== Line, Area, and Bar charts
|
|
Line, Area, and Bar charts allow you to plot your data on X/Y axis.
|
|
|
|
First you need to select your _metrics_ which define Value 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[]
|
|
|
|
include::color-picker.asciidoc[]
|
|
|
|
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
|
|
{ref}/modules-scripting.html[dynamic Groovy scripting].
|
|
|
|
The availability of these options varies depending on the aggregation you choose.
|
|
|
|
=== Metrics & Axes
|
|
|
|
Select the *Metrics & Axes* tab to change the way each individual metric is shown on the chart.

The data series are styled in the _Metrics_ section, while the axes are styled in the X and Y axis sections.

|
|
|

|
|
|
|
*Chart type*:: Choose between *Area*, *Line*, and *Bar* types.
|
|
*Mode*:: stack the different metrics, or plot them next to each other
|
|
*Value Axis*:: choose the axis you want to plot this data too (the properties of each are configured under Y-axes).
|
|
*Line mode*:: should the outline of lines or bars appear *smooth*, *straight*, or *stepped*.

|
|
|
Style all the Y-axes of the chart.
|
|

|
*Position*:: position of the Y-axis (*left* or *right* for vertical charts, and *top* or *bottom* for horizontal charts).
|

*Labels - Truncate*:::: You can enter the size in pixels to which the label is truncated
|

|
|
this box to change both upper and lower bounds to match the values returned in the data.
|
|
*Custom Extents*:::: You can define custom minimum and maximum for each axis
|
|
|
|
==== X-Axis
|

|
|

|
|
*Y-axis*:: You can choose on which (if any) of the value axes you want to display grid lines
