Python Matplotlib子图2带轴标签的网格填充

非常感谢您为使subplot2grid和Axis标签能够很好地协同工作所提供的任何帮助。如图所示，一些轴标签与相邻子批次的表面重叠。
附加了一些代码，以防有帮助

    self.f0 = plt.figure(num = 0, figsize = (12, 8))#, dpi = 100)

    return

最好的 Vas

请尝试使用指南

在代码中，只需在创建

self.f0

后添加这一行：

self.f0.tight_layout()

最后的答案是： self.f0.tight_layout（）处理一些事情，并在顶部添加一些填充来说明标题
