我正在学习大熊猫＆＃39;并尝试绘制id列，但我收到错误AttributeError: Unknown property color_cycle和空图。该图仅显示在交互式shell中。当我作为脚本执行时，我得到相同的错误，除了图形没有出现。
以下是日志：
>>> import pandas as pd
>>> pd.set_option('display.mpl_style', 'default')
>>> df = pd.read_csv('2015.csv', parse_dates=['log_date'])
>>> employee_198 = df[df['employee_id'] == 198]
>>> print(employee_198)

Pandas 0.17.1目前存在Matplotlib 1.5.0
的错误print pandas.__version__ print matplotlib.__version__
而不是使用
import pandas as pd
pd.set_option('display.mpl_style', 'default')
使用：
import matplotlib
matplotlib.style.use('ggplot')
