邊權重和節點標籤

我正在嘗試繪製帶有節點和邊權重的圖表。這是我到目前為止所做的事情。我已經放置了節點名稱。但我想將節點權重放在圓圈下方。我也想添加邊緣權重。我不知道如何放置邊緣標籤。這是我目前的程式碼。

\begin{tikzpicture}[transform shape]
\node[vertex][](t) at (2, 0) {$ \omega_{i} $};
\node[vertex][](r1) at (1, 2) {$ r^{\omega_{i}}_{1} $};
\node[vertex][](r2) at (3, 2) {$ r^{\omega_{i}}_{2} $};
\node[vertex][](q1) at (0,-2) {$ q^{\omega_{i}}_{1} $};
\node[vertex][](q2) at (2,-2) {$ q^{\omega_{i}}_{2} $};
\node[vertex][](q3) at (4,-2) {$ q^{\omega_{i}}_{2} $};
\begin{scope}[every path/.style={-, dashed}]
       \draw (t) -- (q1);
       \draw (t) -- (q2); 
       \draw (t) -- (q3);

       \draw (t) -- (r1);
       \draw (t) -- (r2);
\end{scope}
\begin{scope}[every path/.style={-}]
       \draw (r1) -- (q1);
       \draw (r1) -- (q2);
       \draw (r1) -- (q3);
       \draw (r2) -- (q1);
       \draw (r2) -- (q2);
       \draw (r2) -- (q3);
\end{scope} 
\end{tikzpicture}

您可以新增這樣的邊緣標籤：\draw (t) -- node [anchor=south] {$p_1$} (q1)。您必須嘗試一下才能正確設定錨點（選擇north、south west等，以查看效果）。您可能需要查看的其他參數是inner sep（標籤周圍的空白）和pos（決定標籤將出現在邊緣的位置）。

\node[vertex, label=below:$10$](t) at (2, 0) {$ \omega_{i} $};新增節點權重可以透過（另請注意，您不需要額外的）來完成[]。

幹得好：

\documentclass{article}
\usepackage{tikz}

\begin{document}
\tikzstyle{vertex}=[circle, draw]
\begin{tikzpicture}[transform shape]
\node[vertex, label=right:$1$](t) at (4, 0) {$ \omega_{i} $};
\node[vertex, label=above:$2$](r1) at (2, 2) {$ r^{\omega_{i}}_{1} $};
\node[vertex, label=above:$3$](r2) at (6, 2) {$ r^{\omega_{i}}_{2} $};
\node[vertex, label=below:$4$](q1) at (0,-2) {$ q^{\omega_{i}}_{1} $};
\node[vertex, label=below:$5$](q2) at (4,-2) {$ q^{\omega_{i}}_{2} $};
\node[vertex, label=below:$6$](q3) at (8,-2) {$ q^{\omega_{i}}_{2} $};
\begin{scope}[every path/.style={-, dashed}, every node/.style={inner sep=1pt}]
       \draw (t) -- node [anchor=north west] {$1$} (q1);
       \draw (t) -- node [anchor=west]  {$2$} (q2); 
       \draw (t) -- node [anchor=north east] {$3$} (q3);

       \draw (t) -- node [anchor=north east] {$4$} (r1);
       \draw (t) -- node [anchor=north west] {$5$} (r2);
\end{scope}
\begin{scope}[every path/.style={-}, every node/.style={inner sep=1pt}]
       \draw (r1) -- node [anchor=east] {$6$} (q1);
       \draw (r1) -- node [pos=0.15, anchor=north east] {$7$} (q2);
       \draw (r1) -- node [pos=0.15, anchor=south west] {$8$} (q3);
       \draw (r2) -- node [pos=0.15, anchor=south east] {$9$} (q1);
       \draw (r2) -- node [pos=0.15, anchor=north west] {$10$} (q2);
       \draw (r2) -- node [anchor=west] {$11$} (q3);
\end{scope} 
\end{tikzpicture}
\end{document}

如果您希望邊緣標籤自動旋轉，您可以使用sloped：

\documentclass{article}
\usepackage{tikz}

\begin{document}
\tikzstyle{vertex}=[circle, draw]
\begin{tikzpicture}[transform shape]
\node[vertex, label=right:$1$](t) at (4, 0) {$ \omega_{i} $};
\node[vertex, label=above:$2$](r1) at (2, 2) {$ r^{\omega_{i}}_{1} $};
\node[vertex, label=above:$3$](r2) at (6, 2) {$ r^{\omega_{i}}_{2} $};
\node[vertex, label=below:$4$](q1) at (0,-2) {$ q^{\omega_{i}}_{1} $};
\node[vertex, label=below:$5$](q2) at (4,-2) {$ q^{\omega_{i}}_{2} $};
\node[vertex, label=below:$6$](q3) at (8,-2) {$ q^{\omega_{i}}_{2} $};
\begin{scope}[every path/.style={-, dashed}, every node/.style={sloped, inner sep=1pt}]
       \draw (t) -- node [anchor=north] {$1$} (q1);
       \draw (t) -- node [anchor=south]  {$2$} (q2); 
       \draw (t) -- node [anchor=north] {$3$} (q3);

       \draw (t) -- node [anchor=north] {$4$} (r1);
       \draw (t) -- node [anchor=north] {$5$} (r2);
\end{scope}
\begin{scope}[every path/.style={-}, every node/.style={sloped, inner sep=1pt}]
       \draw (r1) -- node [anchor=south] {$6$} (q1);
       \draw (r1) -- node [pos=0.15, anchor=north] {$7$} (q2);
       \draw (r1) -- node [pos=0.15, anchor=south] {$8$} (q3);
       \draw (r2) -- node [pos=0.15, anchor=south] {$9$} (q1);
       \draw (r2) -- node [pos=0.15, anchor=north] {$10$} (q2);
       \draw (r2) -- node [anchor=south] {$11$} (q3);
\end{scope} 
\end{tikzpicture}
\end{document}
