[Tex/LaTex] Kiviat diagram with axis labeled and different sizes

tikz-pgftkz-kiviat

I am trying to use the package tkz-kiviat to draw a kiviat. The following example produces the image below:

\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}
\tkzKiviatDiagram[scale=1.25,label distance=.5cm,
        radial  = 5,
        gap     = 1,  
        lattice = 5]{McCabe,LOC,Live Variables,Halstead N,Variablenspanne}
\tkzKiviatLine[thick,color=blue,mark=none,
               fill=blue!20,opacity=.5](3,3.5,3,3.5,3)
\tkzKiviatLine[thick,color=darkgray,
               fill=green!20,opacity=.5](0.5,1,0.5,0.75,1) 
\tkzKiviatLine[ultra thick,mark=ball,
                 mark size=4pt,color =Maroon](2,3.75,1,1.5,2)    
\tkzKiviatGrad[prefix=,unity=100,suffix=\ \texteuro](1)  
\end{tikzpicture}

\end{document}

Kiviat produced with the code above

My questions are:

  1. Is it possible to have axes with different sizes? In the previous example, all the axes go from 0 to 5. I would like to have one axis from 0 to 3, other from 0 to 2, and so on.
  2. Is it possible to label the axes with enumerated values? In the previous example, instead of having 100€, 200€, etc. I would like to have Axis1: Active, Passive. Axis2: Earth, Venus, Sun, …

Is this possible with this pacakge? Do I need to use another one?

An example for my alternate approach with TikZ nodes:

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}
\usepackage{tikz}
\usepackage{xifthen}
\usepackage{wasysym}

\newcommand{\myshape}{circle}
\newcommand{\myfillcolor}{white}
\newcommand{\mydrawcolor}{black}
\newcommand{\myfontcolor}{black}
\newcommand{\mynodecontent}{black}

\newcommand{\multiscale}[2]{% mode, planet
\ifthenelse{\equal{#1}{passive}}{\renewcommand{\mydrawcolor}{green!70!blue}}{}
\ifthenelse{\equal{#1}{active}}{\renewcommand{\mydrawcolor}{red!80!yellow}}{}
% ---------
\ifthenelse{\equal{#2}{Mercury}}{\renewcommand{\myfillcolor}{black!75}\renewcommand{\mynodecontent}{\mercury}}{}
\ifthenelse{\equal{#2}{Venus}}{\renewcommand{\myfillcolor}{black!50}\renewcommand{\mynodecontent}{\venus}}{}
\ifthenelse{\equal{#2}{Earth}}{\renewcommand{\myfillcolor}{black!25}\renewcommand{\mynodecontent}{\earth}}{}
\node[color=-\mydrawcolor,draw=\mydrawcolor,fill=\myfillcolor,circle,ultra thick,minimum size=1cm] {\textbf{\mynodecontent}};
}

\begin{document}

\begin{tikzpicture}
\multiscale{passive}{Mercury}
\end{tikzpicture}
\begin{tikzpicture}
\multiscale{passive}{Venus}
\end{tikzpicture}
\begin{tikzpicture}
\multiscale{passive}{Earth}
\end{tikzpicture}

\begin{tikzpicture}
\multiscale{active}{Mercury}
\end{tikzpicture}
\begin{tikzpicture}
\multiscale{active}{Venus}
\end{tikzpicture}
\begin{tikzpicture}
\multiscale{active}{Earth}
\end{tikzpicture}


\end{document}

In this case, passive is green frame, active is red frame, and the planets become lighter gray outwards from the sun. Of course, you'd have to provide a nice key for explanation.

Edit 1: I've had a look at the documentation of tkz-kiviat and as far as I can see it is not possible. I made a little concept how it might work, but it need horribly much manual tweaking. Also, i have no idea about text labels as pgfmath can only extract numbers from array like structures. Probably you can also ask Altermundus, the author of tkz-kiviat and also a user on this site.

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}
\usepackage{tikz}

\newcommand{\kivaxisnumbers}{3}
\newcommand{\kivcategorycounts}{{2,3,4}}
\newcommand{\kivkumulativecategorycounts}{{0,2,5}}
\newcommand{\kivcategorynames}{{1,2,10,20,30,100,200,300,400}}
\newcommand{\kivlcmcatcount}{12}

\newcommand{\kivlattice}{%
\pgfmathsetmacro{\kivaxisangle}{360/\kivaxisnumbers}
    \foreach \x in {1,...,\kivaxisnumbers}
    {   \foreach \y in {1,...,\kivlcmcatcount}
        {   \pgfmathsetmacro{\kivaxisstep}{6/\kivlcmcatcount}
            \draw[help lines] (\kivaxisangle*\x:\y*\kivaxisstep) -- (\kivaxisangle*\x+\kivaxisangle:\y*\kivaxisstep);
        }
    }
    \foreach \x in {1,...,\kivaxisnumbers}
    {   \draw[->] (0,0) -- (\kivaxisangle*\x:6cm);
        \pgfmathsetmacro{\kivaxissteps}{\kivcategorycounts[\x-1]}
        \pgfmathsetmacro{\kivaxisstep}{6/\kivcategorycounts[\x-1]}
        \foreach \y in {1,...,\kivaxissteps}
        {   \pgfmathsetmacro{\kivhelper}{\kivkumulativecategorycounts[\x-1]}
            \pgfmathtruncatemacro{\kivlabelname}{\kivcategorynames[\kivhelper+\y-1]}
            \node[circle,fill=black,label=\x*\kivaxisangle+90:\kivlabelname,inner sep=1pt] at (\kivaxisangle*\x:\kivaxisstep*\y) {};
        }
    }

}

\begin{document}

\begin{tikzpicture}
\kivlattice
\end{tikzpicture}

\end{document}

Edit 2: For adding some data (in percentages of the axes):

\newcommand{\kivdatapoints}{}

\newcommand{\kivdata}[2]{% values in percentages of max, color
    \renewcommand{\kivdatapoints}{{#1}}
    \pgfmathsetmacro{\kivaxisangle}{360/\kivaxisnumbers}
    \pgfmathsetmacro{\kivcoordinate}{\kivdatapoints[0]*6}
    \fill[opacity=0.2,#2] (\kivaxisangle:\kivcoordinate) 
        \foreach \x in {1,...,\kivaxisnumbers}
        {   %\pgfmathsetmacro{\kivcoordinate}{\kivdatapoints[\x-1]*6}
            -- (\kivaxisangle*\x:\kivdatapoints[\x-1]*6) 
        }
    -- cycle;
}

\begin{document}

\begin{tikzpicture}
\kivlattice
\kivdata{0.2,0.9,0.6}{red}
\kivdata{0.7,0.1,0.8}{green}
\kivdata{0.4,0.35,0.3}{blue}
\end{tikzpicture}

Edit 3: Thanks to Brandon Kuczenski's answer in this question, I was able to add text labels to the axes:

\documentclass[parskip]{scrartcl}
\usepackage[margin=15mm]{geometry}
\usepackage{tikz}
\usepackage{arrayjobx}

\makeatletter
\usepackage{trimspaces}
\def\trimspace#1{\trim@spaces@in{#1}}
\makeatother

\newarray\kivaxisitemlabels
\readarray{kivaxisitemlabels}{%

Direction & North  & East   & South  & West  &
Taste     & Sour   & Salty  & Bitter & Sweet &
World     & Normal & Nether & End    &       }
\dataheight=5

\newcommand{\kivcurrentlabel}[2]{\checkkivaxisitemlabels(#1,#2)\trimspace\cachedata \cachedata}

\newcommand{\kivaxisnumbers}{5}
\newcommand{\kivcategorycounts}{{2,3,4,4,3}}
\newcommand{\kivkumulativecategorycounts}{{0,2,5,9,13}}

\newcommand{\kivlcmcatcount}{12}

\newcommand{\kivlattice}{%
\pgfmathsetmacro{\kivaxisangle}{360/\kivaxisnumbers}
    \foreach \x in {1,...,\kivaxisnumbers}

        {   \pgfmathsetmacro{\kivaxisstep}{6/\kivlcmcatcount}
            \draw[help lines] (\kivaxisangle*\x:\y*\kivaxisstep) -- (\kivaxisangle*\x+\kivaxisangle:\y*\kivaxisstep);
        }
    }
    \foreach \x in {1,...,\kivaxisnumbers}
    {   \draw[->] (0,0) -- (\kivaxisangle*\x:6cm);
        \pgfmathsetmacro{\kivaxissteps}{\kivcategorycounts[\x-1]}
        \pgfmathsetmacro{\kivaxisstep}{6/\kivcategorycounts[\x-1]}
        \foreach \y in {1,...,\kivaxissteps}
        {   %\pgfmathsetmacro{\kivhelper}{\kivkumulativecategorycounts[\x-1]}
            %\pgfmathtruncatemacro{\kivlabelname}{\kivcategorynames[\kivhelper+\y-1]}
            %\node[circle,fill=black,label=\x*\kivaxisangle+90:\kivlabelname,inner sep=1pt] at (\kivaxisangle*\x:\kivaxisstep*\y) {};
            \pgfmathtruncatemacro{\kivlabelnumber}{\y+1}            
            \node[circle,fill=black,label=\x*\kivaxisangle+90:\kivcurrentlabel{\x}{\kivlabelnumber},inner sep=1pt] at (\kivaxisangle*\x:\kivaxisstep*\y) {};
        }
    }
}

\newcommand{\kivdatapoints}{}

\newcommand{\kivdata}[2]{% values in percentages of max, color
    \renewcommand{\kivdatapoints}{{#1}}
    \pgfmathsetmacro{\kivaxisangle}{360/\kivaxisnumbers}
    \pgfmathsetmacro{\kivcoordinate}{\kivdatapoints[0]*6}
    \fill[opacity=0.2,#2] (\kivaxisangle:\kivcoordinate) 
        \foreach \x in {1,...,\kivaxisnumbers}
        {   %\pgfmathsetmacro{\kivcoordinate}{\kivdatapoints[\x-1]*6}
            -- (\kivaxisangle*\x:\kivdatapoints[\x-1]*6) 
        }
    -- cycle;
}

\begin{document}

\begin{tikzpicture}
\kivlattice
\kivdata{0.2,0.9,0.6,0.5,0.5}{red}
\kivdata{0.7,0.1,0.8,0.6,.2}{green}
