使用控件而不影响图像大小

我有以下树forest：

\documentclass{article}                          


\usepackage{forest}

\usetikzlibrary{arrows}
\tikzset{
    %Define standard arrow tip
    >=stealth'}

当我编译它时，标题离图片很远。原因是控制点的规格为 6cm。因此，tikz在确定图像大小时似乎要考虑控制点。我能做些什么呢？我缩短了 6cm，但这给出了其他曲线。

您可以将\draw命令放置在pgfinterruptboundingbox环境中。

在此处输入图片描述
