Seaborn为什么要绘制两个图例,我如何删除一个并修复另一个图例?

标签: python matplotlib plot seaborn legend

运行下面显示的代码时,我得到一个包含2个图例的图形。我不知道为什么要绘制两个,而我却无法删除其中一个。我的目的是保留图例外部的图例,删除图例内部的图例,并以某种方式停止从图例外部切断图例右侧的怪异裁剪。 figure showing the two legends with random data

我之前有一个question提出了类似的要求,但是通过使用seaborns散点图而不是relplot解决了该问题。令人遗憾的是,在该问题中起作用的答案都没有在这里起作用。如果此问题是由于我试图绘制的人物类型的“非常规”方式引起的,请告诉我。正确地做比比破解解决方案要好...

您可以在代码的最后部分添加Process.Start("powershell.exe", coupleOfParameters

legend=False
