jointplot hue参数异常问题

问题遇到的现象和发生背景

根据函数定义，我在sns.jointplot函数中添加了hue参数用来将核密度图分类，但是提示警告UserWarning: The following kwargs were not used by contour: 'hue'
cset = contour_func(xx, yy, z, n_levels, **kwargs)
我的代码：

data2 = pd.read_csv(r'C:\Users\VAUBANTENG\Desktop\yaogan\prec\p12\data18.txt',sep = '\t', header = 0)
sns.jointplot(x = 'RHU_Avg', y = 'TEM_Avg', data = data2, 
              kind = 'kde', shade = False, 
             hue = 'station')

以下是数据
