This overhaul of the docs structure puts Kibana's documentation more inline with the structure that is used in Elasticsearch. This will help us better organize the docs going forward as more docs are added. This also includes a few necessary content changes for 5.0.

This chart's Y axis is the _metrics_ axis. The following aggregations are available for this axis:
|
|
|
|
*Count*:: The {es-ref}search-aggregations-metrics-valuecount-aggregation.html[_count_] aggregation returns a raw count of
|
|
the elements in the selected index pattern.
|
|
*Average*:: This aggregation returns the {es-ref}search-aggregations-metrics-avg-aggregation.html[_average_] of a numeric
|
|
field. Select a field from the drop-down.
|
|
*Sum*:: The {es-ref}search-aggregations-metrics-sum-aggregation.html[_sum_] aggregation returns the total sum of a numeric
|
|
field. Select a field from the drop-down.
|
|
*Min*:: The {es-ref}search-aggregations-metrics-min-aggregation.html[_min_] aggregation returns the minimum value of a
|
|
numeric field. Select a field from the drop-down.
|
|
*Max*:: The {es-ref}search-aggregations-metrics-max-aggregation.html[_max_] aggregation returns the maximum value of a
|
|
numeric field. Select a field from the drop-down.
|
|
*Unique Count*:: The {es-ref}search-aggregations-metrics-cardinality-aggregation.html[_cardinality_] aggregation returns
|
|
the number of unique values in a field. Select a field from the drop-down.
|
|
*Percentiles*:: The {es-ref}search-aggregations-metrics-percentile-aggregation.html[_percentile_] aggregation divides the
|
|
values in a numeric field into percentile bands that you specify. Select a field from the drop-down, then specify one
|
|
or more ranges in the *Percentiles* fields. Click the *X* to remove a percentile field. Click *+ Add* to add a
|
|
percentile field.
|
|
*Percentile Rank*:: The {es-ref}search-aggregations-metrics-percentile-rank-aggregation.html[_percentile ranks_]
|
|
aggregation returns the percentile rankings for the values in the numeric field you specify. Select a numeric field
|
|
from the drop-down, then specify one or more percentile rank values in the *Values* fields. Click the *X* to remove a
|
|
values field. Click *+Add* to add a values field.
|
|
|
|
You can add an aggregation by clicking the *+ Add Aggregation* button.
|
|
|
|
Enter a string in the *Custom Label* field to change the display label.
|
|
|
|
The _buckets_ aggregations determine what information is being retrieved from your data set.
|
|
|
|
Before you choose a buckets aggregation, specify if you are splitting slices within a single chart or splitting into
|
|
multiple charts. A multiple chart split must run before any other aggregations. When you split a chart, you can change
|
|
if the splits are displayed in a row or a column by clicking the *Rows | Columns* selector.

|
|
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:
|
|
|
|
[source,shell]
|
|
{ "script" : "doc['grade'].value * 1.2" }
|
|
|
|
NOTE: In Elasticsearch releases 1.4.3 and later, this functionality requires you to enable
|
|
{es-ref}modules-scripting.html[dynamic Groovy scripting].
|
|
|
|
The availability of these options varies depending on the aggregation you choose.
|
|
|
|
Select the *Options* to change the following aspects of the table:
|
|
|
|
*Bar Mode*:: When you have multiple Y-axis aggregations defined for your chart, you can use this drop-down to affect
|
|
how the aggregations display on the chart:
|
|
|
|
_stacked_:: Stacks the aggregations on top of each other.
|
|
_percentage_:: Displays each aggregation as a proportion of the total.
|
|
_grouped_:: Groups the results horizontally by the lowest-priority sub-aggregation.
|
|
|
|
Checkboxes are available to enable and disable the following behaviors:
|
|
|
|
*Show Tooltip*:: Check this box to enable the display of tooltips.
|
|
*Scale Y-Axis to Data Bounds*:: The default Y axis bounds are zero and the maximum value returned in the data. Check
|
|
this box to change both upper and lower bounds to match the values returned in the data.
