Histogram tests

Test Data

First, you need to index some test data:

DELETE /test
{}

POST /test/doc/
{"price": 10, "type": "widget"}

POST /test/doc/
{"price": 15, "type": "cog"}

POST /test/doc/
{"price": 55, "type": "widget"}

POST /test/doc/
{"price": 61, "type": "foo"}

POST /test/doc/
{"price": 70, "type": "foo"}

POST /test/doc/
{"price": 99, "type": "foo"}

POST /test/doc/
{"price": 160, "type": "foo"}

POST /test/doc/
{"price": 170, "type": "eggplant"}

POST /test/doc/
{"price": 1, "type": "eggplant"}

POST /test/doc/
{"price": 12, "type": "eggplant"}

POST /test/doc/
{"price": 112, "type": "eggplant"}

POST /test/doc/
{"price": 99, "type": "eggplant"}

Histogram org-table

POST /test/doc/_search
{
  "aggs" : {
    "prices" : {
      "histogram" : {
        "field" : "price",
        "interval" : 20,
        "min_doc_count": 0
      }
    }
  },
  "size": 0
}

key	document count
0	4
20	0
40	1
60	2
80	2
100	1
120	0
140	0
160	2

Which can then be passed into something like Gnuplot:

plot data using 1:2 with lines

POST /test/doc/_search
{
  "aggs" : {
    "my_terms_agg" : {
      "terms" : {
        "field" : "type"
      }
    }
  },
  "size": 0
}

key	document count
eggplant	5
foo	4
widget	2
cog	1
