我正在使用该tkz-kiviat包绘制蜘蛛图，并且对此非常满意。我知道如何添加轴标签，但如何标记每个节点的单个值？文档中似乎没有解决这个问题的方法...
我正在尝试为球添加特定的值。
\documentclass[]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[upright]{fourier}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage{tkz-kiviat,numprint,fullpage}
\usetikzlibrary{arrows}
\thispagestyle{empty}
\begin{document}
\begin{tikzpicture}[label distance=.15cm]
\tkzKiviatDiagram[radial=5, radial style/.style ={-}, lattice style/.style ={blue!30}]%

\tkzKiviatLine[thick,color=red,mark=ball, ball color=red,mark size=4pt,fill=red!20](5,9,6,8,4)
\tkzKiviatLine[thick,color=blue,mark=ball,mark size=4pt,fill=blue!20,opacity=.5](9,6,8,4,5)
\end{tikzpicture}

这个答案没有使用tkz-kiviat，但它仍然做了它应该做的事情（不需要额外的包）。您必须手动指示轴的数量以及节点的位置，当然还有您的标签。
\documentclass[]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[upright]{fourier}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage{tkz-kiviat,numprint,fullpage}
\usetikzlibrary{arrows}
\thispagestyle{empty}
\begin{document}
\begin{tikzpicture}[label distance=.15cm]
\tkzKiviatDiagram[radial=5, radial style/.style ={-}, lattice style/.style ={blue!30}]%
{Poissons,Légumes,Viande,Lait,Pain}
\tkzKiviatLine[thick,color=red,mark=ball, ball color=red,mark size=4pt,fill=red!20](5,9,6,8,4)
\tkzKiviatLine[thick,color=blue,mark=ball,mark size=4pt,fill=blue!20,opacity=.5](9,6,8,4,5)
% the distance between two grid lines is 0.5
%we have 5 axis so the angle between two axis is 360/5 = 72
\def\noaxes{5}
\def\ang{(360/\noaxes)};
\draw ((2.5,0)node[anchor=south] {a1};
\draw ((4.5,0)node[anchor=south] {a2};
% e.g. 9 is the position of the node
\draw ((9*cos{\ang}/2,9*sin{\ang}/2)node[anchor=south] {b1};
\draw ((6*cos{\ang}/2,6*sin{\ang}/2)node[anchor=south] {b2};
\draw ((6*cos{(2*\ang)}/2,6*sin{(2*\ang)}/2)node[anchor=south] {c1};
\draw ((8*cos{(2*\ang)}/2,8*sin{(2*\ang)}/2)node[anchor=south] {c2};
\draw ((8*cos{(3*\ang)}/2,8*sin{(3*\ang)}/2)node[anchor=south] {d1};
\draw ((4*cos{(3*\ang)}/2,4*sin{(3*\ang)}/2)node[anchor=south] {d2};
\draw ((4*cos{(4*\ang)}/2,4*sin{(4*\ang)}/2)node[anchor=south] {e1};
\draw ((5*cos{(4*\ang)}/2,5*sin{(4*\ang)}/2)node[anchor=south] {e2};
\end{tikzpicture}
\end{document}
或者您也可以添加以下内容\newcommand
\newcommand{\annotMark}[5]{
%can be called with \annotMark{<noaxis>}{<angle>}{<"ccordinate">}{<gap>}{<lable>}; stadart value for gap (i.e. gap is not specified =0.5}
\pgfmathsetmacro{\xcor}{#3*cos{(#1*#2)}/(1/#4)};
\pgfmathsetmacro{\ycor}{#3*sin{(#1*#2)}/(1/#4)};
\draw (\xcor,\ycor)node[anchor=south]{#5};
}
并通过调用此命令进行注释（此示例针对 b1 注释）
\annotMark{1}{\ang}{9}{0.5}{b1};
此命令还能够处理不同的网格大小（gap）
为了清楚起见，径向线的数量决定了角度的大小\ang（例如，如果你有两条径向线\ang= 180 度）
正如你在 MWE 中看到的，我为此使用了以下代码
\def\noaxes{<number of radials>}
\def\ang{(360/\noaxes)};
因此，此代码适用于任意数量的径向线。您只需\annotMark{1}{\ang}{<position>}{<gap>}{<label>}对每个标记使用。
答案2
非常感谢 Zwähnia 提供的代码
我尝试使用以下解决方案将其调整为 4 射线图（如果有人想做同样的事情）。
\begin{tikzpicture}
\tkzKiviatDiagram[scale=0.4,label distance=1cm,
radial = 4,
gap = 1,
label space = 2.5,
lattice = 5]
{Raw Materials,Labour,Capital, Energy}
\tkzKiviatLine[thick,color=blue,mark=ball,
ball color=blue,mark size=3pt,fill=blue!100](3,4,2,4)
%\tkzKiviatGrad[prefix=,unity=1](0)
\node[anchor=south west,xshift=-60pt,yshift=40pt] at (current bounding box.south east)
{
\begin{tabular}{@{}lp{10cm}@{}}
\textcolor{blue!100}{\rule{2ex}{2ex}} & Inputs requirements \\
\end{tabular}
};
\draw ((0.5,4)node[anchor=south] {4};
\draw ((3.5,0)node[anchor=south] {3};
\draw ((0.5,-5.5)node[anchor=south] {4};
\draw ((-2.5,0)node[anchor=south] {2};
\end{tikzpicture}
