警告消除
以上的代码运行时会出现警告，这是因为新版本的提示
/usr/local/lib/python3.6/site-packages/pyecharts/charts/chart.py:14: PendingDeprecationWarning: pyecharts 所有图表类型将在 v1.9.0 版本开始强制使用 ChartItem 进行数据项配置 :)
super().__init__(init_opts=init_opts)
消除方案，只需在代码上添加以下代码就不会有提示了
from pyecharts.globals import WarningType
WarningType.ShowWarning = False
