将 xlabel 向右移动（x 标签样式不起作用？）

将 xlabel 向右移动（x 标签样式不起作用？）

我想将 xlabel“t”移动到 x 轴的右端。我尝试了 x label 样式，但不知为何不起作用。我还能尝试什么？

我可以使用单独的节点或者在函数图下方的某处使用“$t \rightarrow$”，但不幸的是我没能做到这一点。

任何提示或帮助都值得感激。提前谢谢您！

  • 请始终提供 MWE（最小工作示例），一个小但完整的文档，我们可以按原样测试/编译它。
  • 由于您没有提供，与图表相关的前言内容是未知的。
  • 您需要清理axis设置（例如，轴被定义多次）。
  • 工作xlabel style如预期，请参见下面的 MWE。
  • 看来，您遇到的麻烦的罪魁祸首是对 的定义不寻常x axis line style。 您可以使用 来实现您想要实现的目标enlarge x limits。
  • 看看以下 MWE 是否产生了您想要的结果：
