ILineSettings

Type interface

Sources

ILineSettings is an interface: it describes a shape of data and is not imported on its own.

Inheritance

ILineSettings extends IGraphicsSettings.

ILineSettings is extended by ITickSettings.

Properties

#points

Type Array

Points the line goes through, in pixels from the line's position.

#segments

Type ArraySince 5.1.4

Separate pieces of the line, used when points is not set. Each piece is a list of point arrays drawn as one continuous stroke.

105 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 });
