这个警告是由于Matplotlib 3.6版本中，FigureCanvas需要有required_interactive_framework属性，否则会发出警告。这个属性在Matplotlib 3.8版本中将会成为必需的属性，如果没有设置，则会引发异常。

而“Glyph missing”警告则是因为所绘制的图形中包含了当前字体不支持的字符导致的。可以尝试更换字体或者忽略这个警告。

解决这些警告的方法是升级Matplotlib到最新版本，或者忽略这个警告。如果你想升级Matplotlib，可以在终端执行以下命令：

pip install --upgrade matplotlib

如果你想忽略这个警告，可以在代码开头加入以下代码：

import warnings
warnings.filterwarnings("ignore", message="Support for FigureCanvases without a required_interactive_framework attribute was deprecated in Matplotlib 3.6 and will be removed two minor releases later.")
warnings.filterwarnings("ignore", message="Glyph .* missing from current font.")

这样就可以忽略这两个警告了。当然，为了避免出现其他问题，建议还是尽量升级Matplotlib到最新版本。
