ArcDiagram

Type class

Arc diagram: nodes as circles in a row or column, sized by their values and linked by arcs.

More info: Flow chartsrmation

Data item

ArcDiagram uses data items of type IArcDiagramDataItem.

Sources

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

// Import ArcDiagram
import * as am5flow from "@amcharts/amcharts5/flow";


// Create ArcDiagram
am5flow.ArcDiagram.new(root, {
  // ... config if applicable
});

Inheritance

ArcDiagram extends Flow.

ArcDiagram is not extended by any other symbol.

Settings

Set these settings on a ArcDiagram object using its set() and setAll() methods. Read about settings concept.

animationDuration

Type undefined | number

Duration of the animation that moves nodes to new positions when values change, for example after a node is toggled, in milliseconds.

animationEasing

Type Easing

Easing of the node animation set by animationDuration.

minRadius

Type undefined | numberDefault 5

Smallest radius of a node circle, in pixels. The largest follows from the space available.

orientation

Type "horizontal" | "vertical"Default "horizontal"

Puts the nodes in a row along the bottom with arcs above them ("horizontal"), or in a column on the left with arcs to the right ("vertical"). Set it when creating the series; it can't be changed later.

radiusKey

Type "sum" | "sumIncoming" | "sumOutgoing" | "none"Default "sum"

Node value that sizes the circles: "sum" (all links), "sumIncoming", "sumOutgoing", or "none" for circles all the same size.

125 inherited items
active

Type undefined | false | trueInherited from ISpriteSettings

Applies the element's "active" state while true.

animations

Type ArrayInherited from IEntitySettingsSince 5.20.8

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" }
]);
appearDelay

Type undefined | numberDefault 0Inherited from ISpriteSettingsSince 5.21.0

Milliseconds to wait before the autoAppear animation starts. The element stays hidden until then.

appearDuration

Type undefined | numberInherited from ISpriteSettingsSince 5.21.0

Duration of the autoAppear animation, in milliseconds. Without it, the element's stateAnimationDuration is used.

ariaChecked

Type undefined | false | trueInherited 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 | stringInherited from ISpriteSettings

aria-controls setting.

ariaCurrent

Type undefined | stringInherited from ISpriteSettingsSince 5.9.8

aria-current setting.

More info: https://w3c.github.io/aria/#aria-current

ariaExpanded

Type undefined | false | trueInherited from ISpriteSettingsSince 5.21.0

aria-expanded setting: whether the content the element shows or hides (e.g. a task's subtasks, a node's children) is shown.

More info: https://w3c.github.io/aria/#aria-expanded

ariaHidden

Type undefined | false | trueInherited from ISpriteSettings

aria-hidden setting.

ariaLabel

Type undefined | stringInherited from ISpriteSettings

Label for the element to use for screen readers.

More info: Accessibility: screen reader

ariaLive

Type AriaLiveInherited from ISpriteSettings

aria-live setting.

ariaOrientation

Type undefined | stringInherited from ISpriteSettings

ariaSelected

Type undefined | false | trueInherited from ISpriteSettingsSince 5.9.8

aria-selected setting.

More info: https://w3c.github.io/aria/#aria-selected

ariaValueMax

Type undefined | stringInherited from ISpriteSettings

aria-valuemax setting.

ariaValueMin

Type undefined | stringInherited from ISpriteSettings

aria-valuemin setting.

ariaValueNow

Type undefined | stringInherited from ISpriteSettings

aria-valuenow setting.

ariaValueText

Type undefined | stringInherited from ISpriteSettings

aria-valuetext setting.

autoAppear

Type undefined | false | trueDefault falseInherited from ISpriteSettingsSince 5.21.0

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 });
