Layout – amCharts 5 Documentation

Type class

Base class for Container layouts.

Sources

Layout can be used (imported) via one of the following packages.

// Import Layout
import * as am5 from "@amcharts/amcharts5";

// Create Layout
am5.Layout.new(root, {
  // ... config if applicable
});

<!-- Load Layout -->
<script src="index.js"></script>

<script>
// Create Layout
am5.Layout.new(root, {
  // ... config if applicable
});
</script>

Inheritance

Layout extends Entity.

Layout is extended by GridLayout, HorizontalLayout, VerticalLayout.

Settings

Set these settings on a Layout object using its set() and setAll() methods.

Read about settings concept.

animations #	Type `Array` Inherited from `IEntitySettings` Animations the element plays on its own, described as data - so they can be set from a JSON config and saved with it. Each one animates a setting of the element (or, with `target: "dataItem"`, a value of its data item - a map point's `positionOnLine`, say). They start when the setting is applied, restart when it changes, and stop when the element is disposed. A saved config keeps what was configured, never a value caught half way through an animation. sprite.set("animations", [ { key: "rotation", to: 360, duration: 4000, loops: 0 }, { key: "scale", from: 1, to: 1.3, duration: 800, loops: 0, yoyo: true, easing: "sine" } ]); @since 5.20.8
id #	Type `undefined` \| `string` Inherited from `IEntitySettings` A unique ID for looking the element up in `root.entitiesById`. Setting an ID that another element already has throws an error.
ignoreThemes #	Type `undefined` \| `false` \| `true` Default `false` Inherited from `IEntitySettings` Ignores themes: no theme rule applies to the element, not even one of the default theme. @since 5.15.6
stateAnimationDuration #	Type `undefined` \| `number` Default `0` Inherited from `IEntitySettings` How long, in milliseconds, a switch from one state to another animates. `0` switches at once.
stateAnimationEasing #	Type `$ease.Easing` Default `out(cubic)` Inherited from `IEntitySettings` Easing of the animated switch from one state to another.
themeTags #	Type `Array` Inherited from `IEntitySettings` Tags that theme rules can target. They also count for the element's children, so a rule can match a child by a tag of its parent. Click here for more info
themeTagsSelf #	Type `Array` Inherited from `IEntitySettings` Tags that theme rules can target, like `themeTags`, but only for this element, not its children. Click here for more info
themes #	Type `Array` Inherited from `IEntitySettings` Themes applied to the element and everything inside it.
userData #	Type `any` Inherited from `IEntitySettings` Any data of your own to keep with the element.

Properties

adapters #	Type `Adapters` Default `new Adapters(this)` Inherited from `Entity`
className #	Static Type `string` Default `"Layout"`
classNames #	Static Type `Array` Default `"Layout", "Entity"`

root #	Type `Root` Inherited from `Entity` The `Root` the object belongs to. @readonly @since 5.0.6
states #	Type `States` Default `new States(this)` Inherited from `Entity`
template #	Type `Template` \| `undefined` Inherited from `Entity` A `Template` applied to the object. Its settings apply where the object has none set of its own.

Methods

animate( options: `AnimationOptions` ) #	Returns `Animation` Inherited from `Settings` Animates a setting from its current value (or `from`) to `to`. The setting jumps to `from` at once. With `duration` `0`, or no value to start from, it is set to `to` at once and the returned animation is already stopped. Click here for more info
dispose() #	Returns `void` Inherited from `Settings` Disposes the object, freeing everything it holds. A disposed object can't be used again.
get( key: `Key`, fallback: `F` ) #	Returns `NonNullable` \| `F` Inherited from `Entity` Returns the value of setting `key`, run through any adapters, or `fallback` if it is not set. Click here for more info
has( key: `Key` ) #	Returns `boolean` Inherited from `Settings` Returns `true` if setting `key` is set. Click here for more info
isDisposed() #	Returns `boolean` Inherited from `Settings` Returns `true` if the object has been disposed.
