添加子标题时出现问题

如何为条形图添加子标题？

我想要为这三个条形图和标题图 1 添加子标题 (a)、(b)、(c)：....

编辑：

  • 我对你问题的理解与@js bibra 不同...你喜欢有参考吗副标题例如下面每个图表？

无关：

  • 不要使用resizebox，它会使图表中使用的文本与文本中的字体不一致。最好定义图表的宽度（参见下面的 MWE）。
  • \pgfplotsset您可以为此图中的所有图表定义通用的“样式” （参见下面的 MWE）。

摘自手册第 121pgfplots页

/pgfplots/title={text}

可以用作标题——放置选项在同一页——http://mirror.iopb.res.in/tex-archive/graphics/pgf/contrib/pgfplots/doc/pgfplots.pdf

在此处输入图片描述

因此添加title=caption将为您提供以下标题
