i would like to create a ishikawa diagram (fishbone) like the following one:
I've tried to realize it with Tikz but it seems like a bit difficult.
\tikzset{
ishikawa/.style = {align=center, inner sep=0pt, text centered,
%font=\sffamily
},
matter/.style={ % Wirkung=Betrachtete Störgröße
rectangle,minimum size=6mm,very thick,draw=red!70!black!40,top color=white,bottom color=red!50!black!20,font=\itshape
},
level_1/.style={ % Haupteinflussfaktoren
ellipse,node distance=60pt,minimum size=6mm,very thick,draw=red!50!black!50,top color=white,bottom color=red!50!black!20,font= \itshape
},
level_2/.style={ % Nebeneinflussfaktoren
rectangle,minimum size=6mm,font=\itshape,font=\tiny
}
}
\begin{tikzpicture}[->,>=stealth',level/.style={sibling distance = 5cm/#1,
level distance = 1.5cm}
]
\node (Grund) [matter] at ( 12,0) {CPA};
% \path[draw,->] (0,0) -- (Grund)
\draw [->,very thick] ( 0,0) -- (Grund);
\node (tl_1_1) [level_1] at ( 0,5) {Material};
\node (bl_1_1) [level_1] at ( 0,-5) {Methode};
% child{ node [level_2] {msndfbdejfsdlfksf}}
\node (tl_1_2) [level_1, right=of tl_1_1] {Maschine};
% child{ node [level_2] {msndfbdejfsdlfksf}}
\node (bl_1_2) [level_1, right=of bl_1_1] {Mensch};
% child{ node [level_2] {msndfbdejfsdlfksf}}
\node (tl_1_3) [level_1, right=of tl_1_2] {Messtechnik};
% child{ node [level_2] {msndfbdejfsdlfksf}}
\node (bl_1_3) [level_1, right=of bl_1_2] {Mitwelt};
% child{ node [level_2] {msndfbdejfsdlfksf}}
\end{tikzpicture}
This produces my top level boxes but I don't know how to draw a path from there to my main arrow. The same problem also for the lower level arrows.
Can someone help me out?!
cheers Gerold
