我正在尝试将日期分成30 min个间隔。
问题是：上次日期正在以30 min的间隔切分。
数据：
date Estimated_values
6/4/2019 1512.172483
6/5/2019 1434.669927
6/6/2019 1394.192385
6/7/2019 1526.965799
6/8/2019 1303.677049
6/9/2019 827.6617156
我尝试过的代码：
Distribution_30min=pd.DataFrame(df['Estimated_values'].resample('30 min').sum())
Output Iam expecting: (One date example I have copied)
