如何使用 tkzKiviatDiagram 更改梯度值?

如何使用 tkzKiviatDiagram 更改梯度值?

是否可以将 tkzKiviatGrad 比例改为从 -2 开始而不是从 0 开始?因此,以下示例中的销售额将是 -2 -1 0 1 2。

另外,我可以以某种方式显示图表中心的起点吗?

\documentclass{article}
\usepackage[table,dvipsnames]{xcolor}
\usepackage{tkz-kiviat}
\usetikzlibrary{arrows,positioning,fit}
\begin{document}

\begin{figure}[h!]
\centering
\begin{tikzpicture}
\tkzKiviatDiagram[scale=0.8,label distance=1cm,
        gap     = 1.5,  
        lattice = 4]{Barfoo1,Barfoo2,Barfoo3,Barfoo4,Barfoo5,Barfoo6}
\tkzKiviatLine[thick,color=blue](1,2,3,2,4,0)
\tkzKiviatLine[thick,color=yellow](1,2,4,1,4,2)
\tkzKiviatLine[thick,color=green](1,4,4,2,4,4)
\tkzKiviatLine[thick,color=Aquamarine](1,2,3,1,2,2)
\tkzKiviatLine[thick,color=Magenta](1,3,4,1,4,3)
\tkzKiviatGrad[unity=1](0)
\node[anchor=south west,xshift=-60pt,yshift=40pt] at (current bounding box.south east) 
{
\begin{tabular}{@{}lp{4cm}@{}}
\cellcolor{blue} & Foobar1 \\
\cellcolor{yellow} & Foobar2 \\
\cellcolor{green} & Foobar3\\
\cellcolor{Aquamarine} & Foobar4 \\
\cellcolor{Magenta} & Foobar5 \\
\end{tabular}
};
\end{tikzpicture}
\end{figure}

\end{document}

要解决问题,请查看tkz-kiviat.sty以及 的定义\tkzKiviatGrad

结果:

1. 如何仅改变梯度值?(仅解决问题 1)

您可以使用\patchcmdwith\usepackage{etoolbox}重新定义文件内的命令.sty。您必须用\makeatletterand包围重新定义\makeatother,以便能够访问或修改名称中包含 @ 符号的命令。(参考:@Frank Mittelbach 的方法:修改.sty 文件?

要将您的比例从 转移0 1 2 3 4到 ,-2 -1 0 1 2您必须使用下面的重新定义减去2(从定义\pgfmathparse内部的计算值\def\tkz@KiviatGrad):

\usepackage{etoolbox}
\makeatletter
\patchcmd{\tkz@KiviatGrad}{\pgfmathresult}{\pgfmathresult-2}
         {\typeout{*** SUCCESS ***}}
         {\ERRORpatchfailed}
\makeatother 

2. 中心显示起点(解决问题 1 和 2)

对于第二个问题,我只找到了重新定义整个定义的解决方案。因为for-loopwith 变量\nv必须以 i 开头,0而不是,1所以将以下内容添加到您的序言中。要解决问题 1,请以相同的方式将其替换\pgfmathtruncatemacro{\result}{\pgfmathresult}\pgfmathtruncatemacro{\result}{\pgfmathresult-2}. : (参考:@Werner 的方法:使用 \makeatletter 进行本地重新定义... \makeatother

\makeatletter
\def\tkzKiviatGrad{\pgfutil@ifnextchar[{\tkz@KiviatGrad}{\tkz@KiviatGrad[]}} 
\def\tkz@KiviatGrad[#1](#2){% 
\begingroup
\pgfkeys{/kiviatgrad/.cd,
graduation distance= 0 pt,
prefix ={},
suffix={},
unity=1
 }
 \pgfqkeys{/kiviatgrad}{#1}% 
\let\tikz@label@distance@tmp\tikz@label@distance
\global\let\tikz@label@distance\tkz@kiv@grad
 \foreach \nv in {0,...,\tkz@kiv@lattice}{ %original: \foreach \nv in {1,...,\tkz@kiv@lattice}{
 \pgfmathparse{\tkz@kiv@unity*\nv} 
 \pgfmathtruncatemacro{\result}{\pgfmathresult-2} %original: \pgfmathtruncatemacro{\result}{\pgfmathresult}
 \protected@edef\tkz@kiv@gd{\tkz@kiv@prefix$\result$\tkz@kiv@suffix}
    \path[/kiviatgrad/.cd,#1] (0:0)--(360/\tkz@kiv@radial*#2:\nv*\tkz@kiv@gap) 
       node[label=(360/\tkz@kiv@radial*#2)-90:\tkz@kiv@gd] {}; 
      }
 \let\tikz@label@distance\tikz@label@distance@tmp
