tikzpicture-将堆叠的条形图与ymin = 0对齐到y轴

Question

我正在尝试使堆叠的条形图与tikzpicture的y轴对齐。

\begin{tikzpicture}
\begin{axis}[
    ybar stacked,
    bar width=15pt,
    ymin=29,
    nodes near coords,
    enlargelimits=0.15,
    legend style={at={(0.5,-0.15)},
      anchor=north,legend columns=-1},
    ylabel={Seconds (s)},
    symbolic x coords={t1, t2, t3, t4},
    xtick=data,
    x tick label style={rotate=45,anchor=east},
    ]
    \addplot+[ybar] plot coordinates {(t1, 143) (t2, 203) (t3, 174) (t4, 188)};
    \addplot+[ybar] plot coordinates {(t1, 34) (t2, 36) (t3, 39) (t4, 35)};
  \legend{\strut S1,\strut  S2}
  \end{axis}
\end{tikzpicture}

如所见，我已经使用ymin使其逼近y轴，但看起来并不完美。另外，我希望能够自动执行此操作，因为我有很多需要此配置的数据，而手动执行此操作需要花费时间。

使用ymin=0，并且没有进一步扩大此限制：

\documentclass{article}

\usepackage{pgfplots}

\begin{document}


\begin{tikzpicture}
\begin{axis}[
    ybar stacked,
    bar width=15pt,
    ymin=0,
    nodes near coords,
%    enlargelimits=0.15,
    legend style={at={(0.5,-0.15)},
      anchor=north,legend columns=-1},
    ylabel={Seconds (s)},
    symbolic x coords={t1, t2, t3, t4},
    xtick=data,
    x tick label style={rotate=45,anchor=east},
    ]
    \addplot+[ybar] plot coordinates {(t1, 143) (t2, 203) (t3, 174) (t4, 188)};
    \addplot+[ybar] plot coordinates {(t1, 34) (t2, 36) (t3, 39) (t4, 35)};
  \legend{\strut S1,\strut  S2}
  \end{axis}
\end{tikzpicture}

\end{document}
