Is there any workaround to use [pos=] or [midway] option in a node following a "plot" to annotate the path? The following minimal example will have the node text missing:


    \draw[very thin,color=gray] (-0.1,-0.1) grid (2.9,4.1);
    \draw[->] (-0.2,0) -- (3.2,0) node[right] {$x$};
    \draw[->] (0,-0.2) -- (0,4.2) node[above] {$f(x)$};

    \draw[domain=0:3] plot (\x,{\x^2}) node[midway, sloped] {midway?};

I forgot decoration

last version



   postaction={ decorate,transform shape,
   decoration={ markings, mark=at position .5 with \node #1;}}}]
\draw[very thin,color=gray] (-0.1,-1.1) grid (3.9,3.9); 

\draw[red,label={[above]{$f(x)=x^2$}}] plot(\x,{\x^2}) ;

thanks for your quick answer. Using this, we however lost the nice /tikz/sloped option that puts the label along the path. –  YIchun Jun 24 '11 at 17:32
@YIchun I forgot the decoration see my new answer –  Alain Matthes Jun 24 '11 at 18:24
@YIchun Third version :( –  Alain Matthes Jun 24 '11 at 18:32
@YIchun But I don't like the `sloped' labels ! –  Alain Matthes Jun 24 '11 at 18:36
@Chernoff You need only to remove transform shape –  Alain Matthes Sep 20 '12 at 4:51
