  "aggs": {
    "create_date": {
      "date_histogram": {
        "field": "Incident_Create_Date",
        "interval": "1d",
        "format": "MM-dd-yyyy"
      },
      "aggs": {
        "avg_date_diff": {
          "avg": {
            "script": {
              "lang": "painless",
              "source": "Math.round((doc.Incident_Close_Date.value.millis-doc.Incident_Create_Date.value.millis))"
