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.

The X axis of this chart is the _buckets_ axis. You can define buckets for the X axis, for a split area on the
|
|
chart, or for split charts.
|
|
|
|
This chart's X axis supports the following aggregations. Click the linked name of each aggregation to visit the main
|
|
Elasticsearch documentation for that aggregation.
|
|
|
|
*Date Histogram*:: A {es-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 {es-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 {es-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 {es-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
|
|
{es-ref}common-options.html#date-math[_date math_] expressions. Click *Add Range* to add a set of range endpoints.
|
|
Click the red *(x)* symbol to remove a range.
|
|
*IPv4 Range*:: The {es-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 *(x)* symbol to
|
|
remove a range.
|
|
*Terms*:: A {es-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 {es-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 image:images/labelbutton.png[Label button icon] *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
|
|
{es-ref}search-aggregations-bucket-significantterms-aggregation.html[_significant terms_] aggregation.
|
|
|
|
Once you've specified an X axis aggregation, you can define sub-aggregations to refine the visualization. Click *+ Add
|
|
Sub Aggregation* to define a sub-aggregation, then choose *Split Area* or *Split Chart*, then select a sub-aggregation
|
|
from the list of types.
|
|
|
|
When multiple aggregations are defined on a chart's axis, 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.
