Elasticsearch, usage of date_histogram's date in calculating sum aggregation

Question

{'aggs': {
    'date_range': {
         'date_histogram': {
               'field': "End", 
               'calendar_interval': '1h', 
               'format': 'yyyy-MM-dd HH:mm:ss'
           }, 'aggs': {

                            'source': 
                                "return doc['value_sum'].value * (doc['End'].value - curent_interval) / 3600000;",

                            'params': {'curent_interval': 'date_range'
                           }

Hi, I want to use the date in date_histogram when calculating sum.

Explanation via example: My date_histogram brings me the Jobs in that range hourly. Let’s take the value of the example Job here as 100watts. For example: If a Job starts at 10.00 and ends at 11.30, the histogram value at 10.00 covers between 10.00 and 11.00 and for 10.00 I need to get the sum value of 100watts and I can already get this value. Secondly, the histogram value that comes in at 11.00 covers between 11.00 and 12.00, but my Job ends at 11.30. For this, I need to make proportioning in the Script. And if I know that the value of date_histogram in this script is 11.00, I can do this calculation. The “curent_interval” value I specified in the code should be this 11.00 date_histogram value. For this, I need this value in the sum script from the date_histogram.

I want to use the prorated data in sum.
