在 tikz 绘图中定位文本

全部，

我想将文本放置在 tikz 图片中，使其不干扰所绘制的线条。我是 tikz 新手，所以请耐心等待我的编码。

这是我的代码

\begin{tikzpicture} % STYLES \tikzset{
    ellips/.style={ellipse, minimum width=100pt,
    align=center,node distance=3cm,fill=black!10,inner sep=5pt,text width=2.5cm,minimum 
    height=2.0cm,>=stealth'} }

\node [ellips](Choices) {Strategic Choices}; 
\node [above=2cm of Choices](dummy) {}; 
\node [ellips, force, left=1.5cm of dummy] (Institutions) {Institutions}; 
\node [ellips, force, right=1.5cm of dummy] (Organisations) {Organisations};

% Draw the links between  
\path[<->,thick]   
     (Choices) edge node[anchor=center, text width=3.5cm, left, midway] {Industry conditions and firm-specific resources}  (Institutions)   
     (Choices) edge node[anchor=center, text width=3.5cm, right, midway] {Formal and informal constraints} (Organisations)  
     (Institutions) edge  node [midway, below] {interaction} node[midway, above] {Dynamic} (Organisations);

\end{tikzpicture}

结果如下

放置auto尝试猜测路径中节点的最佳定位，以便节点的文本不会与路径重叠。

通常，auto到 会将文本放在路径遍历方向的左侧。因此，对于从(Institutions)到 的路径(Organization)，auto将把文本放在上方。对于从(Choices)到 的路径(Institutions)，它将使用，而对于从到 的below left路径，它将使用。(Choices)(Organizations)above left

由于最后一个不是我们想要的，我们可以从(Organizations)到绘制最后一条路径(Choices)，以将文本放在所需的位置：

%In the preamble
\usetikzlibrary{shapes.geometric,arrows,positioning}

\begin{tikzpicture}[force/.style={},
    ellips/.style={ellipse, minimum width=100pt,
    align=center,node distance=3cm,fill=black!10,inner sep=5pt,text width=2.5cm,minimum 
    height=2.0cm,>=stealth'}
]

\node [ellips](Choices) {Strategic Choices}; 
\node [above=2cm of Choices](dummy) {}; 
\node [ellips, force, left=1.5cm of dummy] (Institutions) {Institutions}; 
\node [ellips, force, right=1.5cm of dummy] (Organisations) {Organisations};

% Draw the links between  
\path[<->,thick]   
     (Choices) edge node[anchor=center, text width=3.5cm, auto, midway] {Industry conditions and firm-specific resources}  (Institutions)   
     (Organisations) edge node[anchor=center, text width=3.5cm, auto, midway] {Formal and informal constraints} (Choices)  
     (Institutions) edge  node [midway, below] {interaction} node[above, midway] {Dynamic} (Organisations);
\end{tikzpicture}

您可以使用below left和below right。但请确保您的 MWE 是可编译的。它缺少许多必需的项目。

%In the preamble
% \usetikzlibrary{shapes.geometric,arrows,positioning}

\begin{tikzpicture}[force/.style={},
    ellips/.style={ellipse, minimum width=100pt,
    align=center,node distance=3cm,fill=black!10,inner sep=5pt,text width=2.5cm,minimum 
    height=2.0cm,>=stealth'}
]

\node [ellips](Choices) {Strategic Choices}; 
\node [above=2cm of Choices](dummy) {}; 
\node [ellips, force, left=1.5cm of dummy] (Institutions) {Institutions}; 
\node [ellips, force, right=1.5cm of dummy] (Organisations) {Organisations};

% Draw the links between  
\path[<->,thick]   
     (Choices) edge node[anchor=center, text width=3.5cm, below left, midway] {Industry conditions and firm-specific resources}  (Institutions)   
     (Choices) edge node[anchor=center, text width=3.5cm, below right, midway] {Formal and informal constraints} (Organisations)  
     (Institutions) edge  node [midway, below] {interaction} node[midway, above] {Dynamic} (Organisations);

\end{tikzpicture}
