How to place a node in the middle of an arc?

Following the manual where labels are positioned on curves (\draw (0,0) .. controls (6,1) and (9,1) .. node {midway} (12,0);), I thought this must be possible with arcs as well:

    \draw (1,0) arc node[midway]{H} (0:180:1);

But that doesn't compile at all.

If I use

\draw (1,0) arc (0:180:1) node[midway]{H};

then the label isn't positioned on (or rather above) the arc but just on the bottom line centered. I don't want to manually shift or position it.


I rather want:


  • i do not get exactly what you mean with bottom line centered? The last statement will put the H on the arc, right at the middle. (So that the arc goes through the middle line in the H). – zeroth Oct 11 '12 at 19:50

  • @zeroth: That's wishful thinking, but my current version (updated recently) does not yet do that, although it appears that an upcoming version will as per the link Qrrbrbirlbel linked to.. – Peter Grill Oct 11 '12 at 20:04
  • @Qrrbrbirlbel I read the other question but it doesn't produce the right effect here, see the first screenshot – letmaik Oct 11 '12 at 20:04
