Question

请帮助我为什么当我使用hue属性时，直方图未显示在图中？

代码：

        from matplotlib import pyplot as plt 
        import pandas as pd 
        import seaborn as sb 
        my_array =[
                         ['Galaxy S8', 'Android', 64, 4, 149.0 ,'Samsung' ,5.8],
                         ['Lumia950' ,'windows' ,32, 3 ,150.0 ,'Microsoft', 5.2],
                         ['Xpreia L1', 'Android', 16, 2, 180.0,'Sony' ,5.5],
                         ['iphone 7', 'ios', 128 ,2, 138.0 ,'Apple' ,4.7],
                         ['U Ultra', 'Android', 64, 4 ,170.0, 'HTC', 5.7],
                         ['Galaxy S5' ,'Android', 16 ,2, 145.0 ,'Samsung' ,5.1],
                         ['iphone 5s', 'ios', 32, 1, 112.0 ,'Apple' ,4.0],
                         ['Moto G5' ,'Android' ,16, 3 ,144.5 ,'Motorola', 5.0],
                         ['Pixel', 'Android' ,128 ,4 ,143.0 ,'Google' ,5.0]   
                        ]
        smart_phones = pd.DataFrame(my_array , index = [0,1,2,3,4,5,6,7,8] , 
        columns=['Name', 'OS', 'Capacity' ,'Ram', 'Weight', 'Company', 'inch'])

        sb.pairplot(smart_phones , hue="Name" , palette="hls" ,plot_kws={'s':80})

        plt.show();

错误：

        C:\ProgramData\Anaconda3\lib\site-packages\numpy\core\_methods.py:140: 
        RuntimeWarning: Degrees of freedom <= 0 for slice
          keepdims=keepdims)
        C:\ProgramData\Anaconda3\lib\site-packages\numpy\core\_methods.py:132: 
        RuntimeWarning: invalid value encountered in double_scalars
          ret = ret.dtype.type(ret / rcount)

谢谢您的回复

如果您希望查看带有该数据的成对图，则需要删除hue参数或将其更改为类似hue='OS'的

将其作为每个电话的名称是没有道理的，因为每个值都与上一个不同。

以下是使用sb.pairplot(smart_phones , hue='OS',palette="hls" ,plot_kws={'s':80})

的示例
