修复图表，使之成为好看的图表

我在问题的帮助下画了这幅画这里

请注意，绘制的图表看起来不太好看，有人能修复它吗，我认为这是因为文字的大小，我无法控制它们，使它绘制得漂亮

你能看看我上次的请求吗？我已经尝试过了

\begin{figure}

\begin{tikzpicture}[every node/.style={align=center}, implies/.style={double,double equal sign distance,-implies}, rect/.style={draw, inner sep=1em},hexa/.style={regular polygon, regular polygon sides=6, shape aspect=0.5, minimum height=1cm, draw}]

\node[rect] (weak_existence) at (0, 0) {Existence\\faible\\\\\\Unicité\\trajectorielle};
\node[rect] (strong_existence) at (8, 0) {Existence\\forte\\\\\\Unicité\\en Loi};

\node[hexa] (best) at (4,0) {La meilleure\\situation\\possible};

\draw[implies] (best) -- (strong_existence);
\draw[implies] (best) -- (weak_existence);
\end{tikzpicture}
\caption{its me }

答案1

一种选择。我使用了text width和 ，minimum height这样节点将具有统一的大小。我还使用了一些辅助坐标，以便自动放置箭头。我没有为所有节点定义样式（这可能会产生不良结果，例如，在使用 的情况下），而是label使用mynode样式。我还将 改为更短的语法。由于样式将在多个图表中使用，因此我使它们可以通过 全局访问，而不是给定 的局部访问。<name>.<anchor>node cs:name=<name>, anchor=<anchor>\tikzettikzpicture

顺便说一句，您不应该手动进行交叉引用；您应该使用\label,\ref机制。
