Nested Bucket Aggregation

[Camilo_Salomon (Camilo Salomón)]

I'm trying to do an aggregation over nested buckets, something like this

But I don't know how to do get the expected Result. Any advice will be appreciated.

Here is my current query:

POST kibana_sample_data_ecommerce/_search
{
  "size": 0,
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "order_date": {
              "gt": "now-1M",
              "lte": "now"
            }
          }
        }
      ]
    }
  },
  "aggs": {
    "day_histo": {
      "date_histogram": {
        "field": "order_date",
        "calendar_interval": "day"
      },
      "aggs": {
        "qmin_histo": {
          "date_histogram": {
            "field": "order_date",
            "calendar_interval": "hour"
          },
          "aggs": {
            "qminute_sum": {
              "sum": {
                "field": "taxful_total_price"
              }
            },
            "cumulative_qminute_sum": {
              "cumulative_sum": {
                "buckets_path": "qminute_sum"
              }
            }
          }
        }
      }
    }
  }
}
