I have a tikz graph with bend arrows and somehow tikz draws the arrow annotation (in my case just numbers) on the arrow. This happens a lot more often when the arrow is bend. It seems that tikz has no knowledge of where the annotation is with respect to the arrow. I have the self-contained code below. What I want is that annotations are above the bending and also I want to have a minimum distance (in pixel?) to the arrow that I can control. Is there something like that in Tikz?
\documentclass{article} \usepackage{tikz} \usetikzlibrary{arrows} \begin{document} \begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=2.5cm, thick,main node/.style={circle,fill=blue!10,draw,font=\sffamily\Large\bfseries}] % nodes \node[main node] (A) {A}; \node[main node] (B) [below left of=A] {B}; \node[main node] (C) [below right of=A] {C}; \node[main node] (D) [below right of=B] {D}; \node[main node] (E) [right of=C] {E}; \node[main node] (F) [above of=E] {F}; % lines \path[every node/.style={font=\sffamily\small}] (A) edge [bend right] node [right] {0.0} (B) (B) edge [loop left] node {0.0} (B) edge [bend right] node [right] {0.0} (D) edge [bend right] node[right] {0.0} (C) (C) edge [bend right] node [left] {0.0} (A) edge [bend right] node [left] {0.0} (B) edge [bend left] node [left] {0.0} (D) edge [right] node [right] {0.0} (E) (D) edge [loop below] node {0.0} (D); \end{tikzpicture} \end{document}
