R ggplot2使用刻面网格具有不同x轴标签的刻面网格

我在这个问题上纠缠了很长时间。基本上，我需要在二维平面网格中生成细菌分类群的堆叠条形图。这不是问题-但是，我确实需要使用2个不同的x轴标签

我已经研究了这些线程，它们很有帮助，但仍然不令人满意：

<代码>索引xx，而不是调整<代码> FACETYGRADEG/<代码>的设置，考虑根据需要的分组单独构建图。具体来说，考虑基础R的<>代码> （通过因子（s）来分割数据文件）以根据您的级别、类型和时间构建一个图的列表。 但是，需要进行调整以满足您的要求：

将对照区置于处理区上方

调整轴以避免冗余（根据图的实际数量定制，此处为4）：

• 删除第2和第4页上的y轴标题/文本/记号标记
• 删除第一个和第二个绘图上的x轴标题

使用方法避免多个图例

共享图例（调整为在绘图列表中作为第一个参数读取，并在顶部添加标题）
