如果要使用plot函数,需要导入matplotlib.下面是绘图代码: import matplotlib.pyplot as plt # plot显示图形, plot方法集成了直方图、条形图、饼图、折线图 stock_rise.cumsum().plot() # 需要调用show,才能显示出结果 plt.show() 结果: 关于plot,稍后会介绍API的选择。 4、自定义运算 apply(func, axis=0) ...
columns : a column, Grouper, array which has the same length as data, or list of them. Keys to group by on the pivot table column. If an array is passed, it is being used as the same manner as column values. aggfunc : function to use for aggregation, defaulting to numpy.mean. 导...
