Tikz-Diagramm (Torten-, Balkendiagramm) wahlweise im Hoch- oder Querformat

Ich habe nachfolgende Torten- und Balkendiagramme. Mir gefällt die Aufteilung/Position bei einem doppelseitigen Buch noch nicht. Nun würde ich gerne wahlweise die Diagramme im Hoch- und Querformat ausgeben, je nachdem, ob ich beide Diagramme oder nur eins ausgebe. Versuche mit **landscape** sind mir bislang misslungen. \documentclass[fontsize=10pt,paper=a4,twoside]{scrbook} \usepackage[table]{xcolor} \usepackage{tikz} \usepackage{blindtext} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \definecolor{framsokn}{RGB}{24,73,42} \definecolor{sjalfstaedi}{RGB}{0,0,181} \definecolor{vinstrigraen}{RGB}{72,142,65} \definecolor{frjalslyndi}{RGB}{0,142,210} \definecolor{samfylkingin}{RGB}{198,18,24} \definecolor{borgarahreyfingin}{RGB}{242,120,31} \definecolor{lydraedishrefingin}{RGB}{198,18,24} \definecolor{klisti}{rgb}{255,247,0} \def\angle{0} \def\radius{3} \newcommand\square[1]{% \tikz\filldraw[color=#1] (0,0) rectangle (1.5ex,1.5ex);% } \newcount\ind \begin{document} \blindtext \newcommand\dataa{ 29.80/Samfylkingin/samfylkingin, 23.70/Sjálfstæðisflokkur/sjalfstaedi, 21.68/Vinstrihreyfingin--grænt framboð/vinstrigraen, 14.80/Framsóknarflokkur/framsokn, 7.22/Borgarahreyfingin/borgarahreyfingin, 2.22/Frjálslyndi flokkurinn/frjalslyndi, 0.59/Lýðræðishreyfingin/lydraedishrefingin% } \newcommand\dataaa{ 29.80/Samfylkingin/samfylkingin, 23.70/Sjálfstæðisflokkur/sjalfstaedi, 21.68/Vinstrihreyfingin--grænt framboð/vinstrigraen, 14.80/Framsóknarflokkur/framsokn, 7.22/Borgarahreyfingin/borgarahreyfingin, 2.81/Sonstige/klisti, % 0.59/Lýðræðishreyfingin/lydraedishrefingin% } \begin{tikzpicture}[scale=1.00] \begin{scope} \global\ind=-1 \foreach \percent/\name/\color in \dataaa{ \ifx\percent\empty\else % If \percent is empty, do nothing \global\advance\ind by 1 % Advance list index % Draw angle and set labels \filldraw[color=\color] (0,0) -- (\angle:\radius) arc (\angle:\angle+\percent*3.6:\radius) -- cycle; \node[anchor=base west] at (\radius+2,1.5-.5*\ind) {\square{\color} \name}; \node[pin=\angle+0.5*\percent*3.6:\percent\%] at (\angle+0.5*\percent*3.6:\radius) {}; \pgfmathparse{\angle+\percent*3.6} % Advance angle \xdef\angle{\pgfmathresult} % and store in \angle \fi }; \end{scope} \pgfmathsetmacro\barmaxheight{5} \begin{scope}[shift={(-2,-4-\barmaxheight)}] \draw[<->] (0,\barmaxheight+0.5) |- (8,0); \draw (2pt,\barmaxheight) -- (-2pt,\barmaxheight) node[left] {100\%}; \draw (2pt,.5*\barmaxheight) -- (-2pt,.5*\barmaxheight) node[left] {50\%}; \global\ind=-1 \foreach \percent/\name/\color in \dataa{ \ifx\percent\empty\else % If \percent is empty, do nothing \global\advance\ind by 1 % Advance list index % Draw angle and set labels \filldraw[color=\color] (\ind+.14,0) rectangle (\ind+1.2,\barmaxheight/100*\percent); \node[above] at (\ind+1,\barmaxheight/100*\percent) {\percent\%}; \node[rotate=45,anchor=north east] at (\ind+1,0) {\name}; \fi }; \end{scope} \end{tikzpicture} \end{document}
