我相信seaborn需要RGBA颜色格式，所以我给了它一个RGBA元组列表，比如inmatplotlib但它不喜欢。我试着做一些类似g = sns.jointplot(plotdataandstuff)的事情，但是我不知道如何导航<seaborn.axisgrid.JointGrid at 0x135943d30>对象

sns.jointplot(x=u, y=v, color=c)

最佳答案
sns.jointplot(u, v, joint_kws={'color':None, 'c':c.tolist()})
jointplot由边上的边缘图（默认情况下为直方图）和中间的jointplot（默认情况下为散点图）组成，您可以在JointGrid documentation中阅读更多内容。
在本例中，您希望将参数传递到中间的散点图，这可以使用
joint_kws中的sns.jointplot()参数来完成。此参数接受参数名及其参数的字典，并将其传递给用于创建中间图的函数，在本例中为plt.scatter()。c参数控制颜色，并接受颜色元组列表，因此需要通过c.tolist()转换数组。最后一个警告是seaborn已经向color的plt.scatter()参数传递了一个颜色，因此我们需要将其设置为None以避免在尝试设置标记颜色两次时产生错误。
