=== Vertical Bar Charts
|
|
|
|
This chart's Y axis is the _metrics_ axis. The following aggregations are available for this axis:
|
|
|
|
include::y-axis-aggs.asciidoc[]
|
|
|
|
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.
|
|
|
|
include::x-axis-aggs.asciidoc[]
|
|
|
|
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.
|
|
*Exclude Pattern Flags*:: A standard set of Java flags for the exclusion pattern.
|
|
*Include Pattern*:: Specify a pattern in this field to include in the results.
|
|
*Include Pattern Flags*:: A standard set of Java flags for the inclusion pattern.
|
|
*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
|
|
{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.
|
|
*Show Legend*:: Check this box to enable the display of a legend next to the chart.
|
|
*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.
