Properties

34 inherited items
adapter

Type Adapter <this, IDataItemAdapters>Inherited from DataItem

Holds Adapter.

animations

Type Array <Animation>Inherited from DataItem

A list of Animations objects currently mutating Data Item's values.

bullets

Type Dictionary <string, Sprite>Inherited from SeriesDataItem

A dictionary of data items bullets, where key is uid of a bullet template.

categories

Type objectInherited from DataItem

An object containing categories.

category

Type stringInherited from PercentSeriesDataItem

Category.

clonedFrom

Type $type.Optional <this>Inherited from BaseObject

Reference to the original object this object was cloned from. We need to keep this so we can disassociate it from source object when this object is disposed.

config

Type objectInherited from BaseObject

Use this property to set JSON-based config. When set, triggers processing routine, which will go through all properties, and try to apply values, create instances, etc.

Use this with caution, as it is a time-consuming process. It's used for initialchart setup only, not routine operations.

dataContext

Type ObjectInherited from DataItem

Sets to a reference to an original object from Component's data.

A reference to an original object in Component's data, that this Data Item is derived from.

dates

Type objectInherited from DataItem

An object containing dates.

depth

Type numberInherited from DataItem

Depth of the Data Item.

In nested data structures, like TreeMap, this indicates the level this data point is at, in relation to the parent Data Item.

events

Type EventDispatcher <AMEvent <this, IBaseObjectEvents>>Inherited from BaseObjectEvents

An EventDispatcher instance

hasProperties

Type booleanDefault falseInherited from DataItem

Indicates whether Data Item has any properties set.

If it does not have any, the code can use this property to check whether they need to apply costly operation of re-applying properties, whenever Data Item-related element is redrawn, e.g. series.

hidden

Type booleanInherited from DataItem

Sets hidden flag for data item. Mostly used to initially hide data item.

Returns true if this Data Item is currently hidden.

hiddenInLegend

Type booleanInherited from PercentSeriesDataItem

Should dataItem (slice) be hidden in legend?

id

Type $type.Optional <string>Inherited from BaseObject

Sets the user-defined id of the element.

ignoreMinMax

Type booleanInherited from DataItem

Sets whether this data point should not be included in the scale and minimum/maximum calculations.

Exclude from min/max calculations?

E.g. some we may want to exclude a particular data point from influencing ValueAxis scale.

index

Type numberInherited from DataItem

Data Item's position index in Component's data.

isHiding

Type booleanDefault falseInherited from DataItem

Indicates whether Data Item is currently animiting from visible to hidden state.

isTemplate

Type booleanDefault falseInherited from DataItem

Identifies if this object is a "template" and should not be treated as real object that is drawn or actually used in the chart.

label

Type this["_label"]Inherited from PercentSeriesDataItem

A Label element, related to this data item. (slice)

legendDataItem

Type LegendDataItemInherited from PercentSeriesDataItem

A legend's data item, that corresponds to this data item.

locations

Type objectInherited from DataItem

An object containing locations for the Data Item.

A location is a position within date or category, or, in some other cases, where there is no single point but rather some period.

More info: Series: data item locations for info how data item locations work

opacity

Type numberInherited from DataItem

Sets opacity for all Data Item's related elements (Sprites).

parent

Type $type.Optional <this>Inherited from DataItem

When we are using a nested data structure, like for example in a TreeMap, this property points to a parent Data Item of this one.

properties

Type objectInherited from DataItem

An object containing Data Item specific appearance properties in key-value pairs.

Sometimes a single Data Item needs to apply different properties than the rest of the data Series it is part of. E.g. a single column, represented by a Data Item needs to be filled with a different color than the reset of the ColumnSeries it belongs to.

That's where Data Item's properties come into play.

Please note that you should set Data Item-specific properties using setProperty() method, rather than access properties object directly.

slice

Type SpriteInherited from PercentSeriesDataItem

An element, related to this data item. (slice)

Type FunnelSliceInherited from FunnelSeriesDataItem

A FunnelSlice element, related to this data item (FunnelSlice).

sprites

Type Sprite[]Default []Inherited from DataItem

A list of Sprite elements that are associated with this Data Item.

E.g. an Axis Data Item has several separate elements associated with it, like AxisTick, AxisLabel, and Grid.

Data Item keeps track of all of them, so it can toggle all related visual elements when it itself is toggled.

tick

Type this["_tick"]Inherited from PercentSeriesDataItem

A Tick element, related to this data item. (slice)

uid

Type stringInherited from BaseObject

Returns object's internal unique ID.

value

Type numberInherited from SeriesDataItem

data items's numeric value.

values

Type objectInherited from DataItem

An object containing calculated values.

visible

Type booleanInherited from DataItem

Sets visibility of the Data Item.

Returns true if this Data Item is currently visible.

workingLocations

Type objectInherited from DataItem

Current working locations.

Methods

constructor()

Returns PyramidSeriesDataItem

Constructor

23 inherited items
animate(animationOptions: IAnimationOptions[] | IAnimationOptions,
duration: number,
easing?: (value: number) => number)

Returns AnimationInherited from DataItem

Creates and starts an Animation to interpolate (morph) Data Item's properties and/or values.

More info: Animation

clone(cloneId?: string)

Returns thisInherited from BaseObject

Makes a copy of this object and returns the clone. Try to avoid cloning complex objects like chart, create new instances if you need them.

copyFrom(source: this)

Returns voidInherited from DataItem

Copies all properties and related data from different data item.

dispatch(eventType: Key,
data?: any)

Returns voidInherited from BaseObjectEvents

Dispatches an event using own event dispatcher. Will automatically populate event data object with event type and target (this element).

It also checks if there are any handlers registered for this sepecific event.

dispatchImmediately(eventType: Key,
data?: any)

Returns voidInherited from BaseObjectEvents

Works like dispatch, except event is triggered immediately, without waiting for the next frame cycle.

dispose()

Returns voidInherited from SeriesDataItem

Destroys this object and all related data.

getCurrentThemes()

Returns ITheme[]Inherited from BaseObject

Returns a list of themes that should be applied to this element. It could either be a list of themes set explicitly on this element, or system-wide.

getDate(name: string)

Returns DateInherited from DataItem

Returns a Date value of the data field.

getDuration(duration?: number)

Returns $type.Optional <number>Inherited from DataItem

Returns a duration (ms) the Data Item should take to animate from one value to another.

If the duration is not specified via parameter, this method will try to request a default duration from the related Component.

getValue(name: string,
calculated?: CalculatedValue)

Returns $type.Optional <number>Inherited from DataItem

Returns a numeric value for specific data field.

If calculated is not set, it will return a raw value, as it is in source data.

If calculated is set, it will return a pre-calculated specific value.

getWorkingValue(name: string)

Returns $type.Optional <number>Inherited from DataItem

Returns a current working value for a specific data field.

The actual value may differ from the one returned by getValue(). The latter returns static values from the data source.

getWorkingValue() returns current value, which is usually different if Data Item is animating from one state to another.
