Access Elastic Map Service filesedit
[experimental] This functionality is experimental and may be changed or removed completely in a future release. Elastic will take a best effort approach to fix any issues, but experimental features are not subject to the support SLA of official GA features. Access the Elastic Map Service files via the same mechanism:
url: {
// "type" defaults to "elasticsearch" otherwise
type: emsfile
// Name of the file, exactly as in the Region map visualization
name: World Countries
}
// The result is a geojson file, get its features to use
// this data source with the "shape" marks
// https://vega.github.io/vega/docs/marks/shape/
format: {property: "features"}
To enable Maps, the graph must specify type=map in the host
configuration:
{
"config": {
"kibana": {
"type": "map",
// Initial map position
"latitude": 40.7, // default 0
"longitude": -74, // default 0
"zoom": 7, // default 2
// defaults to "default". Use false to disable base layer.
"mapStyle": false,
// default 0
"minZoom": 5,
// defaults to the maximum for the given style,
// or 25 when base is disabled
"maxZoom": 13,
// defaults to true, shows +/- buttons to zoom in/out
"zoomControl": false,
// Defaults to 'false', disables mouse wheel zoom. If set to
// 'true', map may zoom unexpectedly while scrolling dashboard
"scrollWheelZoom": false,
// When false, repaints on each move frame.
// Makes the graph slower when moving the map
"delayRepaint": true, // default true
}
},
/* the rest of Vega JSON */
}
The visualization automatically injects a "projection", which you can use to
calculate the position of all geo-aware marks.
Additionally, you can use latitude, longitude, and zoom signals.
These signals can be used in the graph, or can be updated to modify the
position of the map.
Vega visualization ignore the autosize, width, height, and padding
values, using fit model with zero padding.
