使用 tikz 标记带有文本的箭头

Question

我的代码如下：

\documentclass{book}
\usepackage{tikz}%
\usetikzlibrary{shapes.arrows}%
\begin{document}

\def\splarrow#1{%
\begin{tikzpicture}%
[every node/.style={single arrow,draw=none}]\node[fill=cyan]{#1};%
\end{tikzpicture}}%

\splarrow{Arrow 1}

\end{document}

我得到的输出为：

但实际上我需要的是：

请建议如何修复它...

Answer 1

您可以使用smartdiagramClaudio Fiandrino 的非代码两侧箭头指向同一方向的单箭头，只需进行一些小修改。我在代码中对修改的地方添加了注释。

\begin{document}

\begin{tikzpicture}

\diagram{One/blue!50,Two/red!50,Three/green!50}

\end{document}

或者如果您想要相同颜色的色调，您可以尝试以下方法：
