我有一份包含多变量微积分不同主题的文档。我想在文档开头添加一个条形图，根据文档中的问题数量显示每种问题的数量。换句话说，我希望条形图显示在下方
根据文档的内容和节数自动生成。然而，我在尝试实现自动化时遇到了很多问题。
- 我无法将条形图放在文档开头，因为尚未定义用于计数子部分的计数器。可以
totcount在这里完成这项工作吗？ symbolic y coords我无法使用循环创建内容foreach。- Nameref 内部不起作用
symbolic y coords
任何帮助解决这三个问题的帮助都将不胜感激。

答案1
有些解决方法简单，有些则不那么简单。主要方法是使用refcount以提供 的可扩展版本\nameref。
另一个技巧是仅在计数器注册后才排版表格和图形，否则第一次运行 LaTeX 时会出现错误。

答案2
- 这是一个未完成尝试解决问题。
- 我会使用计数器，然后将计数器值存储在 a 中
\command，然后在里面使用它pgfplots。 - 但我并没有解决这个问题。文档开头的计数器值始终为零。也许可以像在目录生成中存储的那样存储它 (@experts)。
