还有一个相关的问题,因为我花了很长时间才找到答案:

如何使图例背景为空白(透明而不是白色):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

警告,您想要'none'(字符串)。None表示默认颜色。

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.
