调整 pgfgantt 中 gantttitlelist 中标签的 x 位置

Question

我正在使用 pgfgantt 来制作时序图。效果很好，只是时间标签的中心点太靠右 0.5 个时间单位了。示例

\usepackage{pgfgantt}

\begin{document}
\begin{ganttchart}[
    expand chart=\textwidth,
    vgrid=true, hgrid=true,
    canvas/.style={draw=none},
    include title in canvas=false,
    y unit title=0.5cm,
    y unit chart=0.6cm,
    title/.style={draw=none, fill=none},
    title label font=\footnotesize
  ]{0}{14}
  \gantttitlelist{0,...,14}{1}\\
  \ganttbar{$\tau_1$}{0}{0}
  \ganttbar[inline]{}{3}{3} \ganttbar[inline]{}{6}{6}
  \ganttbar[inline]{}{9}{9} \ganttbar[inline]{}{12}{12}
\end{ganttchart}
\end{document}

标签 0、..、14 应位于虚线上方。

    y unit title=0.5cm,
    y unit chart=0.6cm,
    title/.style={draw=none, fill=none},
    title label font=\footnotesize,
    title left shift=-1,
  ]{0}{14}
  \gantttitlelist{0,...,14}{1}\\
  \ganttbar{$\tau_1$}{0}{0}
  \ganttbar[inline]{}{3}{3} \ganttbar[inline]{}{6}{6}
