Python 3.x 在Seaborn中使用{scatter，line}kus参数

我正试图使用\u kws参数自定义一个regplot，但出现了一个异常。事实上，我不知道如何使用这个参数，如何向它传递值，甚至不知道我可以通过这个参数影响什么类型的属性。我找不到相关的文档和示例

下面是返回异常的代码示例。我也尝试了其他方法，但都返回了错误消息

查看以下内容：

可以看出，它们是

regplot

的关键字参数，并且是字典。此外，可以通过查看

plt.plot

和

plt.scatter

的文档找到可接受的参数，具体取决于您使用的参数

因此，对regplot的调用如下所示：

sns.regplot(data= toy_data,
            y='Tuition',
            x="REGION",
            x_estimator=np.mean,
            scatter_kws={'c': 'r'},
            line_kws={'color': 'b'})

可能重复的

sns.regplot(data= toy_data,
            y='Tuition',
            x="REGION",
            x_estimator=np.mean,
            scatter_kws={'c': 'r'},
            line_kws={'color': 'b'})
