我正在尝试将一个值置于概率图树的中心，但做不到。有人能帮帮我吗？这是我正在运行的代码，这是输出。我试图将值 56.444 置于中心，但没有结果。
\begin{tikzpicture}[grow=right, sloped]
\node[bag] {40}
child {
node[bag] {33.484}
child {
node[end, label=right:
{28.029}] {}
edge from parent
node[above] {}
node[below] {}
}
child {
node[end, label=right:
{39.775}] {}
edge from parent
node[above] {}
node[below] {}
}
edge from parent
node[above] {}
node[below] {}
}
child {
node[bag] {47.516}
child {
node[end, label=right:
{39.775}] {}
}
child {
node[bag, label=-45:
{56.444}] {}
child {
node[end, label=right:
{56.444}] {}
edge from parent
node[above] {}
node[below] {}
} child {
node[end, label=right:
{56.444}] {}
edge from parent
node[above] {}
node[below] {}
} }
};
\end{tikzpicture}

另外，您可以考虑使用forest，这可以使代码更简单：
\documentclass{article}
\usepackage{forest}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{forest}
for tree={grow'=east,
if n children=0{edge=-{Circle[length=2pt]}, child anchor=west}{},
l sep=1.2cm, s sep=5mm
}
[40
[47.516
[56.444
[56.444][56.444]
]
[39.775]
]
[33.484
[39.775][28.029]
]
]
\end{forest}
\end{document}
