对于下图，我需要显示两个 x 轴标签，如图所示。问题是我需要较低的温度标签出现在图中“HERE”的位置。我可以使用 将above文本放置在节点位置上方，但当我使用 时轴标签不会出现below。如果我从节点位置省略above或below，则文本的上半部分将显示在轴线的顶部。
我跟着答案与这篇文章类似，但有一个重要的区别（据我所知）。我已将默认轴标签设置为位于图表上方，次要标签位于图表下方。
这是一系列图表中的一张。我正在逐项“构建”图表，以便让学生了解情况。我想暂时添加额外的 x 轴标签以方便定位。下一张图表将对第二个变量（种子大小）执行相同的操作。其余图表的标签仅在图表上方。

我只是为了好玩才这么做的xslant。
