我是新来的蟒蛇策划并试图下面的代码绘制的分布seaborn,但无法看到传说,即test_label1和test_label1对剧情.

import matplotlib.pylab as plt
import seaborn as sns
import numpy as np

plt.figure("Test Plots")
lst1 = list(np.random.rand(10))
lst2 = list(np.random.rand(10))
sns.distplot(lst1, label='test_label1', color="0.25")
sns.distplot(lst2, label='test_label2', color="0.25")

plt.show()

我无法在我的macbook上的R版本3.3.0上安装xts软件包.我收到以下错误:

install.packages("xts",repos ="http://R-Forge.R-project.org")

警告:无法访问存储库http://R-Forge.R-project.org/bin/macosx/mavericks/contrib/3.3的索引:无法打开URL" http://R-Forge.R-project.org/ bin/macosx/mavericks/contrib/3.3/PACKAGES '

警告消息:包'xts'不可用(对于R版本3.3.0)

我也尝试通过"Package Installer"进行安装,它似乎安装时没有错误/警告.但是,当我尝试以下时:

XTS(RNORM(231),as.Date(13514:13744,原点= "1970-01-01"))

错误:找不到函数"xts"

任何帮助深表感谢.

我正在尝试按如下方式进行嵌套分组：

>>> df1 = pd.DataFrame({'Date': {0: '2016-10-11', 1: '2016-10-11', 2: '2016-10-11', 3: '2016-10-11', 4: '2016-10-11',5: '2016-10-12'}, 'Stock': {0: 'ABC', 1: 'ABC', 2: 'ABC', 3: 'ABC', 4: 'ABC', 5: 'XYZ'}, 'Quantity': {0: 60,1: 50, 2: 40, 3: 30, 4: 20, 5: 10}, 'UiD':{0:1,1:1,2:1,3:2,4:2,5:3}, 'StartTime': {0: '08:00:00.241', 1: '08:00:00.243', 2: '12:34:23.563', 3: '08:14.05.908', 4: '18:54:50.100', 5: '10:08:36.657'}, 'Sign':{0:1,1:1,2:0,3:-1,4:0,5:-1}, 'leg1':{0:2,1:2,2:4,3:5,4:7,5:8}})
