tikzpicture 上的圆圈问题

我对这个图形有疑问。

在此处输入图片描述

圆圈没有聚焦于相应的数字。例如，在第一行中，您应该聚焦于数字 1，但圆圈的顶部刚好触及它。以下是它应该看起来的样子： 在此处输入图片描述

使用包ycomb中的宏pgfplots：

\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{arrows.meta}

\begin{document}
    \begin{tikzpicture}
\begin{axis}[
    width=12cm, height=11cm,
    axis lines=center,
    grid={both},
    axis line style={thick,-Stealth},
    ycomb,  % <---
    xmin=-0.9,xmax=10.5,  ymax=1.08,ymin=-0.1,
    ytick={0,0.1,...,1.1},
    ylabel=$|n\cdot\omega_{0}|$, 
    xlabel={$f$},
    xlabel style={right}, % changed
    ticklabel style={circle, fill=orange!20, font=\footnotesize, 
                     minimum size=1.5em,inner sep=0pt},
    every axis plot post/.append style={ultra thick}    
  ]
    \addplot+[blue] coordinates {(0,1)};
    \addplot+[red, mark=*] coordinates {
                (1,0.6366) (2,0.3183) (3,0.2122) (4,0.1591) (5,0.1273)
                (6,0.1061) (7,0.0909) (8,0.0795) (9,0.0707) (10,0.0636)
                                       };
\end{axis}
    \end{tikzpicture}
\end{document}

环境中的很多选项axis让我眼花缭乱。Anh 这里是一个简单的 TikZ 解决方案。

在此处输入图片描述

\documentclass{article}
\usepackage{tikz,lipsum}
\begin{document}
\lipsum[1]
\begin{center}
\begin{tikzpicture}[yscale=6]
\draw[gray!50] (11,0) grid[ystep=1mm] (0,1.1);
\draw[-stealth] (0,0)--(11,0) node[below]{$f$};
\draw[-stealth] (0,0)--(0,1.1) node[above]{$|S(n\cdot\omega_0)|$};

\foreach \i/\ivalue in 
{1/.6366,2/0.3183,3/0.2122,4/0.1591,5/0.1273,6/0.1061,7/0.0909,8/0.0795,9/0.0707,10/0.0636}
\draw[red,line width=1.5pt] 
(\i,\ivalue) node[circle,fill,inner sep=2pt]{}--
(\i,0) node[below=3pt,circle,fill=pink,text=black,scale=.7,minimum size=22pt]{$\i$};

\draw[blue,line width=1.5pt] 
(0,1) node[circle,fill,inner sep=2pt]{}--(0,0);

\foreach \j in {0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1}
\path (0,\j) node[left=8pt,fill=pink,circle,scale=.7,minimum size=22pt,inner sep=1pt]{$\j$};
\end{tikzpicture}   
\end{center}
\lipsum[10] 
\end{document}

答案3

在您不完整的示例中，实心圆由箭头绘制（未显示其定义）。对于箭头，“圆的顶部刚好接触它”是预期的行为。

在以下示例中，实心圆由标记绘制（记录在手册pgfplots，第 4.7.1 节），从而解决了问题。

为了进一步改善你的情节，

  • 您可能需要minimum size=...使用yticklabel style；
  • 一些明确指定的额外刻度看起来奇怪且无用。
\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{arrows.meta}

\begin{document}
\pgfplotsset{
  x mark/.style={
    mark=*,
    mark indices=2
  }
}

\begin{tikzpicture}[scale=0.75]
  \begin{axis}[
    axis lines=center,

    xmin=-0.75,xmax=10.5,  ymax=1.1,ymin=-0.12, 
    ytick={0,0.1,...,1.1},
    xtick={0,1,...,10},
    extra y ticks={-0.12,1.1},extra x ticks={-0.75,10.5},
    extra y tick labels={},extra x tick labels={},

    xticklabel style={fill=orange!20,circle,inner sep=2pt},
    scale only axis,

    height=7cm,
