我用过tkz-euclide，我得到了这个

但我希望长度文本位于行之间，如第一张图所示。这是我的代码

\begin{figure}
\centering
\begin{tikzpicture}[vect/.style={<->,
        shorten >=1pt,>=latex},vect1/.style={|<->|,
        shorten >=1pt,>=latex},scale=1]
    \tkzDefPoint(0,0){O}
    \tkzDefPoint(9,0){Z}
    \tkzDefPoint(1,0){A}
    \tkzDefPoint(8,0){D}
    \tkzDefPoint(2.3,0){B}
    \tkzDefPoint(5,0){C}
    \tkzDefPoint(1,0.5){A1}
    \tkzDefPoint(8,0.5){D1}
    \tkzDefPoint(1,-0.6){A2}
    \tkzDefPoint(5,-0.6){C2}
    \tkzDefPoint(2.3,-1.2){B2}
    \tkzDefPoint(8,-1.2){D2}
    \tkzDrawSegments[thick,vect](O,Z)
    \tkzDrawPoints[color=blue](A,B,C,D)
    \tkzLabelPoints[below](A,B,C,D)
    \tkzDrawSegments[vect1](A1,D1 A2,C2 B2,D2)
    \tkzLabelSegments[above](A1,D1){24 cm}
    \tkzLabelSegments[below](A2,C2){15 cm}
    \tkzLabelSegments[below](B2,D2){17 cm}

和TikZ

\documentclass[10pt]{article} 
\usepackage{tkz-euclide}


\begin{document} 
\begin{figure}
\centering
\begin{tikzpicture}[vect/.style={<->,
        shorten >=1pt,>=latex},vect1/.style={|<->|,
        shorten >=1pt,>=latex},scale=1]
    \tkzDefPoint(0,0){O}
    \tkzDefPoint(9,0){Z}
    \tkzDefPoint(1,0){A}
    \tkzDefPoint(8,0){D}
    \tkzDefPoint(2.3,0){B}
    \tkzDefPoint(5,0){C}
    \tkzDefPoint(1,0.5){A1}
    \tkzDefPoint(8,0.5){D1}
    \tkzDefPoint(1,-0.6){A2}
    \tkzDefPoint(5,-0.6){C2}
    \tkzDefPoint(2.3,-1.2){B2}
    \tkzDefPoint(8,-1.2){D2}
    \tkzDrawSegments[thick,vect](O,Z)
    \tkzDrawPoints[color=blue](A,B,C,D)
    \tkzLabelPoints[below](A,B,C,D)
    \tkzDrawSegments[vect1](A1,D1 A2,C2 B2,D2)
    % \tkzLabelSegments[center](A1,D1){24 cm}
    % \tkzLabelSegments[below](A2,C2){15 cm}
    % \tkzLabelSegments[below](B2,D2){17 cm}
    \path (A1) -- (D1) node[fill=white,midway]{24 cm};
\end{tikzpicture}
\end{figure}

附有tkz-euclide文档第127和128页。

\documentclass{standalone} 
\usepackage{tkz-euclide}
\begin{document} 
\begin{tikzpicture}[scale=2]
\pgfkeys{/pgf/number format/.cd,fixed,precision=2}
\tkzDefPoint(0,0){A}

这很容易实现pstricks：

\documentclass[border=6pt, svgnames]{standalone}
\usepackage{pst-eucl}

\begin{document}

\begin{pspicture}(0,-2.5)(9,1.5)
\psset{arrowinset=0}
\pstGeonode[PointSymbol=*, PosAngle=-90, linecolor=DodgerBlue](1,0){A}(2.3,0){B}(5,0){C}(8,0){D}
\pstLineAB[nodesepA=-1, nodesepB=-1, arrows=<->]{A}{D}
\psset{arrows=|<->|}
\ncline[offset=0.8cm]{A}{D}\ncput*{24 cm}
\ncline[offset=-0.8cm]{A}{C}\ncput*{15 cm}
\ncline[offset=-1.3cm]{B}{D}\ncput*{17 cm}
\end{pspicture}

\end{document}

我会这样解决

\begin{tikzpicture}[vect/.style={<->,
        shorten >=1pt,>=latex},vect1/.style={|<->|,
        shorten >=1pt,>=latex},scale=1]

    \tkzDefPoint(0,0){O}
    \tkzDefPoint(9,0){Z}
    \tkzDefPoint(1,0){A}
    \tkzDefPoint(8,0){D}
    \tkzDefPoint(2.3,0){B}
    \tkzDefPoint(5,0){C}
    \tkzDefPoint(1,0.5){A1}
    \tkzDefPoint(8,0.5){D1}
    \tkzDefPoint(1,-0.6){A2}
    \tkzDefPoint(5,-0.6){C2}
    \tkzDefPoint(2.3,-1.2){B2}
    \tkzDefPoint(8,-1.2){D2}
    \tkzDrawSegments[thick,vect](O,Z)
    \tkzDrawPoints[color=blue](A,B,C,D)
    \tkzLabelPoints[below](A,B,C,D)
    \tkzDrawSegments[vect1](A1,D1 A2,C2 B2,D2)
    \path[coordinate] (A1) -- (D1) coordinate[pos=.5](F);
    \node[fill=white] at (F) {24cm};
    \tkzLabelSegments[below](A2,C2){15 cm}
    \tkzLabelSegments[below](B2,D2){17 cm}
\end{tikzpicture}

答案4

为什么我们不使用简单的 TikZ？

在此处输入图片描述

\documentclass[tikz,border=5mm]{standalone}
\begin{document}
\begin{tikzpicture}[>=stealth]
\draw[<->,thick] (-1,0)-- 
(0,0) coordinate (A) node[below]{$A$}-- 
(5,0) coordinate (B) node[below]{$B$}--(6,0);
\foreach \p in {A,B} \fill[red] (\p) circle(1.5pt);
\draw[|<->|,gray] 
([shift={(0,.5)}]A)--([shift={(0,.5)}]B)
node[midway,fill=white,text=blue,scale=.8]{5 cm};
\end{tikzpicture}
\end{document}
