tikzpicture - Align stacked barplot to y-axis with ymin=0 - latex

Question

I am trying to make a stacked barplot aligned to the y-axis of the tikzpicture.
\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}
As seen, I have used ymin to force it being close to the y-axis but it does not look perfect. Also, I want to be able to automate this since I have a lot of figures that needs this configuration and doing it manually takes time.

With ymin=0 and without additional enlarging of this limit:
\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}
