how to prevent combine ends of arcs of tikz-dependency

Question

How to prevent the arcs from combining with tikz-dependency, like

two arcs starting from "had" are separated from each other.

but in the picture generated by the following code, below they are not separated,

\documentclass[12pt]{article}
\usepackage{tikz-dependency}

\begin{document}

\begin{dependency}[theme = simple, edge horizontal padding=3pt]
\begin{deptext}[column sep=1em]
A \& hearing \& is \& scheduled \& on \& the \& issue \& today \& . \\
\end{deptext}
\depedge{1}{3}{ATT}
\depedge{2}{3}{ATT}
\depedge{3}{8}{SBJ}
\depedge{3}{9}{PU}
\depedge{5}{8}{VC}
\depedge{4}{8}{TMP}
\depedge{6}{8}{PC}
\depedge{7}{8}{PC}
\end{dependency}

\end{document}

I have read the tikz-dependency manual, and add the parameter 'edge horizontal padding', but the resulting picture is the same.

Is there a way to prevent the default arc combination?

Answer 1

If I understand the question correctly, you may want to use the edge start offset x and edge end offset x options. They are available since tikz-dependency v1.1 and documented on page 16 of the manual. If you apply them at the depedge level, they can shift horizontally the start/end point of each edge individually.

The example from the manual is the following:

\documentclass[12pt]{article}
\usepackage{tikz-dependency}

\begin{document}
\begin{dependency}[theme = simple]
 \begin{deptext}[column sep=1em]
  A \& hearing \& is \& scheduled \& on \& the \& issue \& today \& . \\
 \end{deptext}
 \deproot{3}{ROOT}
 \depedge{2}{1}{ATT}
 \depedge[edge start x offset=-6pt]{2}{5}{ATT}
 \depedge{3}{2}{SBJ}
 \depedge{3}{9}{PU}
 \depedge{3}{4}{VC}
 \depedge{4}{8}{TMP}
 \depedge{5}{7}{PC}
 \depedge[arc angle=50]{7}{6}{ATT}
\end{dependency}
\end{document}
