我想将下面代码中的直红线改为弯曲线

Question

我怎样才能创建如图所示的蜿蜒线条？

Answer 1

我无法使用阿拉伯字体的代码，所以我适应了欧洲字符。垂直线可以decorated用decoration库来表示TikZ，请咨询文档并使其符合您的口味。

关于title，我认为最好使用fonttitle和coltitle选项，而不是将所有内容都包含在title选项中。您也可以使用before title或after title选项来包含\bccrayon。

在这个答案中，我只关注制作类似于波浪的东西。我甚至无法复制你的代码，因为我的旧编辑器无法处理特殊字符，对不起。complete sines是从这里。

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{decorations}
\pgfdeclaredecoration{complete sines}{initial}
{
    \state{initial}[
        width=+0pt,
        next state=sine,
        persistent precomputation={\pgfmathsetmacro\matchinglength{
            \pgfdecoratedinputsegmentlength / int(\pgfdecoratedinputsegmentlength/\pgfdecorationsegmentlength)}
            \setlength{\pgfdecorationsegmentlength}{\matchinglength pt}
        }] {}
    \state{sine}[width=\pgfdecorationsegmentlength]{
        \pgfpathsine{\pgfpoint{0.25\pgfdecorationsegmentlength}{0.5\pgfdecorationsegmentamplitude}}
        \pgfpathcosine{\pgfpoint{0.25\pgfdecorationsegmentlength}{-0.5\pgfdecorationsegmentamplitude}}
        \pgfpathsine{\pgfpoint{0.25\pgfdecorationsegmentlength}{-0.5\pgfdecorationsegmentamplitude}}
        \pgfpathcosine{\pgfpoint{0.25\pgfdecorationsegmentlength}{0.5\pgfdecorationsegmentamplitude}}
}
    \state{final}{}
}

\begin{document}
\tikzset{fancy sines/.style={decoration={
            complete sines,
            segment length=3mm,
            amplitude=1mm
        },decorate,to path={
      (\tikztostart) -- (\tikztotarget) \tikztonodes
    },
    execute at begin to={\foreach \X in {1,...,5}
    {\draw[decorate,#1]
    ([xshift=\X*\pgflinewidth/sqrt(1.9),yshift=-\X*\pgflinewidth/sqrt(1.9)]\tikztostart) 
    -- ([xshift=\X*\pgflinewidth/sqrt(1.9),yshift=-\X*\pgflinewidth/sqrt(1.9)]\tikztotarget);}}}
}
\begin{tikzpicture}    
\draw[red,fancy sines=red] (0,0) to (0,-3);
\end{tikzpicture}
\end{document}
