikzpicture
    \stopplacefigure
  \stopfloatcombination
\stoptext

其结果是：

为什么第二个标题放错了位置？我该如何修复？

我不太清楚内部发生了什么，但你必须用 包裹住tikzpicture里面的内容framed。实际上，这样\hbox就足够了，但framed语义上更好。我猜这与 TeX 此时处于 vmode 状态有关，它只是将 包裹tikzpicture到宽度为 的 vbox 中\textwidth。

此外，的语法force是错误的，应该是location={force}。但是，在此设置下它不起作用，因此我将其删除。

\usemodule[tikz]
\usetikzlibrary{positioning,shapes}

\starttext
  \tikzset{
    cflow/.style={draw=black, ellipse, text centered, minimum width=1cm},
    arr/.style = {->,>=stealth},
  }
  \startfloatcombination[distance=10pt]
    \startplacetable[title={My Table}]
      \starttable[|l|l|l|l|l|l|l|l|l|l]
        \NC P \VL f1 \NC f2 \NC f3 \NC f4 \NC f5 \NC f6 \NC f7 \NC f8 \NC f9 \AR
        \HL \NC A \VL c \NC b \NC c \NC - \NC - \NC - \NC - \NC a \NC - \AR
      \stoptable
    \stopplacetable
    \startplacefigure[title={My Graph}]
      \startframed[frame=off,offset=none]
        \starttikzpicture
          \node[cflow] (f1) {f1};
          \node[cflow,right=of f1] (f8) {f8};
          \node[cflow,right=of f8] (f2) {f2};
          \node[cflow,below=of f1] (f4) {f4};
          \node[cflow,below=of f8] (f6) {f6};
          \node[cflow,below=of f2] (f5) {f5};
          \node[cflow,below=of f4] (f9) {f9};
          \node[cflow,below=of f6] (f7) {f7};
          \node[cflow,below=of f5] (f3) {f3};

          \draw[arr] (f1) -- (f4);
          \draw[arr] (f1) -- (f6);
          \draw[arr] (f2) -- (f5);
          \draw[arr] (f3) -- (f7);
          \draw[arr] (f4) -- (f9);
          \draw[arr] (f6) to[bend left] (f7);
          \draw[arr] (f7) to[bend left] (f6);
          \draw[arr] (f8) -- (f2);
        \stoptikzpicture
      \stopframed
    \stopplacefigure
  \stopfloatcombination
\stoptext

在此处输入图片描述

如果你不想每次处于 vmode 时都小心地将 包装tikzpicture进去，你也可以调整 的定义。framed\start...\stoptikzpicture

\unprotect

\let\old_start_tikz_picture=\starttikzpicture
\let\old_stop_tikz_picture =\stoptikzpicture

\newconditional\tikz_picture_started_in_vmode

\starttexdefinition unexpanded starttikzpicture
  \setfalse\tikz_picture_started_in_vmode
  \ifvmode
    \startframed[frame=off,offset=none]
    \settrue\tikz_picture_started_in_vmode
  \fi
  \old_start_tikz_picture
\stoptexdefinition

\starttexdefinition unexpanded stoptikzpicture
  \old_stop_tikz_picture
