I tried setting edge from parent/.style={draw, bend left=60}, but the line remains straight. What am I doing wrong?


        every node/.style={
        edge from parent/.style={
                bend left=25,
\node {}
        child {node {}}
        child {node {}};

Could you provide a mwe? – Claudio Fiandrino Aug 23 '12 at 9:54
@Claudio Added it now. – Vegard Aug 23 '12 at 10:05
Sorry to insist but that's not a MWE. It should start with \documentclass{} and up to \end{document} with necessary libraries etc. The common problem for us is to guess if any library is needed or not. – percusse Aug 23 '12 at 10:16
Sorry, I didn't realise that I should add the rest too (I thought that was part of being minimal). Here it is. – Vegard Aug 23 '12 at 10:20

Found the solution. Instead of

    edge from parent/.style={
            bend left=25,

I put

    edge from parent path={
            (\tikzparentnode\tikzparentanchor) edge [bend left=25]  (\tikzchildnode\tikzchildanchor)

and it worked!

The explanation is that bend left only makes sense in a to or edge path construction. The default edge from parent path is drawn with just a line-to: --. – Loop Space Aug 23 '12 at 11:07
(Well done for figuring it out yourself, by the way) – Loop Space Aug 23 '12 at 11:08
