带有数字标签的单个子图

Question

我正在使用subfigure并希望figure使用一个(a),(b)编号标签来代替标签，例如(1),(2)。子图环境中的子图编号（子标题包）演示如何使用 获取罗马数字\renewcommand\thesubfigure{\roman{subfigure}}。我可以调整它来提供数字吗？

另外，我只想让这个影响一个图。所以把它\renewcommand放在文档开头的序言部分并不是我想要的。我想也许我需要把它放在我的图之前，然后我必须立即切换回\renewcommand\thesubfigure{\alph{subfigure}}给出字母标签的图。这是最好的方法吗？

\renewcommand\thesubfigure{\arabic{subfigure}}在这里：在相关的后面插入\begin{figure}。这样，修改将仅限于此图形环境：
