问题 1：我试图生成一个条形图，每个图表有 3 个条形。但从下面的输出中可以看出，我的 x 轴标签重复了两次。X 轴标签 = {3-6, 6-12, 12-24}
问题 2：当我在 overleaf 上编译代码时，我得到了位于中心的完整图片，而当我将代码粘贴到另一个文档中时，它占用了大量空间（因为整个 pdf 页面都被复制到另一个文档中）。有没有办法，当我编译项目时，我只会得到一个仅限于该图像的 pdf 下载？

有人能帮我解决这个问题吗？

答案1
- 您的问题不完全清楚，例如，如何将该图像插入到您的真实（最终）文档中？
- 对于页面上的图形定位，请尝试使用放置位置选项，即
\begin{figure}改写\begin{figure}[ht]或\begin{figure}[!ht]。 - 按照下面的 MWE 中的方式清理您的
groupplot设置，并稍微重新组织您的图形代码后，在本地 MiKTeX 安装以及 Overleaf 上的编译都会产生相同的结果。 - 此次清理工作是根据我之前对您问题（无需添加
xtick选项）：

关于问题 1：添加带有符号标签的 xtick 命令（见下文）对我来说很有帮助。
关于问题 2：如果我理解正确的话，将文章类从文档替换为独立类对我来说就完成了（我必须删除图形环境+标题）
