VoronoiTreemap – amCharts 5 Documentation

Type class

A weighted Voronoi treemap: nodes as polygon cells sized by value, each inside its parent's cell. Many items with very different values lay out poorly; group the small ones into an "Other" item.

Data item

VoronoiTreemap uses data items of type IVoronoiTreemapDataItem.

Sources

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

// Import VoronoiTreemap
import * as am5hierarchy from "@amcharts/amcharts5/hierarchy";

// Create VoronoiTreemap
am5hierarchy.VoronoiTreemap.new(root, {
  // ... config if applicable
});

<!-- Load VoronoiTreemap -->
<script src="hierarchy.js"></script>

<script>
// Create VoronoiTreemap
am5hierarchy.VoronoiTreemap.new(root, {
  // ... config if applicable
});
</script>

Inheritance

VoronoiTreemap extends Hierarchy.

VoronoiTreemap is not extended by any other symbol.

Settings

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

Read about settings concept.

active #	Type `undefined` \| `false` \| `true` Inherited from `ISpriteSettings` Applies the element's `"active"` state while `true`.
animationDuration #	Type `undefined` \| `number` Inherited from `IHierarchySettings` Duration of the drill-down animations, in milliseconds.
animationEasing #	Type `Easing` Inherited from `IHierarchySettings` Easing of the drill-down animations.
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
appearDelay #	Type `undefined` \| `number` Default `0` Inherited from `ISpriteSettings` Milliseconds to wait before the `autoAppear` animation starts. The element stays hidden until then. @since 5.21.0
appearDuration #	Type `undefined` \| `number` Inherited from `ISpriteSettings` Duration of the `autoAppear` animation, in milliseconds. Without it, the element's `stateAnimationDuration` is used. @since 5.21.0
ariaChecked #	Type `undefined` \| `false` \| `true` Inherited from `ISpriteSettings` `aria-checked` setting. This setting is ignored unless `role` is one of the following: `"checkbox"` `"option"` `"radio"` `"menuitemcheckbox"` `"menuitemradio"` `"treeitem"` On a toggle `"button"` (one with `toggleKey`) it is exposed as `aria-pressed`.
ariaControls #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-controls` setting.
ariaCurrent #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-current` setting. Click here for more info @since 5.9.8
ariaExpanded #	Type `undefined` \| `false` \| `true` Inherited from `ISpriteSettings` `aria-expanded` setting: whether the content the element shows or hides (e.g. a task's subtasks, a node's children) is shown. Click here for more info @since 5.21.0
ariaHidden #	Type `undefined` \| `false` \| `true` Inherited from `ISpriteSettings` `aria-hidden` setting.
ariaLabel #	Type `undefined` \| `string` Inherited from `ISpriteSettings` Label for the element to use for screen readers. Click here for more info
ariaLive #	Type `AriaLive` Inherited from `ISpriteSettings` `aria-live` setting.
ariaOrientation #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-orientation` setting.
ariaSelected #	Type `undefined` \| `false` \| `true` Inherited from `ISpriteSettings` `aria-selected` setting. Click here for more info @since 5.9.8
ariaValueMax #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-valuemax` setting.
ariaValueMin #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-valuemin` setting.
ariaValueNow #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-valuenow` setting.
ariaValueText #	Type `undefined` \| `string` Inherited from `ISpriteSettings` `aria-valuetext` setting.
autoAppear #	Type `undefined` \| `false` \| `true` Default `false` Inherited from `ISpriteSettings` Plays the element's reveal animation, as `appear()` does, when it is first drawn: a chart fades in, a series grows its columns or lines from the base. A series waits for its first data. It plays once: data updates do not replay it, but turning the setting off and on again does. Elements made from a template play as each one is made. An element that starts hidden (`visible: false`, or hidden in code before it is drawn) stays hidden. An `animations` entry on the same setting, such as a pulsing `opacity`, keeps playing. This is how a JSON config gets the opening animation, as a config cannot call `appear()`. chart.setAll({ autoAppear: true, appearDuration: 1000, appearDelay: 100 }); series.setAll({ autoAppear: true, appearDuration: 1000 }); chart.setAll({ autoAppear: true, appearDuration: 1000, appearDelay: 100 }); series.setAll({ autoAppear: true, appearDuration: 1000 }); Click here for more info @since 5.21.0

crisp #	Type `undefined` \| `false` \| `true` Default `false` Inherited from `ISpriteSettings` Draws the element sharply, with minimal anti-aliasing: its position is rounded to whole pixels, and `strokeWidth` is adjusted to the device pixel ratio, so lines may look thinner than expected.

pushDataItem(

data: IVoronoiTreemapDataItem,

@since 5.10.5

selectDataItem(

dataItem: DataItem

)

Returns void

Inherited from Hierarchy

Drills into a node, as a click does. Selecting the node that is already selected goes back up to its parent.

set(

key: Key,
value: Value

)

Returns Value

Inherited from Entity

Sets setting key to value and returns value. A value set this way overrides themes and templates, and stops any animation of the setting.

setFlatData(

flatData: Array

)

Returns void

Inherited from Hierarchy

Sets the data from a flat list, in which each item gives its parent's ID (in parentIdField, matching another item's idField; "parentId" and "id" when not set). The item with no parent ID (null, undefined or "") becomes the root; if there are several, only the last one is used.

setTimeout(

fn: () => void,
delay: number

)

Returns IDisposer

Inherited from Entity

Calls fn after delay milliseconds, unless the object is disposed first. Disposing the returned disposer cancels it.

show(

duration?: undefined | number

)

Returns Promise

Inherited from Sprite

Shows the element and returns a Promise that resolves when its showing animations finish.

series.show().then(function(ev) {
  console.log("Series is now fully visible");
})

series.show().then(function(ev) {
  console.log("Series is now fully visible");
})

showDataItem(

dataItem: DataItem,
duration?: undefined | number

)

Returns Promise

Inherited from Hierarchy

Shows a hidden node with all the nodes below it.

showTooltip(

point?: IPoint

)

Returns Promise | undefined

Inherited from Sprite

Shows the element's Tooltip. Does nothing if the element has no tooltipText or tooltipHTML.

startIndex()

Returns number

Inherited from Series

Returns the index of the first data item in the visible range.

toBack()

Returns void

Inherited from Sprite

Moves the element to the start of its parent's children, so it is drawn under its siblings, or, in a layout, placed first.

toFront()

Returns void

Inherited from Sprite

Moves the element to the end of its parent's children, so it is drawn over its siblings, or, in a layout, placed last.

toGlobal(

point: IPoint

)

Returns IPoint

Inherited from Sprite

Converts a point within the element to a point relative to the root.

toLocal(

point: IPoint

)

Returns IPoint

Inherited from Sprite

Converts a point relative to the root to a point within the element.

unhover()

Returns void

Inherited from Sprite

Ends a hover, as if the pointer left the element: hides its tooltip and takes it out of its hover state.

unhoverDataItem(

dataItem: DataItem

)

Returns void

Inherited from Hierarchy

Takes a data item's node out of its hover state.

@since 5.0.7

updateData(

data: Array

)

Returns void

Inherited from Component

Updates the data in place, keeping the existing data items: each object's values go into the data item at the same index. Extra objects are added as new data items, and data items beyond the new data are removed.

width()

Returns number

Inherited from Sprite

Returns the element's width in pixels.

x()

Returns number

Inherited from Sprite

Returns the element's X position in pixels, relative to its parent, without dx.

y()

Returns number

Inherited from Sprite

Returns the element's Y position in pixels, relative to its parent, without dy.
