=== Embedding Visualizations
|
|
|
|
There are two different methods you can use to insert a visualization in your page.
|
|
|
|
To display an already saved visualization, use the `VisualizeLoader`.
|
|
To reuse an existing visualization implementation for a more custom purpose,
|
|
use the Angular `<visualization>` directive instead.
|
|
|
|
==== VisualizeLoader
|
|
|
|
The `VisualizeLoader` class is the easiest way to embed a visualization into your plugin.
|
|
It will take care of loading the data and rendering the visualization.
|
|
|
|
To get an instance of the loader, do the following:
|
|
|
|
["source","js"]
|
|
-----------
|
|
import { getVisualizeLoader } from 'ui/visualize/loader';
|
|
|
|
getVisualizeLoader().then((loader) => {
|
|
// You now have access to the loader
|
|
});
|
|
-----------
|
|
|
|
The loader exposes the following methods:
|
|
|
|
- `getVisualizationList()`: which returns promise which gets resolved with a list of saved visualizations
|
|
- `embedVisualizationWithId(container, savedId, params)`: which embeds visualization by id
|
|
- `embedVisualizationWithSavedObject(container, savedObject, params)`: which embeds visualization from saved object
|
|
|
|
Depending on which embed method you are using, you either pass in the id of the
|
|
saved object for the visualization, or a `savedObject`, that you can retrieve via
|
|
the `savedVisualizations` Angular service by its id. The `savedObject` give you access
|
|
to the filter and query logic and allows you to attach listeners to the visualizations.
|
|
For a more complex use-case you usually want to use that method.
|
|
|
|
`container` should be a DOM element (jQuery wrapped or regular DOM element) into which the visualization should be embedded
|
|
`params` is a parameter object specifying several parameters, that influence rendering.
|
|
|
|
You will find a detailed description of all the parameters in the inline docs
|
|
in the {repo}blob/{branch}/src/ui/public/visualize/loader/loader.js[loader source code].
|
|
|
|
Both methods return an `EmbeddedVisualizeHandler`, that gives you some access
|
|
to the visualization. The `embedVisualizationWithSavedObject` method will return
|
|
the handler immediately from the method call, whereas the `embedVisualizationWithId`
|
|
will return a promise, that resolves with the handler, as soon as the `id` could be
|
|
found. It will reject, if the `id` is invalid.
|
|
|
|
The returned `EmbeddedVisualizeHandler` itself has the following methods and properties:
|
|
|
|
- `destroy()`: destroys the underlying Angualr scope of the visualization
|
|
- `getElement()`: a reference to the jQuery wrapped DOM element, that renders the visualization
|
|
- `whenFirstRenderComplete()`: will return a promise, that resolves as soon as the visualization has
|
|
finished rendering for the first time
|
|
- `addRenderCompleteListener(listener)`: will register a listener to be called whenever
|
|
a rendering of this visualization finished (not just the first one)
|
|
- `removeRenderCompleteListener(listener)`: removes an event listener from the handler again
|
|
|
|
You can find the detailed `EmbeddedVisualizeHandler` documentation in its
|
|
{repo}blob/{branch}/src/ui/public/visualize/loader/embedded_visualize_handler.js[source code].
|
|
|
|
We recommend *not* to use the internal `<visualize>` Angular directive directly.
|
|
|
|
==== `<visualization>` directive
|
|
The `<visualization>` directive takes a visualization configuration and data.
|
|
It should be used, if you don't want to render a saved visualization, but specify
|
|
the config and data directly.
|
|
|
|
`<visualization vis='vis' vis-data='visData' ui-state='uiState' ></visualization>` where
|
|
|
|
`vis` is an instance of `Vis` object. The constructor takes 3 parameters:
|
|
|
|
- `indexPattern` <string>: the indexPattern you want to pass to the visualization
|
|
- `visConfig` <object>: the configuration object
|
|
- `uiState` <object>: uiState object you want to pass to Vis. If not provided Vis will create its own.
|
|
|
|
`visData` is the data object. Each visualization defines a `responseHandler`, which defines the format of this object.
|
|
|
|
`uiState` is an instance of PersistedState. Visualizations use it to keep track of their current state. If not provided
|
|
`<visualization>` will create its own (but you won't be able to check its values)
|
|
|
|
*code example: create single metric visualization*
|
|
["source","html"]
|
|
-----------
|
|
<div ng-controller="KbnTestController" class="test_vis">
|
|
<visualization vis='vis' vis-data='visData'></visualize>
|
|
</div>
|
|
-----------
|
|
["source","js"]
|
|
-----------
|
|
import { uiModules } from 'ui/modules';
|
|
|
|
uiModules.get('kibana')
|
|
.controller('KbnTestController', function ($scope) {
|
|
const visConfig = {
|
|
type: 'metric'
|
|
};
|
|
$scope.vis = new Vis('.logstash*', visConfig);
|
|
$scope.visData = [{ columns: [{ title: 'Count' }], rows: [[ 1024 ], [ 256 ]] }];
|
|
});
|
|
-----------
|
|
|
|
<visualization> will trigger `renderComplete` event on the element once it's done rendering.
