== Maps
|
|
|
|
To tell a story and answer questions about your geographical data, you can create several types of interactive maps with Visualize.
|
|
|
|
Visualize supports the following maps:
|
|
|
|
* *Coordinate* — Display latitude and longitude coordinates that are associated to the specified bucket aggregation.
|
|
|
|
* *Region* — Display colored boundary vector shapes using a gradient. Darker colors indicate larger values, and lighter colors indicate smaller values.
|
|
|
|
* *Heat* — Display graphical representations of data where the individual values are represented by colors.
|
|
|
|
NOTE: The maps in Visualize have been replaced with <<maps>>, which offers more functionality.

|
|
=== Coordinate map
|
|
|
|
Use a coordinate map when your data set includes latitude and longitude values. For example, use a coordinate map to see the varying popularity of destination airports using the sample flight data.

|
|
==== Build a coordinate map
|
|
|
|
Configure the `kibana.yml` settings and add the aggregations.
|
|
|
|
. Configure the following `kibana.yml` settings:
|
|
|
|
* Set `xpack.maps.showMapVisualizationTypes` to `true`.
|
|
|
|
* To use a tile service provider for coordinate maps other than https://www.elastic.co/elastic-maps-service[Elastic Maps Service], configure the <<tilemap-settings,tilemap settings>>.
|
|
|
|
. To display your data on the coordinate map, use the following aggregations:
|
|
|
|
* <<visualize-metric-aggregations,Metric>>
|
|
|
|
* <<visualize-bucket-aggregations,Geohash bucket aggregation>>
|
|
|
|
. Specify the geohash bucket aggregation options:
|
|
|
|
* *Precision* slider — Determines the granularity of the results displayed on the map. To show the *Precision* slider, deselect *Change precision on map zoom*. For information on the area specified by each precision level, refer to {ref}/search-aggregations-bucket-geohashgrid-aggregation.html#_cell_dimensions_at_the_equator[geohash grid].
|
|
+
|
|
NOTE: Higher precisions increase memory usage for the browser that displays {kib} and the underlying
|
|
{es} cluster.
|
|
|
|
* *Place markers off grid (use {ref}/search-aggregations-metrics-geocentroid-aggregation.html[geocentroid])* — When you selected, the markers are
|
|
placed in the center of all documents in the bucket, and a more accurate visualization is created. When deselected, the markers are placed in the center
|
|
of the geohash grid cell.
|
|
+
|
|
NOTE: When you have multiple values in the geo_point, the coordinate map is unable to accurately calculate the geo_centroid.

|
|
==== Navigate the coordinate map
|
|
|
|
To navigate the coordinate map, use the navigation options.
|
|
|
|
* To move the map center, click and hold anywhere on the map and move the cursor.
|
|
|
|
* To change the zoom level, click *Zoom In* or *Zoom out* image:images/viz-zoom.png[].
|
|
|
|
* To automatically crop the map boundaries to the
|
|
geohash buckets that have at least one result, click *Fit Data Bounds* image:images/viz-fit-bounds.png[].

|
[[region-map]]
|
|
=== Region map
|
|
|
|
Use region maps when you want to show statistical data on a geographic area, such as a county, country, province, or state. For example, use a region map if you want to see the average sales for each country with the sample eCommerce order data.

|
|
==== Build a region map
|
|
|
|
Configure the `kibana.yml` settings and add the aggregations.
|
|
|
|
. In `kibana.yml`, set `xpack.maps.showMapVisualizationTypes` to `true`.
|
|
|
|
. To display your data on the region map, use the following aggregations:
|
|
|
|
* <<visualize-metric-aggregations,Metric>>
|
|
* <<visualize-sibling-pipeline-aggregations,Sibling pipeline>>
|
|
* <<visualize-bucket-aggregations,Terms bucket aggregation>>

==== Navigate the region map
|
|
|
|
To navigate the region map, use the navigation options.
|
|
|
|
* To change the zoom level, click *Zoom In* or *Zoom out* image:images/viz-zoom.png[].
|
|

[[heat-map]]
|
|
=== Heat map
|
|
|
|
Use heat maps when your data set includes categorical data. For example, use a heat map to see the flights of origin countries compared to destination countries using the sample flight data.

[[build-heat-map]]
|
|
==== Build a heat map
|
|
|
|
To display your data on the heat map, use the supported aggregations.
|
|
|
|
Heat maps support the following aggregations:
|
|
|
|
* <<visualize-metric-aggregations,Metric>>
|
|
* <<visualize-parent-pipeline-aggregations,Parent pipeline>>
|
|
* <<visualize-sibling-pipeline-aggregations,Sibling pipeline>>

|
|
==== Change the color ranges
|
|
|
|
When only one color displays on the heat map, you might need to change the color ranges.
|
|
|
|
To specify the number of color ranges:
|
|
|
|
. Click *Options*.
|
|
|
|
. Enter the *Number of colors* to display.
|
|
|
|
To specify custom ranges:
|
|
|
|
. Click *Options*.
|
|
|
|
. Select *Use custom ranges*.
|
|
|
|
. Enter the ranges to display.
