{ "script" : "doc['grade'].value * 1.2" }Data Table
The rows of the data table are called buckets. You can define buckets to split the table into rows or to split the table into additional tables.
Each bucket type supports the following aggregations:
- Date Histogram
-
A {ref}search-aggregations-bucket-datehistogram-aggregation.html[date histogram] is built from a numeric field and organized by date. You can specify a time frame for the intervals in seconds, minutes, hours, days, weeks, months, or years. You can also specify a custom interval frame by selecting Custom as the interval and specifying a number and a time unit in the text field. Custom interval time units are s for seconds, m for minutes, h for hours, d for days, w for weeks, and y for years. Different units support different levels of precision, down to one second.
- Histogram
-
A standard {ref}search-aggregations-bucket-histogram-aggregation.html[histogram] is built from a numeric field. Specify an integer interval for this field. Select the Show empty buckets checkbox to include empty intervals in the histogram.
- Range
-
With a {ref}search-aggregations-bucket-range-aggregation.html[range] aggregation, you can specify ranges of values for a numeric field. Click Add Range to add a set of range endpoints. Click the red (x) symbol to remove a range.
- Date Range
-
A {ref}search-aggregations-bucket-daterange-aggregation.html[date range] aggregation reports values that are within a range of dates that you specify. You can specify the ranges for the dates using {ref}common-options.html#date-math[date math] expressions. Click Add Range to add a set of range endpoints. Click the red (/) symbol to remove a range.
- IPv4 Range
-
The {ref}search-aggregations-bucket-iprange-aggregation.html[IPv4 range] aggregation enables you to specify ranges of IPv4 addresses. Click Add Range to add a set of range endpoints. Click the red (/) symbol to remove a range.
- Terms
-
A {ref}search-aggregations-bucket-terms-aggregation.html[terms] aggregation enables you to specify the top or bottom n elements of a given field to display, ordered by count or a custom metric.
- Filters
-
You can specify a set of {ref}search-aggregations-bucket-filters-aggregation.html[filters] for the data. You can specify a filter as a query string or in JSON format, just as in the Discover search bar. Click Add Filter to add another filter. Click the
label button to open the label field, where you can type
in a name to display on the visualization. - Significant Terms
-
Displays the results of the experimental {ref}search-aggregations-bucket-significantterms-aggregation.html[significant terms] aggregation. The value of the Size parameter defines the number of entries this aggregation returns.
- Geohash
-
The {ref}search-aggregations-bucket-geohashgrid-aggregation.html[geohash] aggregation displays points based on the geohash coordinates.
Once you’ve specified a bucket type aggregation, you can define sub-buckets to refine the visualization. Click + Add sub-buckets to define a sub-bucket, then choose Split Rows or Split Table, then select an aggregation from the list of types.
You can use the up or down arrows to the right of the aggregation’s type to change the aggregation’s priority.
Enter a string in the Custom Label field to change the display label.
You can click the Advanced link to display more customization options for your metrics or bucket aggregation:
- Exclude Pattern
-
Specify a pattern in this field to exclude from the results.
- Include Pattern
-
Specify a pattern in this field to include in the results.
- JSON Input
-
A text field where you can add specific JSON-formatted properties to merge with the aggregation definition, as in the following example:

Note
|
In Elasticsearch releases 1.4.3 and later, this functionality requires you to enable {ref}modules-scripting.html[dynamic Groovy scripting]. |
The availability of these options varies depending on the aggregation you choose.
Select the Options tab to change the following aspects of the table:
- Per Page
-
This field controls the pagination of the table. The default value is ten rows per page.
Checkboxes are available to enable and disable the following behaviors:
- Show metrics for every bucket/level
-
Check this box to display the intermediate results for each bucket aggregation.
- Show partial rows
-
Check this box to display a row even when there is no result.

Enabling these behaviors may have a substantial effect on performance. |
